Project instructions for tududi-mcp, a server that lets language-model clients access the Tududi productivity app through its API. Tududi must already be running and reachable.

In plain words
What is it for?
Use them when changing or reviewing this MCP server, especially its request endpoint, Tududi API client, configuration, modules, tools, or resources.
Why use it?
They give coding agents the project’s architecture, important files, authentication approach, and differences from typical Next.js projects.

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.

Security

Grade A, and why

tududi-mcp AGENTS.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

This is tududi-mcp — a whitelabel MCP (Model Context Protocol) server that bridges LLM clients to Tududi, an open-source GTD/productivity app created by Chris Vel.

The server does not include the Tududi application. A running, self-hosted Tududi instance with API access is required.

This is NOT the Next.js you know

APIs, conventions, and file structure may differ from training data. Read relevant guide in node_modules/next/dist/docs/ before writing code.

Architecture

The MCP endpoint lives at app/mcp/route.ts. It uses mcp-handler with withMcpAuth for per-request bearer token authentication against the Tududi /api/profile endpoint. On initialisation the server lazily loads 8 domain modules from lib/tududi/modules/ and registers 25 tools and 10 resources.

Key files

File Purpose
app/mcp/route.ts MCP entry point — creates handler, verifies token, exports route
lib/tududi/client.ts HTTP client wrapping Tududi REST API (GET/POST/PATCH/DELETE)
lib/tududi/config.ts Module names, config types, isModuleEnabled helper
lib/tududi/types.ts Shared TypeScript types
lib/tududi/modules/index.ts Lazy module registry — loads and registers tools/resources

Authentication flow

  1. MCP client sends tududi-api-url header + Authorization: Bearer <token>.
  2. app/mcp/route.ts verifyToken function calls GET /api/profile on the Tududi instance.
  3. On success, returns AuthInfo with the user's UID, email, API URL, and enabled modules.
  4. On failure, returns undefined → request is rejected.

Modules

Each module under lib/tududi/modules/<name>/ exports a register(server, client) function that registers its tools and resources with the MCP server.

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.
