# Semantic Code Search

> Use when searching a codebase by behavior, intent, or natural language description rather than exact identifiers. Activates the CocoIndex Code MCP server for semantic code search — finding implementations without knowing exact names, exploring unfamiliar codebases, or locating code by concept.

Use `mcp__cocoindex-code__search` for semantic code search when:

- Searching for code by meaning or description rather than exact text
- Exploring unfamiliar parts of the codebase
- Looking for implementations without knowing exact names
- Finding similar code patterns or related functionality

Prefer Grep/Glob when you know exact identifiers, filenames, or string literals. Prefer semantic search when you know what the code *does* but not what it's *called*.

The CocoIndex Code MCP server is bundled with this plugin via `.mcp.json` and launches automatically using `uvx cocoindex-code==0.1.11` — no pre-installation required. If `mcp__cocoindex-code__search` is not listed in available tools, report BLOCKED — this is a configuration error, not a fallback scenario.
