foldnotes-mcp 2.2.0

MCP server exposing the FoldNotes CLI (fn) as tools for Claude Desktop, Claude Code, and other MCP clients.

FoldNotes MCP Server

A Model Context Protocol server that exposes the FoldNotes command-line tool (fn) as tools any MCP-compatible client can call — Claude Desktop, Claude Code, or third-party clients. It's a thin, read/write bridge to your FoldNotes collection: everything the CLI can do, an AI assistant can do — under the same licensing and safety limits.

Made by Foldsoft Pty Ltd · foldnotes.io

Source-available, install-only. This repository is published so you can install and run the server — we don't accept code contributions. Questions, tips, and bug reports are welcome in Discussions; see CONTRIBUTING for direct support and security reporting.

Requirements

• macOS with the FoldNotes app, and the fn CLI installed from the app: FoldNotes → Install Command Line Tool. The server shells out to fn.
• Python 3.10+.

Install

git clone https://github.com/Foldsoft/foldnotes-mcp.git
cd foldnotes-mcp/python-sdk
python3 -m venv venv
source venv/bin/activate
pip install mcp

Verify:

fn version                 # confirm the CLI is on your PATH
python3 foldnotes_mcp.py   # starts the server on stdio — Ctrl-C to stop

The server auto-discovers fn at /usr/local/bin/fn or /opt/homebrew/bin/fn, falling back to fn on your PATH.

Connect to Claude Desktop

Add a foldnotes entry to ~/Library/Application Support/Claude/claude_desktop_config.json (absolute paths to the venv's Python and the server script):

{
  "mcpServers": {
    "foldnotes": {
      "command": "/absolute/path/to/foldnotes-mcp/python-sdk/venv/bin/python3",
      "args": ["/absolute/path/to/foldnotes-mcp/python-sdk/foldnotes_mcp.py"]
    }
  }
}

Restart Claude Desktop; the FoldNotes tools appear under the tools menu.

Connect to Claude Code

claude mcp add foldnotes -- \
  /absolute/path/to/foldnotes-mcp/python-sdk/venv/bin/python3 \
  /absolute/path/to/foldnotes-mcp/python-sdk/foldnotes_mcp.py

Add --scope user for all projects, or --scope project to share a .mcp.json. Confirm with claude mcp list or /mcp inside a session.

What it exposes

40+ tools covering notes, tasks, tags, backlinks, daily notes, properties/schema, saved queries, templates, projects, attachments, collections, and search. The full, always-current list is in the docs: foldnotes.io → AI & Automation.

Two safety rules are built in:

• Reading is free; writing needs a licence. Read tools always work; write tools and bind require a valid FoldNotes licence or active trial, otherwise they change nothing.
• Trash is human-owned. The server can move a note to the trash and restore it, but cannot empty the trash or permanently delete — that stays a deliberate, human-only action in the app.

Questions & support

• Setup help, usage questions, bugs, tips → Discussions.
• Direct support → [e-mail].
• Security → report privately via the repo's Security → Report a vulnerability. We don't use Issues or accept pull requests — see CONTRIBUTING.
