Overview

AI-generated overview

A local MCP server that lints Mermaid diagrams in LLM output, repairs unquoted brackets and normalizes syntax.

What you can do
  • Lint Mermaid diagram code found in Markdown or LLM output
  • Heal unquoted bracket syntax that breaks rendering
  • Normalize Mermaid syntax into a consistent form
  • Runs as a small local Python process with no external dependencies
When to use it
Useful when an assistant generates or edits Markdown containing Mermaid diagrams and you want them checked and repaired before rendering, especially when LLM output often produces broken diagram syntax.
Requirements
Runs locally over stdio as a Python 3 process started with mcp_server.py; the README states it uses only the Python standard library, so no extra packages, accounts, keys or network access are declared.
Before you install
It rewrites diagram source, so review healed output before committing it to documents; no credentials, payments or third-party data transfer are declared.

Installation

In SourceWeft

  1. Open GenPark Markdown Mermaid Syntax Lint Healer 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.

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.

  • 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.
