Local todo list MCP server. Exposes 7 tools to LLMs/agents: batch write, list, update, delete, notes, incremental sync. Built on Go + SQLite, single-binary deploy, safe for concurrent multi-agent use.

Design doc: DESIGN.md. Agent usage guide: skill/SKILL.md.

• MCP stdio: drop-in for Claude Desktop / Cursor / any MCP client
• 7 tools: todo_write / todo_list / todo_update / todo_delete / todo_add_note / todo_get_notes / todo_diff
• Context compression: compact view drops metadata + relative time; todo_diff for incremental sync instead of full list
• Concurrent multi-agent: SQLite WAL + IMMEDIATE transactions, cross-process safe
• Short IDs: t1 / t3a instead of UUIDs, saves tokens
• Markdown / plain text auto-detected, indentation expresses parent/child

git clone https://github.com/sumingcheng/tido.git
cd tido
make install   # builds and installs to ~/.local/bin/tido

Or just build:

make build     # outputs ./bin/tido

Requires Go 1.25+. SQLite uses pure-Go driver modernc.org/sqlite; no CGO needed.

A single binary supports two transports:

DB defaults to ~/.tido/todos.db; override with TIDO_HOME.

Claude Desktop / Cursor MCP config:

{
  "mcpServers": {
    "tido": { "command": "/path/to/tido" }
  }
}

cp .env.example .env
# Edit .env: set TIDO_TOKEN to a strong random string (openssl rand -hex 32)
make docker-up         # docker-compose up -d
make docker-logs       # tail startup logs

Image is ~14 MB (distroless static + statically linked Go binary), runs as nonroot, DB stored in named volume tido_tido-data.

Cursor config switched to HTTP transport:

{
  "mcpServers": {
    "tido": {
      "url": "http://127.0.0.1:18080/mcp",
      "headers": { "Authorization": "Bearer <your TIDO_TOKEN>" }
    }
  }
}

If port 18080 is taken, set TIDO_PORT in .env and update the Cursor URL accordingly.

Don't open 0.0.0.0 just so neighbor containers can reach tido. Use a shared docker network instead — zero exposure to the host network:

# one-time on the host
docker network create mcp-net

tido's compose already joins mcp-net (declared as external). Make any other compose project join the same network:

services:
  your-service:
    networks: [default, mcp-net]

networks:
  mcp-net:
    external: true
    name: mcp-net

Then from inside that container call http://tido:8080/mcp (container name as DNS, container-internal port 8080 — not the host's 18080).

docker run --rm -v tido_tido-data:/data -v $PWD:/backup alpine \
  tar czf /backup/tido-$(date +%F).tgz -C /data .

• HTTP mode refuses to start if TIDO_TOKEN is empty (prevents accidental public exposure)
• Default binds 127.0.0.1 only; never directly exposed to the public internet
• For remote access: put it on Tailscale/WireGuard, or front it with caddy/nginx for TLS

echo '{"jsonrpc":"2.0","id":1,"method":"initialize","params":{"protocolVersion":"2024-11-05","capabilities":{},"clientInfo":{"name":"x","version":"0"}}}
{"jsonrpc":"2.0","method":"notifications/initialized","params":{}}
{"jsonrpc":"2.0","id":2,"method":"tools/list","params":{}}' | tido

You should see 8 tools (ping + 7 todo tools).

make test            # full unit + integration tests (with -race)

make fmt vet tidy    # gofmt / go vet / go mod tidy
