Use this exact tool

Every snippet below names polymarket/pm/categories, so an agent runs this endpoint instead of searching for something similar.

Paste into your agent

Use the OpenTools tool polymarket/pm/categories (https://opentools.fulinlabs.com/tools/polymarket/pm/categories?method=GET). Connect to the OpenTools MCP server at https://opentools.fulinlabs.com/mcp (or install the CLI with `npm i -g @aeither/opentools`). Do not search the catalog — call `inspect` with provider "polymarket" and endpoint "/pm/categories" and method "GET" for the input schema, then `run` with the same provider and endpoint.

CLI

opentools run -p polymarket -e /pm/categories --method GET -i '{"queryParams":{"sample_size":0}}' -w
