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 | $0.03408 | $0.03408 |
| Opus 5.5 | $0.01363 | $0.01363 |
| Sonnet 5.5 | $0.00682 | $0.00682 |
| Haiku 4.5 | $0.00341 | $0.00341 |
Grade A, and why
ms-graph-mcp 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 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.
How it starts
The opening of the file, as written. The whole thing — 221 lines — stays where its author put it; the contents beside it link to each section on GitHub.
CLAUDE.md
Guidance for Claude Code working in this repository.
ms-graph-mcp is a Model Context Protocol server for Microsoft Graph — 85 tools across calendar,
email, meetings, Teams chat, files, people, contacts, directory, tasks, OneNote and
search, served over stdio or Streamable HTTP. Tool names are namespaced by Graph permission family (mail_, files_,
calendar_, meetings_, chat_, directory_, people_, tasks_, notes_, search_).
The Graph client is raw httpx2 by design: msgraph-sdk and azure-identity are
deliberately not dependencies (see the note at the bottom of the dependencies block in
pyproject.toml, and ADR 0002).
README.md covers the user-facing surface — install, transports, env vars, headers. This file covers the invariants a change has to respect.
Commits
Commits use the git user configured on the machine (git config user.name / user.email) and carry
no tool attribution: no Co-Authored-By: Claude … trailer, no Claude-Session: line, and no
"Generated with Claude Code" footer in PR bodies. This is a public MIT project — the history is part
of its face. Write the subject and body, then stop.
Commands
uv sync # install (uv only — no pip/poetry)
uv run pytest -q # full suite
uv run pytest tests/test_meetings.py -q # one file
uv run pytest -k "write_scope" -q # one test
uv run ruff check . # NB: [tool.ruff] fix = true — this rewrites files
uv run ruff format . # CI runs --check; keep the tree formatted
tests/test_protocol_conformance.py drives a real mcp.Client session against the server
in-process. That is the only place the wire protocol is actually exercised — the other tests call
handlers directly, which cannot catch a schema rejection or a silent downgrade to the legacy
protocol revision.
asyncio_mode = "auto", so async tests need no @pytest.mark.asyncio. --import-mode=importlib is
what lets tests/test_config.py and tests/entra/test_config.py coexist without __init__.py.
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.

ms-graph-mcp CLAUDE.md is an instructions file published in the GitHub repository nitin27may/ms-graph-mcp (3 stars, last pushed 24d ago), licensed MIT. It adds 3,408 tokens to every session, about $0.0136 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
