WHAT IT DOES

What test_mcp_server does on Portkey Admin

AI agents invoke test_mcp_server to trigger actions in Portkey Admin. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started.

RISK

Why test_mcp_server is rated High

This tool executes a live network connectivity check against an external MCP server. It triggers an outbound HTTP request and returns status/response time. While read-like in intent (diagnosing reachability), it actively executes an external operation whose effects depend on the target argument, fitting Execute.

From the tool's definition 'Test connectivity to an MCP server. Sends a live check' — actively sends a network request to an external MCP server

RECOMMENDED RULE

The rule that runs test_mcp_server safely

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

test_mcp_server Rate-limited

test_mcp_server stays usable, but rate-capped: a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.

}

FAQ

Questions about test_mcp_server

What does the test_mcp_server tool do? +

Test connectivity to an MCP server. Sends a live check and returns success, response time, HTTP status, and any error; use this before changing configuration or when diagnosing reachability. It is categorised as a Execute tool in the Portkey Admin MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on test_mcp_server? +

Register the Portkey Admin MCP server in PolicyLayer and add a rule for test_mcp_server: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Portkey Admin. Nothing to install.

What risk level is test_mcp_server? +

test_mcp_server is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.

Can I rate-limit test_mcp_server? +

Yes. Add a rate_limit block to the test_mcp_server rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.

How do I block test_mcp_server completely? +

Set action: deny in the PolicyLayer policy for test_mcp_server. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.

What MCP server provides test_mcp_server? +

test_mcp_server is provided by the Portkey Admin MCP server (codeswhat/portkey-admin-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
