Open a C++ workspace and start one persistent module-aware clangd process.

Return clangd readiness, warmup progress, module counts, PCM/modmap coverage, and recent errors.

Reload compile commands and rebuilt PCM/modmap artifacts, restarting clangd without rewriting unchanged cache files.

Start non-blocking AST warmup. Poll workspace_status; other MCP tools remain available.

Search named C++ modules and partitions, including entities clangd does not expose as symbols.

Resolve a module to interface units, imports, dependencies, and importing translation units.

Use clangd AST to find non-trivial definitions in module interfaces and verify matching .cpp implementation units.

Format C++/module source with clangd. Preview is the default; apply=true explicitly writes the file and updates clangd.

Return clangd's detailed AST plus synthetic module context for module declarations/imports.

List declarations in a C++ source or module unit using clangd's hierarchical symbol view.

Search clangd symbols and named C++ modules in one request.

Find a declaration/definition across module BMIs. Position values are 1-based; needle is often easier for agents.

Find indexed references to a declaration across module units and translation units.

Parse a file and return clangd diagnostics after module resolution.
