Zed Agentic Mermaid render_ascii

How to: Zed Agentic Mermaid render_ascii

client:Zed transport:streamable-http tool:render_ascii

Add Agentic Mermaid to Zed

  1. 01

    Open ~/.config/zed/settings.json and merge this in. Keep any servers already there.

{
  "context_servers": {
    "agentic-mermaid": {
      "url": "https://agentic-mermaid.dev/mcp"
    }
  }
}
  1. 02

    Save the file and restart Zed.

  2. 03

    Ask for something render_ascii does. Zed lists the server's tools on connect and calls render_ascii itself — you do not invoke it by name.

  3. 04

    If nothing happens, check the server is running and that Agentic Mermaid's identifier in your config matches the one above exactly.

Merge this into your existing settings object — do not replace the file. Zed docs

Same tool, other clients

This list was read from the server itself, by connecting to it and calling tools/list on 24 September 2026. It is what the server actually exposes, not what its listing claims.

Mutating and Read-only are read off each tool's name, not its schema — a hint, not a guarantee. The registry stores tool names only; connect the server for its live schemas.
