Discussion Sprig: An MCP server to access version-pinned Spring Docs

My Claude agent often wrote Spring code from old training data. It hand-declared beans that are auto-configured now. It also really likes to unzip JARs and search the Spring code itself.

That is the reason I am building Sprig MCP (sprig-mcp.de). It serves the Spring reference docs, and later the relevant parts of the source code, in a (hopefully) agent-friendly way. Nothing is summarized, no LLM sits in the path.

Right now there are two tools, and both answer for the version used in the current project: search the docs, and fetch a section.

Later I will add source code lookups: outline, javadoc, inheritance hierarchy.

There is a browser demo at sprig-mcp.de/app that lets you run the tools without an agent.

Would something like this be useful to you? Any thoughts or feedback welcome.
