Overview

AI-generated overview

A local MCP server that gives an assistant open-source license metadata and license compatibility checks.

What you can do
Look up open-source license metadata and check compatibility between licenses through the server's tools, which are not itemized in the listing. Optionally fetch a remote license snapshot, or skip remote fetching with a local-only setting. Point the server at an alternative snapshot URL when needed.
When to use it
Useful when reviewing dependencies or projects for open-source licensing questions and wanting an assistant to check whether licenses are compatible, without leaving the conversation.
Requirements
Runs as a local process via the npm package @weiseer/license-checker-mcp over stdio. No authentication is declared. Network access may be used for the remote license snapshot unless LIC_LOCAL_ONLY is set; LIC_URL can override the snapshot URL.
Before you install
The server can fetch a remote license snapshot, so license data may come from a third party; set LIC_LOCAL_ONLY to avoid remote fetching. Changing LIC_URL points it at a different source, which affects the accuracy of results. No tools are listed, so verify behavior before relying on its checks.

Installation

In SourceWeft

  1. Open license-checker 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.

Why use this instead of your agent doing it itself

The DIY cost in token-spend, latency, and rate-limit risk is 100-1500x our cost. See the weiseer organization README for the economic argument.

Environment

Score

40% 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.

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

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