AI agents call get_grade_master to retrieve information from Manalink MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool fetches reference data (grade master mappings) from the Manalink platform. It is a read-only operation that retrieves static lookup information used to map grade level labels to IDs. There are no modifications, deletions, code execution, or financial implications. The blast radius of misuse is minimal—an attacker could only access publicly available grade level reference data.
From the tool's definition Tool name 'get_grade_master' and description indicate retrieval of grade level master data. Japanese description translates to 'Retrieves the grade master.

Register the Manalink MCP Server MCP server in PolicyLayer and add a rule for get_grade_master: 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 Manalink MCP Server. Nothing to install.
get_grade_master 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 get_grade_master 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 get_grade_master. 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.
get_grade_master is provided by the Manalink MCP Server MCP server (texmeijin/manalinkmcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
