perf

perf is an MCP server for Claude Code, Codex, Cursor from rog0x/mcp-perf-tools. Its token cost is not measured, scanned A, original, no licence file.

A local code-analysis tool for benchmarking programs, checking memory use, and examining Big O, which describes how running time or memory grows as input gets larger.

In plain words
What is it for?
Use it to benchmark code, inspect memory consumption, and analyze algorithm complexity.
Why use it?
It helps identify slow code, excessive memory use, and poor growth behavior without relying only on guesses.

Security

Grade A, and why

perf 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 3d 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 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.

perf is an MCP server published in the GitHub repository rog0x/mcp-perf-tools (0 stars, last pushed 5mo ago), with no licence file. Its token cost is not measured: an MCP server costs its tool schemas, not its config file. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
