What is fitnesse-mcp AGENTS.md?

Repository instructions for coding agents working on fitnesse-mcp, a Python server that exposes FitNesse testing services as tools. They document the project layout, supported versions, commands, and special requirements for its debugging tools.

Use them to install the project, run its tests, understand its server and test files, and maintain its FitNesse tool integrations.

They prevent mistakes caused by changing pinned dependencies, using the wrong FitNesse version, or forgetting to regenerate tool documentation after a change.

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	$0.01037	$0.01037
Opus 5.5	$0.00415	$0.00415

Security

Grade A, and why

fitnesse-mcp AGENTS.md scanned grade A with 1 finding 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 today.

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.

What this is

fitnesse-mcp is a FastMCP server that exposes FitNesse's REST responders as MCP tools. The whole server is one module, server.py; the tests are in tests/.

FastMCP is pinned exactly (fastmcp==4.1.6 in pyproject.toml): it has broken things in minor releases. Bump it only on purpose and run the full test suite after.
Python 3.12+; CI tests 3.12 and 3.13.
The KDTA debug tools (fitnesse_debug_*, fitnesse_table_*) need netcare's FitNesse fork, which adds the debugTest/debugTable responders. A plain FitNesse does not have them. Features of newer forks get a fallback for older ones (look for "older fork" / "mod #…" in server.py).

Commands

pip install -e ".[dev]"
pytest                              # the whole suite, ~40 s
pytest tests/test_debug.py -q       # debug tools only
python scripts/tools_list.py        # regenerate docs/tools.md after changing any tool

tests/test_tools_doc.py fails while docs/tools.md does not match the tools.

How the code is organised

Configuration is read at import. FITNESSE_TOOLSETS is required and decides which tools exist. Tests that need other settings set the environment and importlib.reload(server) (see _reload and the debug_env fixture in tests/test_debug.py; tests/conftest.py sets the default all).
Tool visibility goes by tags. Each tool has one mode tag (read, write, test) and optionally an area (debug, complete). Extra env gates (FITNESSE_FILES_ROOT, FITNESSE_ALLOW_SHUTDOWN, FITNESSE_ALLOW_ACCOUNT_ADMIN) hide tools completely.
Debug session state lives in _DebugState, per FitNesse login and URL (headers auth mode lets each HTTP request bring its own). It is in memory only.
HTTP to FitNesse goes through urllib; tests replace it with fakes that record requests and return canned answers. No test needs a running FitNesse.

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.
