rdkit-mcp-server vs initrunner
rdkit-mcp-server: RDKit MCP Server is an open-source MCP server that enables language models to interact with RDKit through natural language, providing agent-level access to every function in RDKit 2025.3.1 without writing code. It includes a CLI client and supports any MCP-compliant LLM.; initrunner: InitRunner lets you define an agent in one YAML file, chat with it, run it autonomously, and deploy it as a daemon triggered by cron, file changes, webhooks, or Telegram messages. It supports multiple execution modes, built-in memory, cost controls, multi-agent orchestration, and security features. Built on PydanticAI.
