Components

Tools

1. read-note: Retrieve the complete contents of the note by its ID from the database.
   • Required inputs:
     • noteId: The ID of the note to retrieve. It can be found as _id in the note docs. It always starts with note:.
   • Optional inputs:
     • includeTemplate: When true and the note has a sourceTemplateId, also fetch that template and embed its body (fill-out instructions and examples) as an extra text block. Default: false.
   • Note: If the note was created from a template, the response includes a resource link to its source template, whose body holds the fill-out instructions and examples.
2. read-backlinks: Retrieve backlinks for a note — the notes that link to it.
   • Required inputs:
     • noteId: The ID of the note to find backlinks for. It always starts with note:.
   • Note: Each result is returned as a resource link (inkdrop://note/<id>) pointing to the referring note. Backlinks are found by searching all note bodies for the note's link URI.
3. search-notes: List all notes that contain a given keyword.
   • Required inputs:
     • keyword: Keyword to search for.
   • Note: Results include truncated note bodies (200 characters). Use read-note to get full content.
   • Supports advanced search qualifiers like book:, tag:, status:, title:, etc.
4. list-notes: List all notes with specified conditions.
   • Required inputs:
     • bookId: The notebook ID. It always starts with 'book:'.
   • Optional inputs:
     • tagIds: An array of tag IDs to filter. Each starts with 'tag:'.
     • keyword: Keyword to filter notes.
     • sort: Sort field (updatedAt, createdAt, or title). Default: updatedAt.
     • descending: Reverse the order of output. Default: true.
   • Note: Results include truncated note bodies (200 characters). Use read-note to get full content.
5. create-note: Create a new note in the database.
   • Required inputs:
     • bookId: The notebook ID. Must start with 'book:' or be 'trash'.
     • title: The note title.
     • body: The content of the note in Markdown.
   • Optional inputs:
     • status: The note status (none, active, onHold, completed, dropped).
     • tags: An array of tag IDs to assign to the note. Each must start with 'tag:'.
6. update-note: Update an existing note in the database. Only the fields you provide will be updated; omitted fields remain unchanged.
   • Required inputs:
     • _id: The note ID. Must start with 'note:'.
     • _rev: The revision ID (CouchDB MVCC-token).
   • Optional inputs:
     • bookId: The notebook ID. Must start with 'book:' or be 'trash'.
     • title: The note title.
     • body: The content of the note in Markdown.
     • status: The note status (none, active, onHold, completed, dropped).
     • tags: An array of tag IDs to assign to the note. Each must start with 'tag:'.
7. patch-note: Update the body of an existing note by performing an exact string replacement. More efficient than update-note for small edits to large notes as it saves tokens. You must first read the note with read-note to get the current body.
   • Required inputs:
     • _id: The note ID. Must start with 'note:'.
     • _rev: The revision ID (CouchDB MVCC-token).
     • old_string: The exact text to find in the note body. Must match exactly one occurrence. Include enough surrounding context to ensure a unique match.
     • new_string: The text to replace old_string with. Use an empty string to delete the matched text.
8. list-notebooks: Retrieve a list of all notebooks.
9. read-book: Retrieve a single notebook by its ID.
   • Required inputs:
     • bookId: The notebook ID. Must start with 'book:'.

Debugging

Since MCP servers run over stdio, debugging can be challenging. For the best debugging experience, we strongly recommend using the MCP Inspector.

You can launch the MCP Inspector via npm with this command:

npx @modelcontextprotocol/inspector "./dist/index.js"

Be sure that environment variables are properly configured.

Upon launching, the Inspector will display a URL that you can access in your browser to begin debugging.

You can also watch the server logs with this command:

tail -n 20 -f ~/Library/Logs/Claude/mcp-server-inkdrop.log
