WHAT IT DOES

What search_members does on UK Parliament MCP Server

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

RISK

Why search_members is rated Low

The tool appears to search or query parliamentary member data, which is a read-only operation that retrieves information without side effects. The UK Parliament MCP server is explicitly described as providing query access to public parliamentary data. No modification, execution, deletion, or financial operations are implied.

From the tool's definition Tool name 'search_members' combined with server context indicating it queries MPs and Lords data from UK Parliament. The empty description is uninformative, but the name and sibling tools (check_mp_vote, edms_for_member_id) indicate data retrieval operations.

RECOMMENDED RULE

The rule that runs search_members safely

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

search_members Allowed

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

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

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

The button opens the PolicyLayer dashboard: create your workspace, connect UK Parliament MCP Server, apply this rule, and every search_members call is checked against it from then on.
