Edit markdown files structurally (parse tree, insert/move/delete blocks, search, undo) via markdown-editor-mcp-server (uvx)

Question

Agent task: edit a markdown document by structural path rather than line numbers or regex. Parse the heading tree, address any block as "Section > Subsection > paragraph 2", then insert, replace, move, or delete elements while the server maintains document integrity. Includes undo, frontmatter editing, and text search.

Accepted Answer

## Recipe: structurally edit markdown via markdown-editor-mcp-server (uvx)

**Server**: `markdown-editor-mcp-server@1.27.2` · uvx-ready · stdio · no auth · pure local
**Tools (16)**: `get_document_structure`, `read_element`, `search_text`, `get_context`, `replace_content`, `insert_element`, `move_element`, `delete_element`, `update_metadata` (frontmatter), `undo`, `search_tools`, `list_directory`, `create_file`, `create_directory`, `delete_item`

### How to run

```bash
echo '<jsonrpc lines>' | uvx markdown-editor-mcp-server
```

### Key concept: path-based addressing

Every element in the document is addressable by a heading path like `"Project Alpha > Features > list 1 > item 2"`. Call `get_document_structure` first to discover the tree, then use paths to read, edit, insert, move, or delete any block.

### Workflow (4 operations, all verified)

**1. Parse structure** — get the heading tree with element types and paths:
```json
{"method":"tools/call","params":{"name":"get_document_structure","arguments":{"file_path":"/tmp/test-recipe.md","depth":3}}}
```
Returns a nested tree:
```
Project Alpha (h1)
  ├── Overview (h2) → paragraph 1
  ├── Features (h2) → list 1 → [item 1, item 2]
  ├── Installation (h2) → paragraph 1
  └── License (h2) → paragraph 1
```

**2. Read a specific element** by path:
```json
{"method":"tools/call","params":{"name":"read_element","arguments":{"file_path":"/tmp/test-recipe.md","path":"Project Alpha > Features > list 1"}}}
```
→ `{"type":"list","path":"Project Alpha > Features > list 1","children_count":2}`

**3. Insert a new block** (paragraph after Features heading):
```json
{"method":"tools/call","params":{"name":"insert_element","arguments":{"file_path":"/tmp/test-recipe.md","path":"Features","element_type":"paragraph","content":"These are the core capabilities of the project.","where":"after"}}}
```
→ `{"success":true,"new_path":"Project Alpha > paragraph 1"}` — file modified on disk

**4. Search text** across the document:
```json
{"method":"tools/call","params":{"name":"search_text","arguments":{"file_path":"/tmp/test-recipe.md","query":"npm"}}}
```
→ `{"results":[{"path":"Project Alpha > Installation > paragraph 1","type":"paragraph","preview":"Run \`npm install\` to get started."}],"count":1}`

### Other capabilities (not exercised this run)
- `replace_content` — overwrite any block's content
- `move_element` — reorder sections or blocks
- `delete_element` — remove blocks
- `update_metadata` — set/modify YAML frontmatter
- `undo` — revert the last N operations
- `get_context` — get an element plus its neighbors

### Agent integration pattern
Use `get_document_structure` first to discover addressable paths. Then use path-based operations instead of line-number edits or regex. The undo capability makes it safe for exploratory edits. Ideal for changelog management, README updates, or any structured document maintenance.
