Claude Code: ask. ### `xmp4_grep` - Nothing in its name or description says what it does, so it is counted as a write. Description, as the server wrote it: ```untrusted-server-text 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). ``` ### `xmp4_guide` - Nothing in its name or description says what it does, so it is counted as a write. Description, as the server wrote it: ```untrusted-server-text Usage guide for xmp4 tools — read this first to learn the correct workflow ``` ### `xmp4_source` - Nothing in its name or description says what it does, so it is counted as a write. Description, as the server wrote it: ```untrusted-server-text Extract source code for a symbol in a project. ``` ### `xmp4_symbol_at` - Nothing in its name or description says what it does, so it is counted as a write. Description, as the server wrote it: ```untrusted-server-text 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. ``` ## Only reads (12) Looks things up and changes nothing. Claude Code: allow. ### `xmp4_callees` - The description's first verb is "find": a word for reading. Description, as the server wrote it: ```untrusted-server-text 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` - The description's first verb is "find": a word for reading. Description, as the server wrote it: ```untrusted-server-text Find direct callers of a symbol in a project. Navigate step-by-step by calling xmp4_callers again on interesting results. ``` ### `xmp4_deps` - The description's first verb is "list": a word for reading. Description, as the server wrote it: ```untrusted-server-text List external dependencies of a project. ``` ### `xmp4_hierarchy` - The description's first verb is "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text Get type hierarchy (base, interfaces, derived) for a symbol in a project. ``` ### `xmp4_info` - The description's first verb is "get": a word for reading.

Use this first to discover projects, then use other tools with the repo name. ``` ### `xmp4_search` - The name "xmp4_search" says "search": a word for reading. Description, as the server wrote it: ```untrusted-server-text Search symbols in a project. Use xmp4_projects first to find the project identifier. ``` ### `xmp4_server` - The description's first verb is "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text Get server information, version, and capabilities ``` ### `xmp4_tests_for` - The description's first verb is "find": a word for reading. Description, as the server wrote it: ```untrusted-server-text Find direct tests that exercise a given symbol (direct callers filtered to test-file candidates per language pattern: CSharp/Java/PHP: *Test(s).; Python: test_*.py / *_test.py; TypeScript/JavaScript: *.spec/test.{ts,js}; Rust: *_tests.rs / tests/; etc.). ``` ### `xmp4_usages` - The description's first verb is "find": a word for reading.

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. ``` ## Claude Code permissions For `.claude/settings.json`, assuming the server is installed as `xmp4`: ```json { "permissions": { "allow": [ "mcp__xmp4__xmp4_callees", "mcp__xmp4__xmp4_callers", "mcp__xmp4__xmp4_deps", "mcp__xmp4__xmp4_hierarchy", "mcp__xmp4__xmp4_info", "mcp__xmp4__xmp4_outline", "mcp__xmp4__xmp4_projects", "mcp__xmp4__xmp4_search", "mcp__xmp4__xmp4_server", "mcp__xmp4__xmp4_tests_for", "mcp__xmp4__xmp4_usages", "mcp__xmp4__xmp4_view" ], "ask": [ "mcp__xmp4__xmp4_grep", "mcp__xmp4__xmp4_guide", "mcp__xmp4__xmp4_source", "mcp__xmp4__xmp4_symbol_at" ], "deny": [] } } ```
