Get a specific memo by its ID.
AI agents call get_memo to retrieve information from Memos 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 an individual memo from the knowledge management system. Getting or fetching data by ID is a read-only operation that does not modify state, execute code, or trigger external effects. The low severity reflects minimal blast radius if misused — an agent could read memos it shouldn't, but cannot alter or delete them.
From the tool's definition Tool description states 'Get a specific memo by its ID' — a retrieval operation with no data modification or side effects.
Attacks that exploit this kind of access
Get a specific memo by its ID. It is categorised as a Read tool in the Memos MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Memos MCP Server MCP server in PolicyLayer and add a rule for get_memo: 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 Memos MCP Server. Nothing to install.
get_memo 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_memo 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_memo. 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_memo is provided by the Memos MCP Server MCP server (shaorou459/memos-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
