Tool Filtering
Selecting a small, relevant subset of tools for an agent instead of loading every available tool definition into context.
Plain English
The agent gets the few tools likely to matter, not a giant menu that slows it down and confuses it.
Example
An MCP gateway exposes only payment-log and incident-search tools for a support query, while hiding unrelated admin tools.
Why it matters
Large tool catalogs can hurt accuracy, latency, cost, and safety; filtering makes MCP-style integration practical at scale.
