Feature & Specification Comparison
Tools & Capabilities Breakdown
Markmap MCP Server Tools (4)
markdown_to_mindmap
Convert structured Markdown (headings # and nested lists -) into an interactive mind map HTML file, with optional server-side PNG/JPG/SVG export.
Use when the user wants a visual mind map/outline of structured content (architecture, plans, notes, hierarchies), or asks to visualize / mindmap / diagram. Do not use for flat unstructured text (restructure first), or to list/read existing outputs (use list_mindmaps / get_mindmap).
Behavior:
- WRITES files under the configured output dir. HTML is always written; image formats write an extra file. Reusing filename overwrites.
- html is fast (<1s). png/svg/jpg launch headless Chromium via Playwright (5–15s; requires: npm install playwright && npx playwright install chromium).
- Local only — no external APIs or third-party keys. Open mode=never: The server never opens the browser.
- Offline=false (server config).
Response:
- JSON {"htmlFilePath":"<path>","filePath":"<path>"} — htmlFilePath is always the HTML source; filePath is the primary artifact (HTML or image).
- Return mode=path: Paths JSON only — no inline content.
- Errors: isError:true with {"error","message"}.
list_mindmaps
List markmap* files (html/png/jpg/jpeg/svg) in the output directory, newest first. Read-only — no side effects. Missing/empty dirs return {"files":[]}.
Returns: {"outputDir","files":[{"name","filePath","size","mtimeMs","mtime"}]} (mtime is ISO 8601).
Use before get_mindmap to discover paths, or before cleanup_mindmaps to preview targets. Not for generating new mind maps (use markdown_to_mindmap).
get_mindmap
Ready-to-Paste Client Configurations
Paste either (or both) of these JSON server blocks into your client config file (e.g. claude_desktop_config.json or ~/.cursor/mcp.json).
