Description
Vessel is a local-first observability proxy for LLM traffic: capture, search, replay, and compare every prompt across Ollama, OpenAI, and Anthropic and all other backends. One binary, no account, nothing leaves your machine. It also hosts a small MCP server so your coding agents can query traces in real-time - very useful for troubleshooting

Could you build this?
Yes A local HTTP proxy that intercepts LLM API calls, logs request/response payloads to SQLite, and serves an MCP endpoint or local web dashboard is well within vibe-coding scope.
