AI Agent Hubs: Per-Agent Tool Scoping Fixes Unintended Actions

By PulseAugur Editorial · [1 sources] ·

A common issue with AI agent hubs is that they expose all available tools to every agent, leading to unintended actions. For instance, a support bot mistakenly used user management tools. The solution involves implementing per-agent tool lists, where each agent receives a filtered catalog based on its API key and role, rather than a global manifest. This approach, combined with rate-limiting on mutating operations and deriving tool visibility from OpenAPI documents, significantly reduces the risk of agents performing unauthorized actions. AI

    Your MCP Hub Exposes Every Tool to Every Agent. That's the Bug.

    <p>We stood up an internal MCP hub last quarter. It aggregated four services behind one endpoint, listed every tool in a single catalog, and let any connected agent pick what it needed. Within a week, a support bot scoped to read tickets had called <code>create_user</code> twice …
