What the code does

Evidence

Things with no honest explanation: a promise that contradicts the code, code that runs at install time while hiding what it does, data leaving the machine.

Claims read-only, but the code runs commands mcp/src/runner.ts:32
    const child = spawn(process.execPath, [...NODE_ARGS, ...argv], {
Capabilities

What this server is able to do. For an MCP server this is often the job itself — a terminal server runs commands because that is what it is for. Listed so you know what you are plugging in, not as an accusation.

Runs an external command mcp/src/runner.ts:32
    const child = spawn(process.execPath, [...NODE_ARGS, ...argv], {

Is this your server and something here is wrong? Tell us — corrections are free and do not require a plan.

We found things in this code

Code changes quietly between releases, and nobody reads the diff of a dependency. We do, on every release — watch Polymarket Toolkit and you get told the day something new turns up.

Polymarket Toolkit — questions

Answers built from our own checks of this server.

Why is there no uptime for Polymarket Toolkit?
Polymarket Toolkit runs on your own machine over stdio — there is no network address to reach, so uptime cannot be measured for it by anyone. What can be measured is adoption: the npm package polymarket-toolkit-mcp was installed 96 times last week.
How do I connect Polymarket Toolkit?
Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It runs locally, so the command pulls polymarket-toolkit-mcp straight from npm; nothing to host, nothing to sign up for.
How many people use Polymarket Toolkit?
The npm package polymarket-toolkit-mcp was installed 96 times in the last week. Week over week that is +14%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.
Is Polymarket Toolkit open source?
Yes — it is published under the MIT licence, written in TypeScript, 201 stars on GitHub and 1 open issue. The source link is on this page, so you can read exactly what it does with your data before you connect it.
