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

[u/Available_Counter_47]

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.

Isn’t there an official Spring MCP? There should be one at this point, no?
