List your generated posts with optional filtering by identity
AI agents call list_posts to retrieve information from PostIdentity 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 or lists previously generated posts, which is a read-only operation with no side effects. The optional filtering parameter does not introduce write or execute capabilities—it only constrains the data returned. There is no risk of data deletion, financial impact, or code execution.
From the tool's definition Tool name 'list_posts' and description 'List your generated posts with optional filtering by identity' indicate a query/retrieval operation with no data modification or external execution.
Attacks that exploit this kind of access
List your generated posts with optional filtering by identity. It is categorised as a Read tool in the PostIdentity MCP Server MCP Server, which means it retrieves data without modifying state.
Register the PostIdentity MCP Server MCP server in PolicyLayer and add a rule for list_posts: 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 PostIdentity MCP Server. Nothing to install.
list_posts 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 list_posts 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 list_posts. 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.
list_posts is provided by the PostIdentity MCP Server MCP server (postidentity/mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
