The portal said "Live." For a few hours the page kept saying the connector didn't exist.
This has caught other people too. A pull request to FastMCP describes the same problem: its titles were going only into the top-level field, so the Claude connectors directory saw the tools as nameless. If the portal says your tools are missing titles and you can clearly see the titles in the schema, check annotations.title before doing anything more dramatic. That string is also what users see in the confirmation dialog, so they get "Create post" instead of create_post.

Elicitation didn't die in the MCP stateless rewrite. It's the only one that survived.
pyright and ty both tolerate it and see all six. Fixed upstream in PrefectHQ/fastmcp#4774.

How an Unbounded fastmcp Version Constraint Took Down Production with 421 Misdirected Request
We run a Model Context Protocol server on Cloud Run, built with fastmcp, sitting behind a custom domain on an HTTPS load balancer. It hadn't been redeployed in three months. When we finally shipped a routine release, every single request started failing with 421 Misdirected Request. No code changes. No infra changes we were aware of. Just a version bump.

Vibecoding Our First MCP Server
The first version was deliberately simple. As I described in this post my team and I had very limited knowledge of MCP servers and add to discover the topic, and learn it while (vibe)coding the Proof of Concept. It turned out that creating an MCP server with STDIO transport is really trivial. Especially thanks to FastMCP: in the end it's about wrapping the desired endpoints of our API with the @mcp.tool() annotation.
