特定のメンバーを取得
AI agents call get_member to retrieve information from Ghost MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and retrieves data about a specific member from the Ghost CMS without modifying, deleting, or executing any operations. It is a read-only operation consistent with other 'get_*' tools on this server (get_authors, get_members, get_page, get_page_by_slug). The blast radius of misuse is minimal—an attacker could only access member information already stored in the system.
From the tool's definition Tool name 'get_member' and description 'Get a specific member' (translated from Japanese '特定のメンバーを取得') indicate a retrieval operation with no side effects.
Attacks that exploit this kind of access
特定のメンバーを取得. It is categorised as a Read tool in the Ghost MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Ghost MCP Server MCP server in PolicyLayer and add a rule for get_member: 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 Ghost MCP Server. Nothing to install.
get_member 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_member 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_member. 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_member is provided by the Ghost MCP Server MCP server (mtane0412/ghost-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
