Matches of fixed checks, with the text they matched.

    The server marks "open_template" read-only (readOnlyHint: true), and its own name, description or input give the class "write".

    Matched text

    annotations: {"readOnlyHint":true,"destructiveHint":false,"idempotentHint":true,"openWorldHint":false}; The name "open_template" says "open": a word for a change.

    • The input takes a statement or command to run (input.code), which can change anything it can reach.
    Description, as the server wrote it
    Turn source code (C, C++, Java, Python or JavaScript, up to 80 lines) into a lab-record style flowchart where every box is linked to its code lines, plus a step-by-step dry run for a sample input (current line, box and variables at each step). Returns a link that opens it ready to play (▶ Explain), the program output and Mermaid code. Uses 1 AI credit.

    Description, as the server wrote it
    Create a diagram in AI Flowchart from a plain-English description and get a link that opens it as an editable board (edit, present as an animated slideshow, export PNG/PDF/PowerPoint). Flowcharts, sequence diagrams and mind maps also come back as Mermaid code. Types: flowchart, mindmap, sequence (API / login flows), erdiagram (database), systemdesign (architecture), swimlane, bpmn (BPMN 2.0 business process), orgchart, uml_class, uml_usecase, uml_state, uml_activity, timeline, gantt (project plan), chart (bar/line/pie… from data you describe). Uses 1 AI credit; advanced types need AI Flowchart Pro.

    • The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

This is not a safety rating, and no finding is not a safety guarantee. The groups and findings come from fixed checks of the tool definitions the server returned on the date shown, not from its code or what it does when called. How the checks work.

Install

Pinned to version 1.0.0. Values in angle brackets are yours to fill in.

claude mcp add --transport http diagrams https://mcp.aiflowchart.io/mcp --header 'Authorization: <your-authorization>'

Run in a terminal.

Claude Code permissions

Allow the reads, ask before a change, deny the deletes. Paste into .claude/settings.json.

.claude/settings.json
{
  "permissions": {
    "allow": [
      "mcp__diagrams__list_templates"

    ],

}

Tools that only read are allowed, tools that change things ask first, tools that delete or cancel are denied. It assumes the server is installed as diagrams. Review it before you use it.
