Tool Catalog Filtering
Tool catalog filtering is the practice of restricting the tools an agent can discover and invoke by returning a filtered tools/list response based on the agent's identity, task context, and access policy.
Why this matters for AI agents
Filtering the catalog before the agent sees it reduces prompt injection risk, limits the agent's action surface, and enforces least privilege without requiring the agent or tool server to change.
How AgntID relates
AgntID applies tool catalog filtering at the tools/list interception point, ensuring each agent receives only the tools it is authorized to use for the current task.
The static IAM gap
Standard MCP tool discovery returns the full catalog. Infrastructure teams have no native mechanism to filter tool visibility per agent or per task.

What is tool catalog filtering?
Tool catalog filtering is the practice of restricting the tools an agent can discover and invoke by returning a filtered tools/list response based on the agent's identity, task context, and access policy.
How does filtering the catalog before tool discovery reduce risk?
Filtering the catalog before the agent sees it reduces prompt injection risk, limits the agent's action surface, and enforces least privilege without requiring the agent or tool server to change.
How does AgntID implement tool catalog filtering?

Secure every agent tool call at execution time.
AgntID gives infrastructure teams scoped, ephemeral access control for AI agents without replacing IAM, MCP servers, tools, or agent frameworks.
