Verified Safeby Amama-Fatima
Overview
Facilitates sequential, step-by-step reasoning for complex problem-solving by an AI agent, supporting thought revisions, branching, and session management.
Installation
npm install && cd server && npm install && npm startEnvironment Variables
- MCP_TOOL_TIMEOUT
- SESSION_IDLE_TIMEOUT
- SESSION_MAX_LIFETIME
- PORT
Security Notes
The server uses `child_process.spawn` to run the main MCP tool, which is safer than `exec` as it explicitly executes a local Node.js script (`build/index.js`) rather than a shell command. Input validation for tool parameters is handled by Zod schemas, mitigating common injection risks. CORS is set to `origin: "*"`, which is highly permissive; while common for LLM tool servers, it could be a concern in some deployments if not properly secured at the network level. No hardcoded secrets or 'eval' statements were found. Session management includes cleanup for idle and max lifetime sessions, preventing resource leaks.
