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 | $0.02809 | $0.02809 |
| Opus 5.5 | $0.01124 | $0.01124 |
| Sonnet 5.5 | $0.00562 | $0.00562 |
| Haiku 4.5 | $0.00281 | $0.00281 |
Grade A, and why
teams-mcp-server 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 14d 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.
This is a copy
100% identical to teams-mcp-server CLAUDE.md — 123 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts
The opening of the file, as written. The whole thing — 123 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Teams MCP Server
MCP server for Microsoft Teams via Microsoft Graph API. Delegated auth (device code flow), no client secret.
Stack
Python per requires-python in pyproject.toml (the latest stable release; dev pin in .python-version), mcp[cli] 2.x (MCPServer; the major is bounded <3, so the next SDK major is a deliberate port rather than a broken fresh install), httpx, msal. Tests in tests/ (uv run pytest): test_server.py pins the tool surface and formatting, test_tools.py calls tools through an in-process mcp.Client over a fake Graph transport (httpx.MockTransport) and fake sign-in, with no network; ruff + pytest in the dev group (uv sync). CI runs on push/PR via .github/workflows/ci.yml (uv sync + pytest + advisory ruff).
Commands
uv run teams-mcp # run server (needs TEAMS_MCP_TENANT_ID, TEAMS_MCP_CLIENT_ID)
uv run teams-mcp login # device code sign-in in the terminal (same variables)
Environment Variables
TEAMS_MCP_TENANT_ID(required) - Azure AD tenant IDTEAMS_MCP_CLIENT_ID(required) - App registration client IDTEAMS_MCP_SCOPES(optional) - comma-separated scope override (default:.default; scope semantics in the Scopes section)
Architecture
Three-file pattern, all logic flows through the same pipeline:
server.py (MCP tools) -> graph.py (Graph API client) -> Microsoft Graph REST API
auth.py (MSAL device code flow, token cache)

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.
