## Tools (as reported by the server, not verified)

- `xmp4\_callees`: Find direct callees \(methods called by\) a symbol in a project. Navigate step-by-step by calling xmp4\_callees again on interesting results.
- `xmp4\_callers`: Find direct callers of a symbol in a project. Navigate step-by-step by calling xmp4\_callers again on interesting results.
- `xmp4\_deps`: List external dependencies of a project.
- `xmp4\_grep`: Server-side regex text search over indexed project source files. Free tier: requires file\_path \(single file\). Premium tier \(XMP4\_PREMIUM\_GREP\_WALK=true\): allows file\_glob multi-file walk. Prefer xmp4\_tests\_for/xmp4\_usages for SCIP symbols — grep is for text not indexed \(comments, literals, config ke
- `xmp4\_guide`: Usage guide for xmp4 tools — read this first to learn the correct workflow
- `xmp4\_hierarchy`: Get type hierarchy \(base, interfaces, derived\) for a symbol in a project.
- `xmp4\_info`: Get detailed information about a symbol in a project.
- `xmp4\_outline`: Get outline \(all symbols\) for a file in a project.
- `xmp4\_projects`: Search and browse projects by language and name. Use this first to discover projects, then use other tools with the repo name.
- `xmp4\_search`: Search symbols in a project. Use xmp4\_projects first to find the project identifier.
- `xmp4\_server`: Get server information, version, and capabilities
- `xmp4\_source`: Extract source code for a symbol in a project.
- `xmp4\_symbol\_at`: LSP-style position→symbol lookup. Given \(file\_path, line, column\) returns the symbol whose occurrence covers that cursor position. line is 1-based; column is 0-based. Use after xmp4\_outline/xmp4\_view when you know coordinates and want the canonical symbol.
- `xmp4\_tests\_for`: Find direct tests that exercise a given symbol \(direct callers filtered to test-file candidates per language pattern: CSharp/Java/PHP: \*Test\(s\).\<ext\>; Python: test\_\*.py / \*\_test.py; TypeScript/JavaScript: \*.spec/test.\{ts,js\}; Rust: \*\_tests.rs / tests/; etc.\).
- `xmp4\_usages`: Find all usages/references of a symbol in a project.
- `xmp4\_view`: Read a raw file excerpt from an indexed project by line range. Use after xmp4\_search/xmp4\_outline locates the region of interest, or to expand a truncated xmp4\_source snippet. Hard cap of 500 lines per call.
