WHAT IT DOES

What start_indexing_background does on Codebase MCP Server

AI agents invoke start_indexing_background to trigger actions in Codebase MCP Server. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.

WHY IT NEEDS A POLICY

Why start_indexing_background needs a policy

Without explicit documentation, the name 'start_indexing_background' most plausibly indicates triggering an asynchronous indexing process that scans code repositories, integrates with git, and populates a PostgreSQL database. This is an Execute action because it runs external operations (code scanning, git commands, database writes) whose side effects are substantial and depend on repository context.

From the tool's definition Tool name is 'start_indexing_background' and description is empty; however, sibling tools indicate this server manages repository indexing with git integration and pgvector embeddings.
