A set of AGENTS.md instructions for developing an MCP server, a program that lets an AI coding assistant use external tools.

In plain words
What is it for?
It is for guiding work on the fips-agents/mcp-server-template project, including tool planning and implementation.
Why use it?
It gives contributors a suggested workflow so they can plan the server's tools before creating them.

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.

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 B, and why

mcp-server-template AGENTS.md scanned grade B with 2 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 2d 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.

Asks for rootmediumPrivilege escalation

A mod that escalates privileges can change anything on the machine, not only the project.

1. Fix permissions: `find src -name "*.py" -perm 600 -exec chmod 644 {} \;`

Makes network callslowCapability

Not a fault in itself. Listed so you know the mod talks to something, and to what.

* If I give you an MCP server URL to use with an agent, do not try to test the MCP server yourself. Just use it with the agent and let the agent discover its tools. This is different from a REST API where I would want yo

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.
