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.

Builds a database query by concatenation cortex-core/src/lib.rs:1462
                    engine.record_op(crate::sync::oplog::SyncPayload::MemoryDelete { id })
                {
                    tracing::warn!(error = %e, "failed to record privacy retraction");
    execSync(`tar xzf "${tarPath}" -C "${tmpDir}"`, { stdio: "pipe" });
  el.innerHTML = items.map(m => `

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.
