microsoft-planner-mcp: Instructions file for GitHub Copilot

.github/copilot-instructions.md

microsoft-planner-mcp copilot-instructions.md is an instructions file for GitHub Copilot from aixolotl/microsoft-planner-mcp. It costs 568 tokens per session, scanned A, original, MIT.

Repository instructions for a Microsoft Planner MCP server, a program that lets an AI assistant work with Microsoft Planner through the Model Context Protocol. They document the Python stack, project structure, authentication, services, tools, and testing setup.

In plain words
What is it for?
Use them when developing or maintaining the server, including its Azure Entra ID login flow, Microsoft Graph Planner operations, FastMCP tools, configuration, and automated tests.
Why use it?
They give coding agents the project’s required conventions and architecture before they make changes. This helps keep authentication, Graph API access, and tests consistent.

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

microsoft-planner-mcp copilot-instructions.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 1mo 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.

Microsoft Planner MCP — Copilot Instructions

Project Overview

MCP server for Microsoft Planner built with FastMCP and Microsoft Graph SDK. Authenticates via Azure Entra ID On-Behalf-Of flow.

Stack

  • Python 3.12+ with from __future__ import annotations in every module
  • FastMCP (fastmcp[apps]) — MCP server framework with routers, tools, and OAuth
  • Microsoft Graph SDK (msgraph-sdk) — Planner API via GraphServiceClient
  • Pydantic Settings — environment-based configuration
  • pytest + pytest-asyncio (auto mode) — testing
  • uv — package manager and task runner

Project Structure

  • src/ — application package
    • src/server.py — FastMCP app, middleware, route mounting
    • src/config.py — Settings via pydantic_settings.BaseSettings
    • src/auth_provider.py — Azure OAuth provider; optional encrypted Redis store for OAuth state (REDIS_URL)
    • src/deps.py — shared dependency helpers (e.g. get_optional_context())
    • src/graph_client_manager.py — singleton GraphClientManager with per-user OBO clients
    • src/types.py — shared structural types (e.g. CollectionRequestBuilder Protocol)
    • src/services/ — business logic wrapping Graph SDK calls
    • src/tools/ — FastMCP tool routers (one router per domain, mounted in server.py)
  • tests/ — unit tests mirroring src/ structure

Conventions

  • Tool routers live in src/tools/ as separate FastMCP instances mounted on the main app
  • Services in src/services/ accept a GraphServiceClient and encapsulate Graph API logic
  • All Graph calls use async with graph_client_manager.for_user(token) for OBO auth
  • Tools that require business logic instantiate the relevant service inside the async with block: service = PlannerService(graph_client)
  • Simple direct Graph reads (no pagination, no retry, no ETag) may call the SDK directly from the tool without a service
  • Tools must check get_access_token() and raise AuthorizationError when None
  • Use get_optional_context() from src.deps instead of raw try/except RuntimeError around get_context()
  • Run tests with uv run pytest -v
  • Run server with uv run uvicorn src.server:app --host 0.0.0.0 --port 8000 --reload

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.
