AI agents call get_post_missing to retrieve information from Posterly without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries the state of a post to validate completeness before publishing. It performs inspection and diagnosis only, with no side effects, data modification, or irreversible actions. It is purely informational, making it a Read category risk.
From the tool's definition Tool description states 'Inspect whether a post is missing required content' — the verb 'inspect' and 'use this to repair' indicate read-only validation/querying of post state. No creation, modification, deletion, or execution of external operations occurs.
Attacks that exploit this kind of access
Inspect whether a post is missing required content, media, account, platform settings, or metadata before it can publish. Use this to repair failed or imported posts. It is categorised as a Read tool in the Posterly MCP Server, which means it retrieves data without modifying state.
Register the Posterly MCP server in PolicyLayer and add a rule for get_post_missing: 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 Posterly. Nothing to install.
get_post_missing 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_post_missing 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_post_missing. 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_post_missing is provided by the Posterly MCP server (posterly-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
