WHAT IT DOES

What capability_search does on Arifos

AI agents call capability_search to retrieve information from Arifos without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why capability_search is rated Low

This tool retrieves and searches information about available MCP tools without creating, modifying, deleting, executing code, or moving funds. It is a passive read operation that discovers metadata about tools in a federated system. The low severity reflects minimal risk: even if misused, a search operation cannot directly harm data or systems.

From the tool's definition Tool description states it performs 'Semantic search over the federation's 97 MCP tools' — a query/retrieval operation with no modification or execution of external systems.

RECOMMENDED RULE

The rule that runs capability_search safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Arifos, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For capability_search, this is the rule to start with:

capability_search Allowed

capability_search is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

  "default": "deny",
  "tools": {
    "capability_search": {}
  }
}

ALLOW ONLY THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect Arifos, apply this rule, and every capability_search call is checked against it from then on.
