Part of the Mockserver server.

mockserver_verify is read-only, but an agent in a loop can still rack up calls and cost. PolicyLayer caps every call before it runs. Live in minutes.

AI agents call mockserver_verify to retrieve information from Mockserver without modifying any data. This is common in research, monitoring, and reporting workflows where the agent needs context before taking action. Because read operations don't change state, they are generally safe to allow without restrictions -- but you may still want rate limits to control API costs.

Even though mockserver_verify only reads data, uncontrolled read access can leak sensitive information or rack up API costs. An agent caught in a retry loop could make thousands of calls per minute. A rate limit gives you a safety net without blocking legitimate use.

Read-only tools are safe to allow by default. No rate limit needed unless you want to control costs.

Every attack above starts with a tool call. PolicyLayer checks each one against your policy first, so mockserver_verify only ever does what you allow.

What does the mockserver_verify tool do? +

Verify that requests matching criteria were received by MockServer. Returns verification result with match count.. It is categorised as a Read tool in the Mockserver MCP Server, which means it retrieves data without modifying state.

How do I enforce a policy on mockserver_verify? +

Register the Mockserver MCP server in PolicyLayer and add a rule for mockserver_verify: 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 Mockserver. Nothing to install.

What risk level is mockserver_verify? +

mockserver_verify is a Read tool with low risk. Read-only tools are generally safe to allow by default.

Can I rate-limit mockserver_verify? +

Yes. Add a rate_limit block to the mockserver_verify 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 mockserver_verify completely? +

Set action: deny in the PolicyLayer policy for mockserver_verify. 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 mockserver_verify? +

mockserver_verify is provided by the Mockserver MCP server (mockserver-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
