Overview

AI-generated overview

A local MCP server that scans installed MCP servers, or a GitHub, GitLab, npm or PyPI URL, for security issues and returns trust scores.

What you can do
Discover MCP servers configured in Claude Code, Cursor, Windsurf or Gemini CLI and scan them with 16 engines, returning a summary table of trust scores and findings. Scan a single GitHub, GitLab, npm or PyPI URL and get a trust score, engine breakdown and findings. Retrieve detailed results for a specific scan by its ID. Check daily quota usage and remaining scans.
When to use it
Useful when you want a quick security check of the MCP servers already configured in your editor, or of a third-party MCP package or repository before installing it.
Requirements
Runs locally as a Python package via uvx. Requires an MCPAMPEL_API_KEY environment variable, obtained by registering for a free account; an optional MCPAMPEL_BASE_URL overrides the API endpoint. Network access to the scanning service is needed.
Before you install
The API key is a secret passed in the environment. Scanning sends your editor's MCP server configuration and the URLs you submit to a third-party service. The free tier is limited to 50 API calls per day.

Installation

In SourceWeft

  1. Open MCPAmpel - MCP Security Scanner in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Desktop only via STDIO. STDIO servers start a local process, so they need the SourceWeft desktop host.

Other MCP clients

Follow the launch instructions in the repository.

Score

50% of the applicable checks met

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.

  • Reached in the last 30 days25 pts

    Keep the endpoint answering the MCP handshake; SourceWeft probes it every 30 days.

  • Auth declared10 pts

    Declare the credential headers in the registry entry, or keep the endpoint answering the probe so its auth can be classified.

  • Tools listed15 pts

    Answer tools/list without a credential, or ship a package that starts in a sandbox without one.
