What is mcp_todo CLAUDE.md?

A project-instruction file for working on mcp_todo, a Git-based todo server with a web Kanban board. It records the project's purpose, setup commands, build steps, and testing information.

Use it when developing or maintaining the MCP server, its Express API, or its Svelte web interface.

It gives a coding agent the repository context and common commands needed to install, build, run, and test the project.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.03179	$0.03179
Opus 5.5	$0.01272	$0.01272
Sonnet 5.5	$0.00636	$0.00636
Haiku 4.5	$0.00318	$0.00318

Security

Grade A, and why

mcp_todo CLAUDE.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Project Overview

Git-Based MCP Todo Server - A fully implemented Model Context Protocol server for managing todos with Git version control. The project includes:

Complete MCP server for Claude Desktop and Claude Code integration
Full-stack web-based Kanban board with Svelte 5 frontend (with full CRUD operations)
Express API server bridging web UI and MCP server
Comprehensive test coverage (~94% backend, 100% store tests - component tests excluded due to Svelte 5 runes limitation)

Development Commands

# Install dependencies
npm install                     # Backend dependencies
cd web && npm install          # Frontend dependencies

# Build
npm run build                  # Build MCP server

# Run MCP server (for Claude Desktop/Code)
npm start                      # Start MCP server

# Run API server + Web UI
npm run dev:api                # Start API server in watch mode
cd web && npm run dev          # Start Vite dev server

# Or run both concurrently
npm run dev                    # Runs both API server and MCP server

# Run tests
npm test                       # All tests
npm run test:unit              # Unit tests
npm run test:integration       # Integration tests
npm run test:api               # API server tests
cd web && npm test             # Frontend tests

Architecture

The project has two main interfaces:

1. MCP Interface (Claude Desktop/Claude Code)

Claude Desktop ←→ MCP Server (stdio) ←→ TodoRepository ←→ GitManager ←→ Git Repo

Layers:

MCP Server (src/index.ts, src/server/MCPServer.ts) - Handles MCP protocol via stdio
TodoRepository (src/data/TodoRepository.ts) - Todo CRUD operations
GitManager (src/git/GitManager.ts) - Git operations and commits
ConflictResolver (src/git/ConflictResolver.ts) - Last-Write-Wins merge strategy
SyncManager (src/git/SyncManager.ts) - Auto-sync with remote repository

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
