ejentum

v0.2.0

Ejentum MCP server. Eight tools (four dynamic: reasoning, code, anti-deception, memory; four adaptive: adaptive-reasoning, adaptive-code, adaptive-anti-deception, adaptive-memory) that retrieve task-matched cognitive operations from a library of 679. Each operation is a structured procedure paired with an executable reasoning topology DAG. Adaptive tools require Go or Super tier. Stdio via `npx -y ejentum-mcp` or hosted HTTPS at https://api.ejentum.com/mcp.

Install ejentum for Codex

Installs for the current user
codex plugin marketplace add hashgraph-online/awesome-codex-plugins
codex plugin marketplace upgrade awesome-codex-plugins
codex plugin add ejentum@awesome-codex-plugins

Paste and run these commands in a terminal with Codex. They add and refresh the awesome-codex-plugins catalog, then install this plugin.

Compatibility: the page URL and API slug “ejentum” remain stable.

  • Codex: ejentum@agent-plugin-marketplaceejentum@awesome-codex-plugins

The installer fetches third-party code from the source repository shown on this page. This directory validates manifest structure and source location, but does not perform a security audit; review the manifest, components, and source before installing.

Get the source manually
git clone https://github.com/hashgraph-online/awesome-codex-plugins

Clone the source repository, then follow its setup instructions to add the plugin to a compatible client. The plugin root is plugins/ejentum/ejentum-mcp/.

Each operation is engineered in two layers: a natural-language procedure (named failure pattern, numbered steps, suppression vectors, falsification test) and an executable reasoning topology (a DAG with decision gates, parallel branches, bounded loops, meta-cognitive exit nodes). Eight tools split into two retrieval modes: four dynamic tools (reasoning, code, anti-deception, memory) return the top-1 matched operation in its abstract form; four adaptive tools (adaptive-reasoning, adaptive-code, adaptive-anti-deception, adaptive-memory) additionally run an adapter LLM step that rewrites the procedure and DAG nodes with task-specific identifiers. Two install paths: stdio (this plugin) via `npx -y ejentum-mcp` for Codex CLI subprocess mode, or hosted HTTPS at https://api.ejentum.com/mcp for HTTP-MCP clients (Bearer auth via EJENTUM_API_KEY). 30-day free trial; adaptive tools require Go or Super tier.",
