What is mcp CLAUDE.md?

Repository instructions for gremlin/mcp, a project that works with Gremlin reliability tests—tests that deliberately check how systems handle failures.

Use it to decide how to work with uncommitted changes, inspect Gremlin API endpoints, build through the Makefile, and run the project’s tests.

It helps avoid unsafe work in an already changed branch and keeps API lookups, builds, and tests consistent.

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	$0.00176	$0.00176
Opus 5.5	$0.00070	$0.00070
Sonnet 5.5	$0.00035	$0.00035
Haiku 4.5	$0.00018	$0.00018

Security

Grade A, and why

mcp CLAUDE.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 2mo 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.

What it actually says

Planning If the branch is not clean at the start of a session ask if you should make the changes in the dirty environment or on a new branch

If you need information about gremlin endpoints you can fetch the swagger via:

curl 'https://api.gremlin.com/v1/openapi.json' | jq '.paths."/reliability-tests/{reliabilityTestId}/runs".post'

Or something similar

NOTE: The swagger endpoints are not prefixed with v1/ but the actual endpoints will be

Finally, do NOT load the entire openapi.json into your context window it's way too big

Tooling

Prefer build actions from the Makefile

Testing

the general test command is: env $(cat .env | xargs) make test 2>&1

Changes

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.
