What is mcp-todoist CLAUDE.md?

A set of project instructions for an AI coding assistant working on an MCP server that connects Todoist with AI tools. Todoist is a task and project management service, and MCP lets software call its functions.

It is for maintaining a Todoist integration that can create, read, update, complete, and organize tasks, projects, sections, and labels.

It tells the assistant how to build, run, debug, and watch the integration while supporting its different connection methods.

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	$0.01431	$0.01431
Opus 5	$0.00715	$0.00715
Sonnet 5	$0.00286	$0.00286
Haiku 4.5	$0.00143	$0.00143

Security

Grade A, and why

mcp-todoist 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 8d 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.

Architecture Overview

The project follows a clean modular architecture:

Core Components

src/index.ts: MCP server factory function and stdio compatibility. Exports createServer() for HTTP streaming and maintains main() for stdio transport. Handles server lifecycle, environment configuration, and graceful shutdown.
src/todoist/client.ts: Encapsulates all Todoist API interactions using the official @doist/todoist-api-typescript SDK. Implements centralized error handling and tool registration for 14 MCP tools.
src/todoist/types.ts: TypeScript type definitions and Zod schemas for Todoist API parameters and configuration.
