Hybrid semantic + keyword search over the connected repository's actual indexed content. Use this for open-ended questions ("where is rate limiting implemented?", "how are uploads validated?") where you don't already know an exact symbol or file name -- for those, use get_symbol_definition or get_dependencies instead, they're more precise.

Finds where a function, class, or method is actually defined in this repo -- exact file, line range, and signature-relevant metadata (async, decorators, docstring if present). Use this before assuming a symbol's location/signature from memory or from a similarly-named symbol in a different file.

{
  "type": "object",
  "properties": {
    "name": {
      "type": "string",
      "description": "The bare symbol name (e.g. \"get_upstream_impact\"), or\n\"ClassName.method_name\" for a specific method when the bare\nname is ambiguous across multiple classes."
    }
  },
  "required": [
    "name"
  ],
  "additionalProperties": false
}

{
  "type": "object",
  "properties": {
    "result": {
      "type": "string"
    }
  },
  "required": [
    "result"
  ],
  "x-fastmcp-wrap-result": true
}

Every place in this repo that calls the given function or method -- a COMPLETE list from the parsed call graph, not a best-effort guess. Use this before renaming/changing a function's signature, or when you need to understand a function's blast radius before modifying it.

{
  "type": "object",
  "properties": {
    "function_name": {
      "type": "string",
      "description": "The bare function/method name (e.g. \"save_user\").\nIf multiple unrelated symbols share this name, results are\ngrouped by which definition they call."
    }
  },
  "required": [
    "function_name"
  ],
  "additionalProperties": false
}

{
  "type": "object",
  "properties": {
    "result": {
      "type": "string"
    }
  },
  "required": [
    "result"
  ],
  "x-fastmcp-wrap-result": true
}

Every function/method the given function calls -- what it depends on to do its job. Use this to understand a function's behavior by seeing what it delegates to, before assuming what it does from its name alone.

{
  "type": "object",
  "properties": {
    "function_name": {
      "type": "string",
      "description": "The bare function/method name (e.g. \"sync_repository\")."
    }
  },
  "required": [
    "function_name"
  ],
  "additionalProperties": false
}

{
  "type": "object",
  "properties": {
    "result": {
      "type": "string"
    }
  },
  "required": [
    "result"
  ],
  "x-fastmcp-wrap-result": true
}

What a specific file imports/depends on. Use this to understand a file's place in the codebase before assuming what's available to it, or before moving/refactoring it.

{
  "type": "object",
  "properties": {
    "file_path": {
      "type": "string",
      "description": "Repo-relative path (e.g. \"utils/knowledge_graph/graph_builder.py\").\nMatches by exact path first, then by suffix if no exact match\n(so \"graph_builder.py\" alone will still resolve if unambiguous)."
    }
  },
  "required": [
    "file_path"
  ],
  "additionalProperties": false
}

{
  "type": "object",
  "properties": {
    "result": {
