testmcp: Instructions file for Claude Code

CLAUDE.md

testmcp CLAUDE.md is an instructions file for Claude Code from r-marques/testmcp. It costs 1,191 tokens per session, scanned A, original, no licence file.

A set of instructions for the testmcp project, covering its purpose, commands, architecture, and MCP tools. MCP is a way for an AI coding assistant to use connected tools.

In plain words
What is it for?
It is for guiding Claude Code while working on the r-marques/testmcp repository.
Why use it?
It gives an assistant project-specific context instead of relying only on general coding assumptions. The description does not provide the project's actual commands or architecture.

Instructions file for Claude Code

Written for Claude Code: the file is CLAUDE.md.

This is r-marques/testmcp's own configuration. It tells Claude Code how to work on testmcp itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything testmcp configures →

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.

Security

Grade A, and why

testmcp 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.

Runs shell commandslowCapability

Expected in a hook, worth knowing in a rule or an instructions file.

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.
