Ejentum MCP

MCP server that improves LLM reasoning on complex, multi-step, or multi-constraint tasks. Before the agent generates, it calls one of eight tools to retrieve a cognitive operation: a structured procedure (numbered steps with the failure pattern to refuse and a falsification test) paired with an executable reasoning topology (a DAG of those steps with decision gates, parallel branches, bounded loops, meta-cognitive…. Its 8 documented tools cover adaptive, reasoning, code, anti.

People connecting developer tools tools to Claude, Cursor, VS Code, or another MCP client. The project is written in JavaScript.

01 · Install Ejentum MCP

before you install - you'll need

EJENTUM_API_KEY

Environment variables documented in the project's README - it lists which are required and which have defaults.

Claude Code

claude mcp add ejentum-ejentum-mcp --transport http https://api.ejentum.com/mcp

Claude Desktop / Cursor / VS Code - add to config

{
  "mcpServers": {
    "ejentum-ejentum-mcp": {
      "url": "https://api.ejentum.com/mcp"
    }
  }
}

Same JSON for Cursor. For VS Code, rename the top-level key from `mcpServers` to `servers`.

Using another client? Same JSON, different key

Security posture

What to check before giving this server access to your agent - from the registry, GitHub, and our own probes. We don't score safety; we show what's verifiable.

runs as local process (stdio) - runs on your machine with your user's permissions · remote - your agent's requests go to api.ejentum.com

endpoint auth requires authentication - rejected our unauthenticated MCP initialize

license MIT - declared in the repository

npm package ejentum-mcp - unscoped; check the name against the project README before installing

registry namespace io.github.ejentum is GitHub-verified and matches the repo owner
