What it does

Sourcerer MCP connects AI agents to your local codebase via semantic search, allowing them to find conceptually relevant functions, classes, and code blocks without reading entire files. This drastically reduces token consumption and cognitive load for the model.

Tools

semantic_search: Find relevant code using semantic search.
get_chunk_code: Retrieve specific code chunks by their unique ID.
find_similar_chunks: Discover code blocks similar to a given chunk.
index_workspace: Manually trigger a re-indexing of the workspace.
get_index_status: Check the current progress of the workspace indexing.
