We recently built an MCP server (https://github.com/tinybirdco/mcp-tinybird/tree/main) so our users could ask questions to their workspace. We released fast and since MCP servers run locally we lacked observability on product metrics, error monitoring and all that stuff you usually want when you are in production.
Are you finding building MCP integrations to be worth it? We've been using agents (e.g. langchain), which are pretty good at bringing in context and taking actions. Tool results become part of the context --it just works.
Good thing to me (besides being an open spec) is their simplicity, with libraries such as FastMCP you can just bring stuff you already have implemented into Claude (or any MCP client).
