What is mcp AGENTS.md?

Repository instructions for the contributte/mcp project. They set a code-style rule to avoid temporary variables when a property can be accessed directly.

Use them when reviewing or writing code that reads nested object properties, creating temporary variables only when reuse or clarity makes them worthwhile.

They help keep changes concise and prevent unnecessary intermediate values in the code.

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	$0.00145	$0.00145
Opus 5.5	$0.00058	$0.00058

Security

Grade A, and why

mcp AGENTS.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 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.

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.

What it actually says

Agent Instructions

Code Style

Avoid Unnecessary Variables

Do not introduce unnecessary intermediate variables when accessing object properties. Access properties directly using chain notation.

Bad:

$sessionConfig = $serverConfig->session;
$type = $sessionConfig->type;
$ttl = $sessionConfig->ttl;

Good:

$type = $serverConfig->session->type;
$ttl = $serverConfig->session->ttl;

Only create intermediate variables when:

The same property chain is accessed many times (3+) and readability improves
The intermediate value needs to be modified
The property access has side effects that should only happen once

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.
