Module mcp_tools 

MCP tool implementations for CodeGraph query and update operations.

Provides 4 CRUD-style tools that agents use instead of file reads/writes:

• codegraph_query_objects — filter by kind, name, parent, metrics, semantic similarity
• codegraph_update_object — modify CodeNode fields (signature, docstring, body_hash)
• codegraph_add_edge — create a relationship between CodeNodes
• codegraph_remove_edge — logical delete of an edge

These operate directly on Arrow RecordBatches — no file materialization.

Structs

NodeUpdate

Fields that can be updated on a CodeNode.

QueryFilter

Filter criteria for querying code objects.

QueryResult

Result of a query — matching CodeNodes extracted from RecordBatches.

Enums

McpToolError

Errors from MCP tool operations.

Functions

codegraph_add_edge

Add a new edge to the edges batch. Returns a new batch with the edge appended.

codegraph_query_objects

Query code objects from the nodes batch with optional filters.

codegraph_remove_edge

Remove an edge (by setting weight to -1 as a tombstone marker).

codegraph_update_object

Update a CodeNode’s fields in-place. Returns the updated batch.
