MCP server exposing the Ejentum reasoning harness as eight tools: four dynamic (`reasoning`, `code`, `anti-deception`, `memory`) plus four adaptive
Most developer tooling work still happens through a UI a human drives. Ejentum MCP MCP server moves it into the conversation instead. MCP server exposing the Ejentum reasoning harness as eight tools: four dynamic (reasoning, code, anti-deception, memory) plus four adaptive (adaptive-reasoning, adaptive-code, adaptive-anti-deception, adaptive-memory) that.
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 exits, and escape paths). The agent reads both layers before producing its response.
Because this one is hosted, setup is mostly authentication — you point your client at the endpoint and approve access. Nothing runs on your machine, so there is no runtime to keep patched.
The server publishes 14 tools. What each one is for:
macOS — ~/Library/Application Support/Claude/claude_desktop_config.jsonWindows — %APPDATA%\Claude\claude_desktop_config.jsonreasoning — reasoningcode — codeanti-deception — anti-deceptionmemory — memoryadaptive-reasoning — adaptive-reasoningadaptive-code — adaptive-codeadaptive-anti-deception — adaptive-anti-deceptionadaptive-memory — adaptive-memoryOrder — SlotToken — MeaningConfiguration is passed through the environment: EJENTUM_API_KEY, YOUR_EJENTUM_API_KEY, EJENTUM_API_URL. Treat anything key-shaped as a real credential — scope it to the minimum the server needs, and rotate it if it ever lands in a shared config.
Among the developer tooling options, the useful question is rarely "what can it do" but "what does it cost you to run" — permissions, credentials, and how much of your context its toolset consumes. Ejentum MCP's toolset — macOS, Windows, reasoning and 11 more — is a fair guide to whether it matches your workflow. It is maintained by ejentum; worth a glance at recent repository activity before you build anything load-bearing on it.
