Get detailed information about a specific media file on PostEverywhere, including its type, dimensions, file size, upload status, and aspect ratio. Use this to check if an uploaded media file has finished processing before attaching it to a post.
AI agents call get_media to retrieve information from Posteverywhere without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and queries metadata about existing media files without modifying, deleting, or executing any operations. It is purely informational in nature—checking media properties like type, dimensions, file size, and upload status. Even though it exists within a social media posting server, its isolated functionality is a read-only query operation.
From the tool's definition Tool description states it 'Get[s] detailed information about a specific media file' and is used to 'check if an uploaded media file has finished processing'.

Get detailed information about a specific media file on PostEverywhere, including its type, dimensions, file size, upload status, and aspect ratio. Use this to check if an uploaded media file has finished processing before attaching it to a post. It is categorised as a Read tool in the Posteverywhere MCP Server, which means it retrieves data without modifying state.
Register the Posteverywhere MCP server in PolicyLayer and add a rule for get_media: 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 Posteverywhere. Nothing to install.
get_media 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_media 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_media. 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_media is provided by the Posteverywhere MCP server (posteverywhere/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
