Common questions

Is Cortex MCP — Multi-Level Reasoning Server safe?

It passed 1 of 3 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed 8 months ago, and the latest version (1.11.0) reached the registry 8 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Node.js on your computer.

Cortex MCP

Multi-level reasoning MCP server with configurable depth levels, session-based state management, structured thought input, and real-time trace resources.

Overview

Cortex MCP is a stdio-only MCP server for stateful, depth-controlled reasoning. The runtime entrypoint in src/index.ts connects createServer() to StdioServerTransport, and the server surface in src/server.ts enables tools, prompts, completions, logging, and subscribable resources around a single session-based reasoning engine.

The live MCP surface confirmed by Inspector is 1 tool, 6 concrete resources, 4 resource templates, and 7 prompts. Sessions are stored in memory, exposed as MCP resources, and cleared on process restart.

Key Features

  • reasoning_think supports step-by-step sessions, run_to_completion batches, rollback, early conclusion, and structured observation / hypothesis / evaluation input.
  • Four depth levels are built into the engine: basic, normal, high, and expert, each with bounded thought ranges and token budgets.
  • Prompt helpers expose reasoning.basic, reasoning.normal, reasoning.high, reasoning.expert, reasoning.continue, reasoning.retry, and get-help.
  • Resource endpoints expose internal docs plus live session lists, per-session JSON views, full markdown traces, and individual thought documents.
  • Completions are wired for levels, session IDs, and thought names through completable() and resource-template completion hooks.

Requirements

  • Node.js >=24 for local npx or npm usage.
  • An MCP client that supports stdio transport.
  • Optional: Docker if you want to build or run the container image defined by Dockerfile.
