Model Context Protocol server for the GBLIN protocol on Base mainnet: an on-chain index of cbBTC, WETH and USDC whose shares are minted at NAV and redeemed pro rata in kind. The server reads live state, verifies governance and risk attestations, and returns unsigned calldata to enter, leave and bid. It never holds keys, signs or broadcasts.
Market risk regime (calm/elevated/crash) and treasury tools for AI agents on Base. Free risk-regime reads, signed EIP-712 risk attestations as portable proof-of-diligence, and JIT swaps to USDC for x402 invoices.
Published on npm as @gblin-protocol/mcp-server.
Documentation and quick start: gblin.digital/agents. Starter examples: examples/.
calm / elevated / crash) read from the vault's on-chain Crash Shield, with a severity score and a risk postureoutputSchema on every tool that returns an object, so a client can validate results and generate typesEvery tool is free. The server never charges: revenue comes from the on-chain protocol fee when an agent actually uses GBLIN. Verifiable pay-per-call lives on the HTTP endpoints listed under x402 endpoints.
Previous deployments (0x36C81d7E1966310F305eA637e761Cf77F90852f0, 0x38DcDB3A381677239BBc652aed9811F2f8496345) are superseded. Nothing is read from them; holders migrate through the web app.
Fees: 0.10% on every mint with ETH or WETH (0.05% stays in the vault and lifts the NAV of every share, 0.05% is minted as shares to the fee recipient); in-kind deposits pay a 0.50% floor plus a deviation tax; a 0.50% yearly management fee accrues as shares; redemption in kind and transfers carry no fee.
A stateless Streamable HTTP server runs at https://mcp.gblin.digital/mcp — no install, no auth, no session, 60 requests per minute per IP. It serves the vault, action and payment tools of this package under two-level names (treasury.*, actions.*, payments.*, governance.state, auction.state, attestation.verify), built from the same source, plus the risk, receipts and coherence tools; the snake_case names below are accepted there as aliases. It also serves search and fetch, the two read-only tools research clients expect (ChatGPT deep research among them): search returns matching documents (the protocol's documentation, one card per tool, the live vault state) and fetch returns one document's full text. Every step returned by the action tools carries both spellings, target/calldata and to/data/chainId, so it maps one to one onto wallet batch APIs such as send_calls. GET-only audit surfaces: /meta, /tools.json, /resources.json, /conformance. Also listed on Smithery. A second surface, https://mcp.gblin.digital/mcp/directory, serves the same tools except payments.relay, the one tool that submits a signed transfer on the caller's behalf; it exists for connector directories that accept software which reads, simulates, verifies and prepares unsigned calldata but not software that executes transfers. /meta reports it under directory_surface.
packages/agent-treasury — npm @gblin-protocol/agent-treasury. Operating cash stays in USDC, the surplus above a
reserve is parked in GBLIN, and USDC is pulled back from GBLIN just in time when an x402 invoice arrives. The x402 client is
Coinbase's reference x402Client with the refill attached to its onBeforePaymentCreation hook, so a 402 for USDC on Base
triggers the refill before the authorization is signed and a price above the cap is refused before anything is signed.
Self-custody, no key leaves the process. Verified end to end on a fork of Base (24 checks: park, refill, cooldown, a
mock invoice with the challenge bytes of gblin.digital and a verified EIP-712 signature, the cap).

Every tool sets MCP tool annotations:
Calldata builders are read-only: they return bytes, they do not send them. prepare_gblin_payment is not idempotent because every call draws a fresh nonce. Sealing appends to a public log and is never destructive. relay_gblin_payment moves the payer's funds on chain, so it is marked destructive and clients should confirm before calling it. Every tool also carries a human-readable title.
Every tool except seal_action_demo declares an outputSchema. A successful result carries the same object as structuredContent and as JSON text. The required list of each schema is the contract: fields a successful call always returns. Other fields are described but optional, and the schemas accept additional fields, so adding one is not a breaking change. Errors carry isError: true and no structured content.

Pay-per-call data lives on HTTP, settled in USDC on Base through the Coinbase CDP facilitator with gasless EIP-3009 transferWithAuthorization. Clients such as @x402/fetch handle the 402 challenge, the signature and the retry.
Machine-readable manifest: https://gblin.digital/.well-known/x402. Payment recipient: 0x0ebA5d314F4f5Dcb7A094953Fa9311a45172dd1B.
GET https://gblin.digital/api/x402/attestation returns a ten-minute, verifiable snapshot of the BTC/ETH risk regime, signed under the EIP-712 domain GBLIN Risk Attestation, version 2, chain 8453, verifying contract = the vault in service. The response embeds its domain, types and message under eip712; a verifier recovers the signer and checks it against the published attestor address, which it should pin. verify_risk_attestation does this offline and also accepts attestations issued under domain version 1.
A public, append-only RFC 6962 transparency log for AI actions. Input and output go in as hashes only; the short action, agent_id, tool and meta strings are published in clear, so put identifiers there, never secrets. Each seal returns a portable receipt:
receipt = canonical payload
+ Ed25519 signature (key: gblin.digital/receipts-log)
+ RFC 6962 inclusion proof (leaf → Merkle root)
+ C2SP signed checkpoint (origin, tree size, root)
Canonicalization is frozen as gblin-canonical-json/1: object keys sorted by UTF-16 code unit, no whitespace, JSON.stringify semantics for primitives, recursion for objects and arrays. Test vector: payload {"b":1,"a":null} → canonical {"a":null,"b":1} → leaf = SHA256(0x00 || canonical_bytes). The receipt signature is Ed25519 over "gblin-receipt/v1\n" + canonical.

GBLIN pre-registers hash-pinned promises and runs an automaton that probes them every ten minutes and seals each closed day as an EAS attestation on Base. Free report: /coherence. Live promises: uptime of the paid attestation endpoint, and honesty of the public agent-economy counters, with the protocol's own wallets disclosed. GBLIN is a registered ERC-8004 agent (#59286).
get_auction_state exposes it.analyze_treasury_health.transferWithAuthorization, receiveWithAuthorization, cancelAuthorization), so an agent can settle in GBLIN the way it settles in USDC.
