Send a question to the Mastra server and get a response
AI agents call askMastra to retrieve information from MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool sends a question and receives a response, which is a read-only interaction with no side effects. No data is created, modified, deleted, or financial operations are performed. While the exact capabilities depend on what the Mastra server can answer, the tool itself is classified as a basic query mechanism.
From the tool's definition Tool name is 'askMastra' and description states 'Send a question to the Mastra server and get a response' — this is a query/retrieval operation that fetches information without modifying data.

Register the MCP Server MCP server in PolicyLayer and add a rule for askMastra: 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 MCP Server. Nothing to install.
askMastra is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the askMastra 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.
Set action: deny in the PolicyLayer policy for askMastra. 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.
askMastra is provided by the MCP Server MCP server (jeongjaesoon/sample-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
