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.

Runs an external command packages/cortex-rmcp/bin/cortex.js:9

if (!fs.existsSync(binary)) { const installer = path.resolve(__dirname, "..", "scripts", "install.js"); const install = spawnSync(process.execPath, [installer], { stdio: "inherit" }); if (install.status !== 0) fail("binary is not installed; postinstall may have failed"); }

Builds a database query by concatenation src/db/error_signatures.rs:108, src/db/queries.rs:1279

         DO UPDATE SET count_in_window = count_in_window + excluded.count_in_window",

Asks for container control access src/db/graph_findings_tests.rs:52, src/heartbeat_agent.rs:25, src/agent_deploy.rs:450

                source: Some("/var/run/docker.sock".to_string()),

Touches key and credential files src/main.rs:339

            anyhow::bail!("no hosts found in ~/.ssh/config");

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.

Cortex — questions

Answers built from our own checks of this server.

Is Cortex working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 2 of 90 checks got a reply (2.2%), average response time 325 ms. The bar chart above shows every period we have measured.

The registry lists Cortex 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 Cortex?

Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.

Does Cortex need an API key?

No. Cortex completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. This is what we observed, not what the docs claim.

How fast is Cortex?

It answers our handshake in 325 ms on average, which is faster than 50% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.

Is Cortex open source?

Yes — it is published under the AGPL-3.0 licence, written in Rust, 3 stars on GitHub and 4 open issues. The source link is on this page, so you can read exactly what it does with your data before you connect it.
