Polyester MCP is a hosted Model Context Protocol server. It lets AI assistants (Cursor, Claude Desktop, and other HTTP MCP clients) query Polyester documentation and read live platform configuration — no local setup required.
Connect with a URL only. You do not need to clone a repository or configure environment variables on your machine. The snippet uses the Polyester network this docs site is on.
Connect in Cursor
Add to Cursor Settings → MCP or your workspace .cursor/mcp.json:
{ "mcpServers": { "polyester": { "url": "https://polyester-mcp-testnet.fabriclabs.workers.dev/mcp" } }}Reload MCP in Cursor after saving.
Other clients
Claude Desktop and other clients that support remote MCP over HTTP (Streamable HTTP) can use the same URL. Check your client’s documentation for how to add a remote MCP server URL.
