assay-mcp-server

assay-mcp-server is an MCP server for Claude Code, Codex, Cursor, Gemini CLI, OpenCode from Rul1an/assay. Its token cost is not measured, scanned A, original, MIT.

An MCP server named assay, configured to launch from a downloaded release file. MCP is a standard way for an AI coding tool to connect to external tools and data.

In plain words
What is it for?
Use it when this server is installed and its available assay tools are documented; the input does not identify concrete tasks beyond running the server.
Why use it?
The input only describes how the server is launched, not what tools or evidence it provides. Its practical benefit therefore cannot be stated more specifically.

Written for no agent in particular: it speaks MCP, so any client can run it.

Security

Grade A, and why

assay-mcp-server 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 9d 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.
