Is this your server? Own a server? ToolFit hosted watch re-checks it every 24 h ($0.25 per 30 days) or 6 h ($0.60) and sends you an HMAC-signed webhook when its tools or grade change: POST https://api.youraitools.co/toolfit/v1/watch. To opt out, see About & opt-out.

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. params: docs, file_path, output_format, page, page_size, project*, symbol_name* |
xmp4_callers | Find direct callers of a symbol in a project. Navigate step-by-step by calling xmp4_callers again on interesting results. params: docs, file_path, output_format, page, page_size, project*, symbol_name* |
xmp4_deps | List external dependencies of a project. params: output_format, page, page_size, 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 keys). params: case_sensitive, file_glob, file_path, max_results, page, page_size, pattern*, project* |
xmp4_guide | Usage guide for xmp4 tools — read this first to learn the correct workflow params: none |
xmp4_hierarchy | Get type hierarchy (base, interfaces, derived) for a symbol in a project. params: docs, file_path, output_format, page, page_size, project*, symbol_name* |
xmp4_info | Get detailed information about a symbol in a project. params: docs, file_path, output_format, page, page_size, project*, symbol_name* |
xmp4_outline | Get outline (all symbols) for a file in a project. params: file_path*, output_format, page, page_size, 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. params: language, page, page_size, query, repo |
xmp4_search | Search symbols in a project. Use xmp4_projects first to find the project identifier. params: kind, max_results, output_format, page, page_size, project*, query* |
xmp4_server | Get server information, version, and capabilities params: none |
xmp4_source | Extract source code for a symbol in a project. params: docs, file_path, output_format, page, page_size, project*, symbol_name* |
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. params: column, file_path*, line, project* |
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.). params: docs, file_path, output_format, page, page_size, project*, symbol_name* |
xmp4_usages | Find all usages/references of a symbol in a project. params: docs, file_path, output_format, page, page_size, project*, symbol_name* |
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. params: file_path*, from_line, project*, to_line |
Entries describe changes in tool definitions. They are not statements about a server, its quality or its author. The grade measures how the tool definitions fit model providers (token cost, schema compatibility, confusable names) as scored by the ToolFit engine at the time of the listing. JSON: append .json.
