What is whoop-mcp CLAUDE.md?

Project instructions for whoop-mcp, a local server that lets Claude Code read and update data through the Whoop fitness service.

Working on the whoop-mcp codebase, running its tests, logging in, checking authentication, and understanding its read and write operations.

They give the agent the project layout, commands, tests, authentication steps, and available tools in one place.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00533	$0.00533
Opus 5	$0.00267	$0.00267
Sonnet 5	$0.00107	$0.00107
Haiku 4.5	$0.00053	$0.00053

Security

Grade A, and why

whoop-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 9d 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.

The opening of the file, as written. The whole thing — 60 lines — stays where its author put it; the contents beside it link to each section on GitHub.

whoop-mcp

MCP server for Whoop. Wraps whoop-write-api as tools for Claude.

Architecture

Claude Code <--stdio--> whoop-mcp <--https--> Whoop API
                            |
                      ~/.whoop/tokens.json

Commands

.venv/bin/pytest -x --tb=short              # run tests
.venv/bin/whoop-write-mcp login             # authenticate with whoop
.venv/bin/whoop-write-mcp status            # check auth state
.venv/bin/whoop-write-mcp                   # run server (stdio)

Directory Layout

src/whoop_write_mcp/ — package source
- server.py — FastMCP app, tool registration
- cli.py — CLI entry point (login, status, logout)
- tools_read.py — read tool handlers (recovery, sleep, strain, body, catalog, journal behaviors)
- tools_write.py — write tool handlers (activities, workouts, exercises, journal, weight, alarm)
- auth.py — token persistence and refresh
tests/ — pytest suite
- test_tools_read.py — read handler tests
- test_tools_write.py — write handler tests
- test_auth.py — auth tests

Tools (15 total)

Read tools: get_recovery, get_sleep, get_strain, get_body_measurement, get_sport_types, search_exercises, get_journal_behaviors

Write tools: create_activity, delete_activity, list_activities, log_workout, link_exercises, log_journal, update_weight, set_alarm

Key Patterns

all whoop imports are lazy (inside functions)
tools return dicts, server.py json-serializes them
JSON string params for complex inputs (exercises, journal entries) with error handling
auth tokens stored at ~/.whoop/tokens.json (0600 perms)
auto-refresh on expired access token
transport: stdio only (for Claude Code subprocess)

Dependencies

mcp[cli] — MCP Python SDK with FastMCP
whoop-write-api — reverse-engineered Whoop API client
pydantic — input validation

Testing

mock whoop client in all tests, never hit real API
patch at whoop_write_mcp.auth.get_whoop_client (lazy import source)

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.
