## Summary
This PR adds write capabilities to AFFiNE's MCP (Model Context Protocol)
integration, enabling external tools (Claude, GPT, etc.) to create and
modify documents programmatically.
**New MCP Tools:**
- `create_document` - Create new documents from markdown content
- `update_document` - Update document content using structural diffing
for minimal changes (preserves document history and enables real-time
collaboration)
**Implementation:**
- `markdown_to_ydoc.rs` - Converts markdown to AFFiNE-compatible y-octo
binary format
- `markdown_utils.rs` - Shared markdown parsing utilities (used by both
ydoc-to-md and md-to-ydoc)
- `update_ydoc.rs` - Structural diffing implementation for updating
existing documents
- `DocWriter` service - TypeScript service for document operations
- Exposes `markdownToDocBinary` and `updateDocBinary` via napi bindings
**Supported Markdown Elements:**
- Headings (H1-H6)
- Paragraphs
- Bullet lists and numbered lists
- Code blocks (with language detection)
- Blockquotes
- Horizontal dividers
- Todo items (checkboxes)
**y-octo Changes:**
This PR reverts the y-octo sync (ca2462f, a5b60cf) which introduced a
concurrency bug causing hangs when creating documents with many nested
block structures. It also ports the improved `get_node_index` binary
search fix from upstream that prevents divide-by-zero panics when
decoding documents.
## Test Results ✅
### Unit Tests (47/47 passing)
| Test Suite | Tests | Status |
|------------|-------|--------|
| markdown_to_ydoc | 16/16 | ✅ Pass |
| markdown_utils | 11/11 | ✅ Pass |
| update_ydoc | 13/13 | ✅ Pass |
| delta_markdown | 2/2 | ✅ Pass |
| affine (doc parser) | 5/5 | ✅ Pass |
### End-to-End MCP Testing ✅
Tested against local AFFiNE server with real MCP client requests:
| Tool | Result | Notes |
|------|--------|-------|
| `tools/list` | ✅ Pass | Returns all 5 tools with correct schemas |
| `create_document` | ✅ Pass | Successfully created test documents |
| `update_document` | ✅ Pass | Successfully updated documents with
structural diffing |
| `read_document` | ✅ Pass | Existing tool, works correctly |
| `keyword_search` | ✅ Pass | Existing tool, works correctly |
**E2E Test Details:**
- Started local AFFiNE server with PostgreSQL, Redis, and Manticore
- Created test user and workspace via seed/GraphQL
- Verified MCP endpoint at `/api/workspaces/:workspaceId/mcp`
- Tested JSON-RPC calls with proper SSE streaming
- Confirmed documents are stored and indexed correctly (verified via
server logs)
## Test Plan
- [x] All Rust unit tests pass (47 tests)
- [x] Native bindings build successfully (release mode)
- [x] Document creation via MCP works end-to-end
- [x] Document update via MCP works end-to-end
- [x] CodeRabbit feedback addressed
- [ ] Integration testing with Claude/GPT MCP clients
Closes#14161

efficiency)
