0xinsider 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.

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 33 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 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"}'
