Capabilities

What this server is able to do. For an MCP server this is often the job itself — a terminal server runs commands because that is what it is for. Listed so you know what you are plugging in, not as an accusation.

Is this your server and something here is wrong? Tell us — corrections are free and do not require a plan.

This code can reach further than it looks

We found places where it runs commands, builds paths or queries from values it is given. None of that is a flaw by itself — it becomes one when the code changes, and code changes quietly between releases. We re-read it on every one.

Available tools 4

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

explain
explain_symptom
Map a natural-language symptom (e.g. 'my app is slow', 'hardcoded password', 'infinite react loop') to the relevant Code Auditor rule(s) and their fixes. Call this when a user describes a problem rather than naming a rule.
install
get_install_commands
Return the exact install commands for Code Auditor for a given AI agent. Call this when a user asks how to install Code Auditor, or asks for the command for a specific agent (claude, cursor, codex, gemini, agents, zcode, or all).
lookup
lookup_rule
Return the rule kind, description, default severity, detection method, and threshold for a given Code Auditor rule or analyzer. Call this when a user asks what a specific rule does (e.g. import-ban, sql-injection, n+1).
request
request_rule
Request a new Code Auditor rule. Call lookup_rule or explain_symptom first to confirm no existing rule covers it. Provide a minimal example that should be flagged and a corrected example that should not. Reduce both to the smallest code that shows the difference, and remove secrets and proprietary identifiers. Returns a receipt id.

Code Auditor MCP — questions

Answers built from our own checks of this server.

What can Code Auditor MCP do?
It exposes 4 tools, read directly from the server on our last check. Among them: explain_symptom, get_install_commands, lookup_rule, request_rule. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →
Is Code Auditor MCP working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 1 of 92 checks got a reply (1.1%), average response time 1354 ms. The bar chart above shows every period we have measured.
The registry lists Code Auditor MCP as active — why does it not respond?
The official MCP registry stores what the author submitted; it does not verify that the server still runs. We check the endpoint ourselves, and this one does not answer. Catalogues that copy the registry without checking will show it as working.
How do I connect Code Auditor MCP?
Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.
Does Code Auditor MCP need an API key?
No. Code Auditor MCP completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 4 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is Code Auditor MCP?
It answers our handshake in 1354 ms on average, which is faster than 1% of all working MCP servers we measure. That is on the slow side — worth knowing if the tool sits inside an interactive loop. The comparison comes from our own checks across the whole registry, every 15 minutes.
How many people use Code Auditor MCP?
The npm package code-auditor-mcp was installed 622 times in the last week. Week over week that is -53%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.
Is Code Auditor MCP open source?
The code is open source: it is published under the MIT licence, written in TypeScript, 8 stars on GitHub and 1 open issue. The licence covers the code in the repository, not the hosted service at codeauditormcp.com, which runs on its operator's own terms.
