Details
From the project README0xinsider Agent Plugin
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
| Skill | Covers |
|---|---|
0xinsider-api-access | Credentials, sandbox vs live hosts, MCP transports, rate limits, typed errors |
polymarket-whale-trades | Large-trade feed, history replay, counterparties, significance score |
polymarket-wallet-grades | Trader grades, settled P&L and its trust metadata, leaderboards, position timelines |
polymarket-sharp-money | Directional flow, market intel, Max-only Edge Hunter board/full signals/cohort observations, Insider Radar flags |
polymarket-market-research | Market 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"}'

New to MCP?
From what the protocol is to installing your first server, these answers cover most first questions.
An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
