WHAT IT DOES

What mcp_discover does on Hyperion

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

Parameter	Type	Required	Description
`limit`	number	—	Max results to return (default 10, max 50).
`query`	string	Yes	Free-text query describing the capability you need (e.g. "payments", "browser automation", "sql database", "image generation").

Parameters from the server's own tool schema.

RISK

Why mcp_discover is rated Low

Even though mcp_discover only reads data, uncontrolled read access leaks sensitive information and racks up API costs: an agent caught in a retry loop can make thousands of calls a minute without anyone noticing.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs mcp_discover safely

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

mcp_discover Allowed

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

View as policy code

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "mcp_discover": {}
  }
}

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

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