Return Threads posts in which the authenticated user is mentioned.
AI agents call get_mentions to retrieve information from Threads 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 existing data about mentions of the authenticated user. It has no side effects—it does not create, modify, delete, or execute any operations. The scope is limited to reading the user's own mention data, which is a standard Read operation typical of social media APIs.
From the tool's definition Tool name is 'get_mentions' and description states it returns (retrieves) Threads posts in which the authenticated user is mentioned. Uses the verb 'Return', indicating data retrieval with no modification or deletion.
Attacks that exploit this kind of access
Return Threads posts in which the authenticated user is mentioned. It is categorised as a Read tool in the Threads MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Threads MCP Server MCP server in PolicyLayer and add a rule for get_mentions: 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 Threads MCP Server. Nothing to install.
get_mentions 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_mentions 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_mentions. 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_mentions is provided by the Threads MCP Server MCP server (poisonstefani-dev/threads-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
get_mentions is one line of Threads MCP Server's registry record.
The record carries the whole server: verified identity, auth posture, risk grade, every tool classified, recommended policy — re-checked continuously.
