Frequently asked questions

1

What API does Polymarket MCP Server use?

It uses Polymarket's Gamma Markets API, with the environment variable `GAMMA_API_URL` defaulting to `https://gamma-api.polymarket.com`.

2

How do I configure authentication?

Set `GAMMA_REQUIRES_AUTH` to `false` (default) for read-only access, or to `true` if you need authenticated access. The server supports environment variables via a `.env` file.

3

Can I choose which tools are available to the MCP client?

Yes, the list of tools is configurable, so you can select only the tools you need to avoid taking up too much of the context window.

The server is written in Python and uses `uv` for dependency management. It can be run directly with `uv` or via Docker. For Docker, you must build the image first with `docker build -t polymarket-mcp-server .`.

5

What should I do if I see "Error: spawn uv ENOENT" in Claude Desktop?

Specify the full path to `uv` in the `command` field of the server configuration, or set the environment variable `NO_UV=1` in the configuration.
