Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00532 | $0.00532 |
| Opus 5 | $0.00266 | $0.00266 |
| Sonnet 5 | $0.00106 | $0.00106 |
| Haiku 4.5 | $0.00053 | $0.00053 |
Grade A, and why
testmo-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 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.

Commands
# Install dependencies
uv sync
# Run the MCP server directly
uv run testmo-mcp.py
# Run via MCP CLI (for testing tools interactively)
uv run mcp dev testmo-mcp.py
Environment
Requires TESTMO_URL and TESTMO_API_KEY in .env (auto-loaded via python-dotenv).
Architecture
testmo-mcp.py is a thin entry point that imports the testmo/ package and runs the server. Tools are split into domain modules under testmo/tools/. 45 MCP tools total. Runs over stdio transport.
Package layout
testmo/
server.py # FastMCP instance + load_dotenv
config.py # Constants (timeouts, limits) + FIELD_MAPPINGS
client.py # _request() and _upload() HTTP helpers
tools/
projects.py # list_projects, get_project
folders.py # CRUD + find_folder_by_name; exports _get_all_folders helper
milestones.py # list_milestones, get_milestone
cases.py # CRUD + batch + search (11 tools)
runs.py # list_runs, get_run, list_run_results
attachments.py # list/upload/delete case attachments (4 tools)
automation.py # Sources + runs + threads (9 tools)
issues.py # list/get issue connections
composite.py # Recursive folder/case ops + advanced search (3 tools)
utility.py # get_field_mappings, get_web_url
HTTP Client
_request() for JSON API calls, _upload() for multipart uploads. Each call creates a fresh httpx.AsyncClient (no persistent connection).
Tool naming
All tools are prefixed testmo_ and use snake_case matching the Testmo API resource (e.g. testmo_list_cases, testmo_batch_update_cases).
Pagination & rate limiting
Auto-pagination helpers (e.g. _get_all_folders, testmo_get_all_cases) loop through pages with a 0.5s delay between requests. Batch operations (create/delete) auto-chunk at 100 items per request.

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.

testmo-mcp CLAUDE.md is an instructions file published in the GitHub repository strelec00/testmo-mcp (1 stars, last pushed 4mo ago), licensed MIT. It adds 532 tokens to every session, about $0.0027 per session on Opus 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.
