BlockRun MCP is an open-source Model Context Protocol server that gives Claude — and any MCP-compatible agent — 19 tools for real-time data and real actions: 88 LLMs, image & video generation, prediction-market data, live web/X search, on-chain queries across 40 chains, and the ability to place real, USDC-settled bets on Polymarket.
You pay per call, and you choose how. Wallet mode authenticates with a signature and settles each call in USDC via the x402 protocol — no account, no credit card, no subscription, on Solana or Base. Account mode authenticates with a BlockRun API key (brk_live_…) from user.blockrun.ai, routes service calls through api.blockrun.ai, and draws down card- or wire-funded account credit at exact usage. Same 19 tools either way. MIT licensed.
Read live Polymarket odds and place the bet, from one self-custody wallet, pay-per-call. Jump to Polymarket trading →
Every other data integration was built for human developers — create an account, copy an API key into .env, add a credit card, repeat for every vendor.
BlockRun gives you both payment rails without rebuilding the integration. Use a wallet when the agent should self-custody funds, or use an account key when a team wants card-funded credits and a dashboard.

Before BlockRun, Claude can't answer:
After BlockRun, it can. Each query costs fractions of a cent — billed from a local USDC wallet, or from card-funded credit on a BlockRun account through api.blockrun.ai. No subscriptions, no per-vendor signups.
Both modes reach the same 19 tools. Account mode sends service calls to https://api.blockrun.ai by default. You can switch at any time; setting BLOCKRUN_API_KEY takes priority over a wallet, and unsetting it hands the wallet back.
Claude Code (recommended)
claude mcp add blockrun -s user -- npx -y @blockrun/mcp@latest
-s user installs globally (available in every project). The -- separator ensures -y is passed to npx, not parsed by claude mcp add.
💡 Homebrew / nvm users: if the server doesn't connect, Claude Code likely can't find
node/npxon its launcher PATH. Pass your shell PATH through — works on CLI and desktop:claude mcp add blockrun -s user -e PATH="$PATH" -- npx -y @blockrun/mcp@latestSee Troubleshooting if it persists.
Every MCP client — one command or one JSON block. Verified = we ran the published package on that client and saw the tools listed (client version · date). Documented = install path from the client's own docs; not run by us yet — tell us if it works. The Spend dialog column is whether the client renders the human-in-the-loop payment prompt; on ❌ clients paid calls proceed without asking and BLOCKRUN_BUDGET_LIMIT is the guard.
Any other MCP client that can spawn a stdio server works the same way: command: npx, args: ["-y", "@blockrun/mcp@latest"]. With nvm/Homebrew Node on a JSON-configured client, put the absolute path from which npx in command. Spend-dialog sources and what "proceeds without asking" means: docs/spend-confirmation.md.
Grok — raise the startup timeout before you install, or the first run looks broken.
Grok waits startup_timeout_sec for an MCP server to answer, and it defaults to 30
(xAI's MCP docs). A first npx -y run has
to download this package and its dependency tree before the server can say anything, and
that is a race: measured cold, with an empty npm cache, it took 17s on a fast connection
and 42-46s on a slower shared box. Lose the race and grok mcp doctor blockrun says
server timed out (no response within 30s) and the UI shows blockrun [unavailable] — an
install that is working, timing out, and indistinguishable from broken.
Give it room in ~/.grok/config.toml (or .grok/config.toml for one project):
[mcp_servers.blockrun]
command = "npx"
args = ["-y", "@blockrun/mcp@latest"]
enabled = true
startup_timeout_sec = 120
Or skip the cold download entirely, which is faster every run after the first:
npm install -g @blockrun/mcp@latest
grok mcp add blockrun -- blockrun-mcp
Only the FIRST run pays this: npx caches by exact spec, so the next start is warm (~9s
here). The same trap exists on any client with a startup timeout — if a fresh install
shows as unavailable and npx -y @blockrun/mcp@latest runs fine in a terminal, raise the
client's timeout or install globally before looking for anything else. Thanks to
@0xCheetah1 for the report.
OpenClaw: the published npx package was verified end-to-end on 2026.8.2: all 20 tools were projected (19 since the Surf delisting), free calls worked, and paid x402 calls settled. Add a hard session cap while installing:
openclaw mcp set blockrun '{"command":"npx","args":["-y","@blockrun/mcp@latest"],"env":{"BLOCKRUN_BUDGET_LIMIT":"2"}}'
openclaw mcp doctor blockrun --probe
Spend confirmation depends on the OpenClaw runtime and chat surface. Its Codex harness supports MCP form elicitation, but an unmappable prompt is returned as an explicit decline; in the WebChat → Codex route tested here, BLOCKRUN_CONFIRM_SPEND=on declined paid calls without presenting an actionable dialog. Keep confirmation off on that route and rely on BLOCKRUN_BUDGET_LIMIT plus OpenClaw's own tool-approval mode.
{
"mcpServers": {
"blockrun": { "command": "npx", "args": ["-y", "@blockrun/mcp@latest"] }
}
}
Add "env": { "BLOCKRUN_CONFIRM_SPEND": "on" } inside the server object to turn on the spend dialog where the client supports it.
Expose a trimmed tool set so the client loads fewer schemas into context. Pass --profile <name> (or set BLOCKRUN_MCP_PROFILE); omit for the full set.
blockrun_surf was removed in 0.49.0: the gateway has answered every Surf (asksurf.ai) path with 410 since 2026-09-06, so the tool could only ever return an error, and its schema cost every agent context on every turn. Those questions go to blockrun_price, blockrun_defi, blockrun_markets and blockrun_dex; the surf skill maps each former endpoint to its replacement.
claude mcp add blockrun-trading -s user -- npx -y @blockrun/mcp@latest --profile trading
# Codex CLI
codex mcp add blockrun-trading -- npx -y @blockrun/mcp@latest --profile trading
An unknown profile name falls back to full. modal and phone are full-profile only.
Installing an MCP server spends context on every turn, whether or not you call the tools — the client loads each tool's schema into the model's prompt and re-sends it for the whole session. Package managers have shown install size for decades. Almost no MCP server shows this. Ours:
Running --profile trading instead of the default costs 61% less context for the same trading
workflow. If you only ever ask about markets, that is the single cheapest change you can make.
Measure it yourself — against us, or against any other stdio MCP server:
npm i gpt-tokenizer
node scripts/measure-tool-schema.mjs # this server, every profile
node scripts/measure-tool-schema.mjs -- npx -y @some/other-mcp-server
It counts the model-visible projection — {name, description, input_schema} per tool, with the
mcp__blockrun__ prefix the host prepends — because that is what lands in the API tools array.
It excludes annotations, _meta and outputSchema, which the host consumes and never forwards
to the model (a further ~3.7% on the wire).
The tokenizer is o200k_base. Claude's tokenizer is not public and runs a few percent higher on
JSON, so every figure here is a slight under-count, never an over-count.
Two caveats worth stating plainly. Tool schemas sit at the front of the prompt and are covered by prompt caching, so after the first turn they re-send at cache-read rates — the context-window cost is 100% every turn, the dollar cost is roughly a tenth of that. And 54% of our own cost is tool descriptions, not schemas, which is where the remaining work is.
Option A — API key + account credit (no wallet). Sign in at user.blockrun.ai with Google. This is the dashboard for keys, credits, and activity; the MCP uses the key to call api.blockrun.ai for the actual services.
brk_live_… and is shown once.https://api.blockrun.ai:claude mcp add blockrun -s user -e BLOCKRUN_API_KEY=brk_live_… -- npx -y @blockrun/mcp@latest
Or export BLOCKRUN_API_KEY=brk_live_… in the environment the client launches from.
If your client makes environment variables awkward, write the key to
~/.blockrun/.api-key instead (chmod 600) — same file directory the
wallet uses. The environment variable wins when both are present.
4. Dashboard → Activity — every call, priced at exact usage.
Verify with blockrun_wallet action:"status" — it reports the account, its real
balance, and what this session has spent:
Paying with: BlockRun account API key (no wallet, no chain)
Account: acme (gated)
Credit remaining: $12.5000 of $50.00 granted
Top up: https://user.blockrun.ai/dashboard/credits
Invoiced accounts show Spent to date: $4.5239 (invoiced account — no prepaid ceiling) instead. If the account is blocked, status says so and why before you spend a call finding out.
Option B — wallet (no account). Run blockrun_wallet to see your addresses. New installs default to Solana; send USDC (SPL) on Solana from Coinbase (pick "Solana"), Phantom, Solflare, or Backpack. To pay on Base instead: blockrun_wallet action:"chain" chain:"base", then send USDC on Base. Full instructions: Fund your wallet.
$5 covers ~525 market queries · ~500 Exa searches · ~250 image generations · ~14 Seedance 1.5-pro clips.
"What's Polymarket saying about the next Fed decision? If 'hold' is above 70%, put $2 on it."
Claude reads the odds with blockrun_markets. In wallet mode, and only after your confirmation, it can also place the trade with blockrun_polymarket. In API-key mode, the data/media/research calls run through api.blockrun.ai; Polymarket trading still requires a local keypair to sign.
The package ships 17 skills — which tool answers what, worked examples, and a setup / debug / upgrade trio so the agent can install, troubleshoot and update the server on its own.

User: What's Polymarket saying about the Fed rate decision next month?
Claude: According to Polymarket, the market puts a 73% probability on the Fed holding rates steady, 24% on a 25bp cut, 3% on a hike. 24h volume: $2.1M. The "Hold" contract last traded at $0.73.
(via
blockrun_markets· cost: $0.0085 on Base — $0.0075 + the $0.001 network fee)
User: Polymarket has Hawley at ~13% to announce a 2026 presidential run — put $1 on Yes.
Claude: Done — bought 7.63 shares of Yes at $0.131 ($1.00, market FOK). Real on-chain order, settled in pUSD from your gasless Polymarket deposit wallet; I'm tracking the position now.

Flat data prices are the base. In wallet mode the gateway adds its flat network fee on top — $0.001 per call on Base today, and the Solana gateway quotes the base alone; the account rail charges no fee. The exact figure is in the payment-required header of any unpaid request, which is free to ask for. The server reserves $0.002 for the fee against the budget cap, so blockrun_wallet action:"report" and the spend-confirmation dialog run $0.001 high per call by design.
blockrun_marketsblockrun_markets reads, blockrun_polymarket action:"buy" places. Gasless, confirm-gated.blockrun_markets polymarket/wallet/identity/:wallet + .../clusterblockrun_exablockrun_imageblockrun_speechblockrun_phoneblockrun_wallet delegate × 3blockrun_rpcblockrun_polymarket lets an agent place real bets on Polymarket (CLOB V2, Polygon). It is non-custodial: every order and approval is EIP-712-signed locally by your BlockRun wallet key — the same self-custody key that pays x402 API fees on Base also authorizes bets on Polygon. Neither BlockRun nor Polymarket's relayer can move funds; they only forward payloads you signed.
Architecture — the official "deposit wallet" path (signature type POLY_1271): a smart-contract vault on Polygon, CREATE2-derived from your key (only your key can authorize it), holds betting funds in pUSD (Polymarket's 1:1 collateral wrapper). Deployment, approvals, and redemptions all run gasless through Polymarket's relayer — you never need POL.
📖 Full step-by-step guide: docs/polymarket-trading-setup.md
# 1. Provision your deposit wallet (idempotent, gasless)
blockrun_polymarket action:"setup"
# 2. Fund it from your Base USDC in one call (gasless; $0.01 fee, non-custodial)
blockrun_polymarket action:"fund" amount_usd:5 confirm:true
# 3. Sign the one-time gasless approval batch
blockrun_polymarket action:"setup" confirm:true
# 4. Find a market, preview safely, then place only after exact user approval
blockrun_polymarket_read action:"preview" side:"buy" token_id:"<id>" amount_usd:5 order_type:"FOK"
blockrun_polymarket action:"buy" token_id:"<id>" amount_usd:5 order_type:"FOK" confirm:true
# 5. Manage → positions · orders · cancel · sell · redeem · withdraw
Safety rails (server-side; an agent cannot bypass them): confirm:true required for every order/approval/redeem, POLYMARKET_MAX_BET_USD per-order cap (default $25), optional POLYMARKET_MAX_SESSION_USD session cap, and bets never draw from the x402 API budget.
Regions: Polymarket geoblocks order placement by IP (US/UK + many regions). Handled by default — the MCP routes CLOB traffic through BlockRun's hosted Finland egress (a fully unrestricted region under Polymarket's policy), so trading works out of the box; setup reports your status. Override POLYMARKET_CLOB_HOST to go direct or run your own egress, optionally reached via HTTPS_PROXY / POLYMARKET_CLOB_PROXY (a proxy alone doesn't change the Polymarket-facing egress). Complying with Polymarket's terms for your jurisdiction is your responsibility.
⚠️ Back up your signer key (
~/.blockrun/.sessionby default; aBLOCKRUN_WALLET_KEYenv var or an existing agentwallet.jsontakes precedence —setupprints the actual signer address). It is the only key to both the payment wallet and the Polymarket deposit wallet.
Turn on BLOCKRUN_CONFIRM_SPEND=on and every paid tool pauses before it signs. The server sends an MCP elicitation; your client renders it as a dialog with the estimated charge:
💸 BlockRun charge — video · bytedance/seedance-2.5 · 10s
Estimated: $2.6500
Approve this spend? (USDC is debited per call.)
To stop the charge, choose Decline — Cancel/ESC lets it proceed.
[ ] Approve all BlockRun charges for the rest of this session (don't ask again)
[ Decline ] [ Approve ]
Decline → nothing is sent, nothing is charged, the tool reports "Charge declined". Approve → the call proceeds. Tick the box and you're not asked again for the session. Free calls never prompt. Set BLOCKRUN_CONFIRM_THRESHOLD=0.05 to only be asked above $0.05.
claude mcp add blockrun -s user -e BLOCKRUN_CONFIRM_SPEND=on -e BLOCKRUN_CONFIRM_THRESHOLD=0.05 -- npx -y @blockrun/mcp@latest
On a client that can't ask, the gate fails open — the call proceeds and the cost footer reports the charge. The hard stop on every client is the budget: BLOCKRUN_BUDGET_LIMIT for the process, blockrun_wallet action:"delegate" per sub-agent. blockrun_polymarket keeps its own, stronger per-order confirm:true.
📖 When to use it, sources for the matrix, limitations: docs/spend-confirmation.md
On hosts that support the MCP Apps extension — Claude Desktop, claude.ai, VS Code, Cursor, ChatGPT — two tools render as interactive cards instead of text. Everywhere else (Claude Code, Codex, terminals) nothing changes.
blockrun_polymarket_read action:"preview" — question, outcome, side, best quote, est. shares, notional, cap meter, session ledger. Edit the amount → Re-quote. Place order is arm-then-confirm and asks the host to call blockrun_polymarket … confirm:true, so the host's consent prompt and every server cap (POLYMARKET_MAX_BET_USD, session cap) still apply.blockrun_wallet — both chains' balances, switch chain, copy address, EIP-681 / Solana Pay QR, explorer, Buy USDC with card.📖 Hosts, money path, local testing: docs/mcp-apps.md
Paying with an API key instead? There is no wallet to fund — top up credit by card or wire at user.blockrun.ai/dashboard/credits. The MCP will use that key against api.blockrun.ai and skip the wallet rail entirely.
The server keeps two wallets — one on Solana, one on Base — and pays from one at a time. Run blockrun_wallet to see both addresses, balances, and which is active.
$5 covers ~525 market queries, ~500 Exa searches, ~250 image generations, or ~14 Seedance 1.5-pro clips (5s @ 720p+audio, ~$0.35 each).
blockrun_wallet action:"setup" # shows the Solana address + funding QR
Send USDC (SPL) on the Solana network — from Coinbase (pick "Solana"), Phantom, Solflare, or Backpack.
One tool call — no env vars, no file editing, no restart:
blockrun_wallet action:"chain" chain:"base" # provisions + activates the Base wallet
blockrun_wallet action:"setup" # shows the Base address + funding QR
Switch back with blockrun_wallet action:"chain" chain:"solana". Switching only changes which wallet pays; both keep their balances.
Upgrading from an older version? Nothing moves. The Solana-first default applies only to installs with no wallet and no saved chain preference — if you already have a Base wallet, you stay on Base until you switch.
Almost everything now settles on either chain. The exceptions:
A blocked capability returns a message naming the fix, not a raw error.
Anything estimated is printed with a ~ and says so. Estimates run high on
the account rail — they add a transaction fee it does not charge — so a budget
cap trips early rather than late. The source of truth is always
Dashboard → Activity.
If you are an LLM invoking BlockRun MCP tools, read these first:
blockrun_wallet first to check status, then action:"setup" for funding. Don't retry the failing tool blindly — the wallet is empty.blockrun_polymarket moves REAL user funds (pUSD on Polygon), separate from the x402 API budget. Never buy/sell/redeem with confirm:true unless the user explicitly approved that exact trade; without confirm you get a safe dry-run. Discover markets/token IDs with blockrun_markets first.blockrun_music and blockrun_video are payment-on-completion async. Failures / client timeouts do NOT charge. Don't retry-loop — they may take 60–180s.blockrun_wallet action:"delegate" agent_id:"X" agent_limit:1.00, then pass agent_id:"X" to every downstream call. The child is auto-blocked at zero.blockrun_chat mode:"free" (NVIDIA), blockrun_dex, blockrun_price (crypto/FX/commodity), and blockrun_models are $0.Posters generated through blockrun_image with openai/gpt-image-2 — each a single API call routed through BlockRun, paid from either account credit or a USDC wallet.
Prompts and a worked example are in skills/image-prompting/SKILL.md.
One wallet, or one dashboard-backed API key. All sources.
Chain selection priority (src/utils/wallet.ts), highest first: .chain preference → SOLANA_WALLET_KEY → .chain-auto pin → non-empty .solana-session → Solana key in the OS keychain → an existing Base wallet keeps Base → otherwise Solana (a fresh install with no wallet at all).
That second-to-last step is the upgrade guard: without it, flipping the default to Solana would move every existing Base-only user onto an empty wallet, and their next paid call would fail on a zero balance with nothing on screen explaining why. None of this applies in account mode — BLOCKRUN_API_KEY has no chain.
The server runs a non-blocking npm registry check at startup and prints an Update available notice to stderr when a newer @blockrun/mcp exists — re-run the install command to upgrade.

Re-run the install.fetch failed / balance-check timeout → Base RPC transient outage. The tool falls through 3 public RPCs; retry after 30s. Persistent = local proxy / firewall blocking outbound RPC.Video/Music generation timed out → Upstream queue congestion. Whether it cost anything depends on the rail, and the error says which: on the Base wallet payment settles on completion, so it is not charged and a retry is safe; on Solana music and every account-rail media job the gateway bills at submit, so the job is charged, the error names it, and re-running bills a second one — check blockrun_wallet action:"report" instead.blockrun_price says Equity quotes are not served (gateway 501 …) → Equity price/history were withdrawn on 2026-09-05; not an outage, and nothing was charged (the wallet is never asked to sign). The ticker catalog (action:"list" category:"stocks") is still free. Equity coverage: [email protected].blockrun_markets on sports/* fails — before 0.49.0 as API error after payment: 502 with no balance change → Predexon's sports/* routes have been down upstream since 2026-08-04; the gateway releases the payment on that upstream 500, so the call is not charged (the error says so when the gateway's "payment NOT charged" confirmation is in the response; otherwise it tells you to check blockrun_wallet action:"report"). For sports odds use path:"markets/search" with params:{ q: "NBA" }, or polymarket/events with params:{ search: "NBA" } — the bare markets route and its league filter were removed upstream on 2026-08-04 and 404 before payment. Upgrade to ≥ 0.49.0 so the error says all of this itself.BLOCKRUN_CONFIRM_SPEND=on → Your client doesn't support MCP elicitation (Windsurf, Codex, Gemini CLI); the server proceeds without asking by design.

See the setup guide.What is BlockRun MCP? An open-source MCP server that gives Claude and other agents 19 tools for real-time data and real actions (trading, media, on-chain), paid per call — from a self-custody wallet or a BlockRun account key.
Do I need an API key or an account? No. A wallet is auto-created locally on first run; you fund it with USDC and there are no signups, dashboards or keys to rotate.
But you can have one. If your team can't hand a wallet to an agent, sign in at user.blockrun.ai, mint a key at Dashboard → Keys, top up account credit by card or wire at Dashboard → Credits, and set BLOCKRUN_API_KEY. The MCP then sends paid service calls to api.blockrun.ai and bills exact usage against that account credit — no $0.001 per-call network fee, no per-call minimum — with a ledger at Dashboard → Activity. Everything works except the parts that genuinely need a keypair: Polymarket trading, wallet balances/top-ups, and the wallet-indexed blockrun_realface action:"list".
Which is cheaper? Account billing, slightly — it charges exact metered usage with no per-call minimum and no $0.001 transaction fee. Wallet mode buys you self-custody and Polymarket trading instead.
How much does it cost?
Pay-per-call — fractions of a cent to a few cents. The free tier (blockrun_chat mode:"free", blockrun_dex, crypto blockrun_price, blockrun_models) is $0. $5 of USDC or account credit covers thousands of queries.
Is it safe / non-custodial?
Yes. Your private key never leaves your machine (~/.blockrun/.session by default, 0600). x402 payments and Polymarket orders are signed locally — BlockRun forwards signed payloads and cannot move your funds.
Which clients work? Any MCP client that can spawn a stdio server. Verified on Claude Code and Codex CLI, in daily use on OpenClaw; install paths documented for Claude Desktop, Cursor, VS Code, Gemini CLI and Windsurf — see the client table. The spend-confirmation dialog additionally needs MCP elicitation (Claude Code, Cursor, VS Code).
Does it have a UI? On MCP-Apps hosts (Claude Desktop, claude.ai, VS Code, Cursor) the Polymarket preview is a live order card and the wallet is a panel — see MCP Apps ↑. Terminal clients get the same information as text.
Can I make the agent ask before it spends?
Yes — BLOCKRUN_CONFIRM_SPEND=on. Every paid tool pauses with the estimated charge and nothing is signed until you approve. Human-in-the-loop payments ↑
Can it really place real bets?
Yes. blockrun_polymarket places real, USDC-settled orders on Polymarket's CLOB — confirm-gated and capped. Read the odds with blockrun_markets, place with blockrun_polymarket.
Base or Solana?
Both. Switch instantly with blockrun_wallet action:"chain". Three things are Base-only, and each says so when you call them on Solana: blockrun_defi (DefiLlama) and blockrun_modal, which the Solana gateway does not serve, and claude-* chat with thinking (the native /v1/messages path pays on Base; a plain claude-* call takes the compat path on Solana). Media generation, markets, search and Polymarket all settle on either chain.
