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.

Builds a file path from a variable leaderboard-server/server/jobs/backup.py:19

    dest = os.path.join(backup_dir, f"leaderboard-{ts}.db")

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

This code can reach further than it looks

We found places where it runs commands, builds paths or queries from values it is given. None of that is a flaw by itself — it becomes one when the code changes, and code changes quietly between releases. We re-read it on every one.

Connect this server

This server runs on your own machine — install it with the package manager and the client starts it for you. Package name taken from the official registry entry.

Polymarket Paper Trader — questions

Answers built from our own checks of this server.

Why is there no uptime for Polymarket Paper Trader?

Polymarket Paper Trader 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 pypi package polymarket-paper-trader was installed 787 times last week.

How do I connect Polymarket Paper Trader?

Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It runs locally, so the command pulls polymarket-paper-trader straight from pypi; nothing to host, nothing to sign up for.

How many people use Polymarket Paper Trader?

The pypi package polymarket-paper-trader was installed 787 times in the last week. Week over week that is -61%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.

Is Polymarket Paper Trader open source?

Yes — it is published under the MIT licence, written in Python, 492 stars on GitHub and 2 open issues. The source link is on this page, so you can read exactly what it does with your data before you connect it.
