Todoist + Telemetry Logging

August 31, 2025 AImcptech

A remote, GitHub-OAuth-protected MCP server that gives any agent secure read/write access to my Todoist — and quietly logs every tool call so the AI can answer “how much time did you save me?” Two surfaces in one server: a Todoist control plane and an AI-usage observability plane. Live on Cloudflare’s edge since September 2025.

Details

• Live — Cloudflare Workers
• Stack — Cloudflare Workers + Durable Objects + D1 + KV
• Auth — GitHub OAuth (per-user approval, not a shared API key)
• SDK — @modelcontextprotocol/sdk, @cloudflare/workers-oauth-provider

Why it matters

Quantifies the AI’s actual impact — every tool call lands in D1 with a configurable time-saved weight, so the server can answer “how much time did you save me this month?” with real numbers. Most MCP servers expose data; this one also measures itself.
