AI agents call get_subject_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 retrieves reference master data (subject labels and IDs) from the Manalink platform. It is a read-only query operation with no side effects, data modification, or irreversible actions. The minimal blast radius from misuse is that an AI agent could access subject metadata, which is non-sensitive lookup information. Classification as Read with low severity is appropriate.
From the tool's definition Tool description indicates "科目マスタを取得します" (retrieves subject master data) and "get[s] the correspondence of subject labels and IDs." The verb is 'get/retrieve' with no modification, deletion, or execution capability mentioned.

Register the Manalink MCP Server MCP server in PolicyLayer and add a rule for get_subject_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_subject_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_subject_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_subject_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_subject_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.
