# 0xinsider MCP server

0xinsider builds Polymarket analytics & infrastructure for sports and esports markets. Its remote MCP server is a read-only Streamable HTTP endpoint at https://api.0xinsider.com/api/v1/mcp. initialize, ping, and tools/list need no credential. tools/call takes Authorization: Bearer with an OAuth 2.1 access token (an MCP client that supports the MCP authorization spec signs you in and asks you to approve it) or an API key. The server exposes typed tools for traders, markets, large trades, positions, reports, and search. GET https://0xinsider.com/.well-known/mcp returns the public server card. POST to that alias or to the API endpoint for the authenticated transport. A second, documentation MCP server at https://docs.0xinsider.com/mcp needs no credential and answers questions from the developer docs (search, read a page); use it to learn the API, and the product server to act on data.
