Safe YAML frontmatter parsing and AST-aware updates
Mcp Obsidian is categorized under Knowledge & Memory and uses a local stdio subprocess. In contrast, Markmap Mcp Server belongs to Knowledge & Memory using local stdio subprocess. Select Mcp Obsidian when you need capabilities focused on knowledge & memory and Markmap Mcp Server when you require tools for knowledge & memory.
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
Retrieve a generated mind map file by absolute path. Read-only — no side effects. Only paths inside the configured output directory are allowed (path traversal denied).
Returns JSON {"filePath","mimeType","size"}. For text/html or image/svg+xml under 200KB, also appends a text content block. PNG/JPG return metadata only (no image block) — re-export via markdown_to_mindmap with format=png|jpg if the agent needs pixels.
On error: isError:true with {"error":"Failed to retrieve mind map","message"}.
Use list_mindmaps first to obtain a valid filePath. Prefer this over regenerating when the file already exists.
cleanup_mindmaps
Permanently delete markmap* files from the output directory. DESTRUCTIVE and irreversible when dryRun is false.
dryRun defaults to false — omitting it WILL delete. Always call once with dryRun=true to preview, then again with dryRun=false to commit. Prefer list_mindmaps beforehand.
Returns {"deleted":["<path>",...],"kept":<n>}; dryRun responses also include dryRun:true and do not delete.
Use instead of manual file deletion when pruning old generated mind maps.
