0xinsider Agent Plugin

skills.sh

The official Agent Plugin for 0xinsider - Polymarket analytics for sports and esports in real-time.

It bundles the 0xinsider MCP server with five skills that teach an agent how to read large trades, wallet grades, sharp-money flow, and published research without misreporting them.

Install

npx skills add 0xinsider/agent-plugin

Refresh the changed instructions in an existing installation with:

npx skills@latest update 0xinsider-api-access polymarket-sharp-money

Or install one skill without adding the whole plugin:

npx skills use 0xinsider/agent-plugin@0xinsider-api-access

Contents

SkillCovers
0xinsider-api-accessCredentials, sandbox vs live hosts, MCP transports, rate limits, typed errors
polymarket-whale-tradesLarge-trade feed, history replay, counterparties, significance score
polymarket-wallet-gradesTrader grades, settled P&L and its trust metadata, leaderboards, position timelines
polymarket-sharp-moneyDirectional flow, market intel, Max-only Edge Hunter board/full signals/cohort observations, Insider Radar flags
polymarket-market-researchMarket search and explore, published research, report snapshots

Plugin 1.2.0 documents configurable selections across every Edge Hunter view: sports/esports, canonical sports, exact leagues, market types, markets, events and series. Board defaults remain compatible; rows add frozen market_context for authoritative selector discovery, and selected responses echo normalized selection. Advanced records retain pagination, evidence and conditional reads. The coordinated TypeScript SDK is 0.22.0 and CLI/MCP runtime is 3.2.0. The four legacy URLs/tools remain retired.

AGENTS.md holds the rules for AI coding agents writing integration code against the API. .cursorrules mirrors it.

MCP server

mcp.json points at the remote Streamable HTTP endpoint:

{
  "mcpServers": {
    "0xinsider": {
      "type": "http",
      "url": "https://0xinsider.com/mcp",
      "headers": { "Authorization": "Bearer ${OXINSIDER_API_KEY}" }
    }
  }
}

The server exposes tools across traders, markets, large trades, positions, flow, research, reports, and webhooks. Its card is at /.well-known/mcp.

A local stdio path ships in the CLI:

npx -y @0xinsider/[email protected] init

Try it with no account

Every documented operation answers from the sandbox with no credential:

curl -s https://0xinsider.com/sandbox/api/v1/leaderboard

One POST returns a sandbox key and the steps to live access:

curl -s -X POST https://api.0xinsider.com/api/v1/agents/register \
  -H 'Content-Type: application/json' -d '{"name":"my-agent"}'
