MOST DANGEROUS TOOLS

High Risk

The most dangerous Obsidian Markdown Lint tools

Execute · Medium render_mermaid_diagrams Rendering Mermaid diagrams involves executing a diagram-rendering engine (e.g., mermaid-js) against code blocks extracted from markdown.

1 of Obsidian Markdown Lint's 4 tools can modify, destroy, or commit something on every call — and an agent calls them with no built-in limits.

POLICY

How to control Obsidian Markdown Lint

PolicyLayer is an MCP gateway — it sits between your AI agents and Obsidian Markdown Lint, and nothing reaches the server without passing your rules. These are the rules we recommend:

Cap read operations

{
  "extract_mermaid_from_svg": {
    "limits": [
      {
        "counter": "extract_mermaid_from_svg_per_minute",
        "window": "minute",
        "max": 60,
        "scope": "grant"
      }
    ]
  }
}

Controls API costs and prevents retry loops from exhausting upstream rate limits.

Create a free account and register Obsidian Markdown Lint — nothing to install.
Add these rules — paste them, or build them visually. Tune the limits to your setup.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.

How do I enforce a policy on Obsidian Markdown Lint? +
