mcp-agent-langchainjs vs theodosia

Q: Which is better, mcp-agent-langchainjs or theodosia?

By GitHub stars, mcp-agent-langchainjs has more community adoption, but the best choice depends on your specific use case.

mcp-agent-langchainjs: This project demonstrates building AI agents that interact with real-world APIs using the Model Context Protocol (MCP), featuring a complete burger ordering system. The agent leverages LangChain.js for LLM reasoning and tool calling, deployed on a 100% serverless Azure architecture.; theodosia: Theodosia acts as a gatekeeper for Burr applications, mounting them as a FastMCP server to manage tool calls and ensure state machine transitions are valid. It significantly improves agent reliability and traceability by enforcing graph logic and logging all interactions, including structured refusals.
