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

teams-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 5d 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.

Copilot Instructions — teams-mcp

Architecture

This is an MCP (Model Context Protocol) server that bridges AI assistants to Microsoft Graph APIs for Teams, chats, users, and search. It runs as a CLI tool (npx @ritchy-eu/teams-mcp@latest) over stdio transport.

Key components

  • src/index.ts — Entry point. Dual-mode: CLI commands (authenticate, check, logout) and MCP server mode (default). Registers all tool modules against a single McpServer instance.
  • src/services/graph.ts — GraphService singleton. Manages Microsoft Graph client initialization from a stored OAuth token (~/.msgraph-mcp-auth.json). All Graph API calls flow through graphService.getClient().
  • src/tools/*.ts — Tool registration modules (auth, chats, search, teams, users). Each exports a register*Tools(server, graphService) function that calls server.tool() with Zod schemas for input validation.
  • src/types/graph.ts — Re-exports @microsoft/microsoft-graph-types and defines custom response/summary interfaces (GraphApiResponse<T>, *Summary types). All API response shapes live here.
  • src/utils/ — Shared helpers: markdown.ts (markdown→sanitized HTML via marked+DOMPurify), attachments.ts (image hosted content uploads), users.ts (@mention parsing and user lookup).

Data flow

AI Assistant → stdio → McpServer → register*Tools handler → GraphService.getClient() → Microsoft Graph API

Development

npm run build          # Clean + tsc compile
npm run dev            # Watch mode (node --watch)
npm test               # vitest run
npm run test:watch     # vitest interactive
npm run test:coverage  # vitest with v8 coverage (80% threshold on all metrics)
npm run lint           # biome check
npm run lint:fix       # biome check --write --unsafe

TypeScript & Module Conventions

  • ESM-only ("type": "module" in package.json). Use .js extensions in import paths (TypeScript moduleResolution: "bundler").
  • Strict mode enabled with noUnusedLocals, noUnusedParameters, exactOptionalPropertyTypes, noImplicitOverride.
  • Prefix unused catch variables with underscore: catch (_error).
  • Linting/formatting via Biome (not ESLint/Prettier). Use node: protocol for Node.js built-in imports.

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.
