Why meta_list_instagram_accounts needs a policy

This tool queries and returns account information without modifying, deleting, or executing any operations. While it retrieves account data that could inform subsequent actions, the operation itself is read-only and has no blast radius if used by an AI agent beyond exposing linked accounts to the agent.

From the tool's definition Tool name contains 'list' and description states 'Lists all Instagram professional accounts linked to the user' — a retrieval operation with no side effects.

POLICY

How to control meta_list_instagram_accounts

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

policy.json

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

meta_list_instagram_accounts 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 Meta MCP Server — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
