Tool changes

No tool definition changes recorded. A server's first observation is its baseline; later probes record what changes.

Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed. How it is computed.

Derived from observable signals (official registry feed and our own credential-free probes); no code audit performed. How it is computed.

Tools (16)

xmp4_calleesFind direct callees (methods called by) a symbol in a project. Navigate step-by-step by calling xmp4_callees again on interesting results.
xmp4_callersFind direct callers of a symbol in a project. Navigate step-by-step by calling xmp4_callers again on interesting results.
xmp4_depsList external dependencies of a project.
xmp4_grepServer-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 keys).
xmp4_guideUsage guide for xmp4 tools — read this first to learn the correct workflow
xmp4_hierarchyGet type hierarchy (base, interfaces, derived) for a symbol in a project.
xmp4_infoGet detailed information about a symbol in a project.
xmp4_outlineGet outline (all symbols) for a file in a project.
xmp4_projectsSearch and browse projects by language and name. Use this first to discover projects, then use other tools with the repo name.
xmp4_searchSearch symbols in a project. Use xmp4_projects first to find the project identifier.
xmp4_serverGet server information, version, and capabilities
xmp4_sourceExtract source code for a symbol in a project.
xmp4_symbol_atLSP-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_forFind 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_usagesFind all usages/references of a symbol in a project.
xmp4_viewRead 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.

Schemas: list_tools.
