THE RISK

Low Risk

Why get_bluesky_posts needs a policy

This tool fetches publicly available social media data about the user. It performs read-only access to Bluesky posts associated with the configured handle. There is no data modification, deletion, code execution, or financial impact. The severity is low because Bluesky posts are typically public by default, and retrieving them poses minimal risk even if misused by an AI agent.

From the tool's definition Tool retrieves 'recent posts' from a Bluesky account — a query operation with no side effects. The description uses 'Get', a typical Read operation verb.

POLICY

How to control get_bluesky_posts

PolicyLayer is an MCP gateway — it sits between your AI agents and Mcp Me, and nothing reaches the server without passing your rules. This is the rule we recommend for get_bluesky_posts:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "get_bluesky_posts": {}
  }
}

get_bluesky_posts is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Create a free account and register Mcp Me — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
