List all ad accounts the authenticated user has access to. Returns each account's name, numeric ID, platform type, business name, currency, and data_synced status. Use the ad_account_id from the results when calling other tools.
Part of the Meta Ads MCP server. Enforce policies on this tool with Intercept, the open-source MCP proxy.
AI agents call list_ad_accounts to retrieve information from Meta Ads without modifying any data. This is common in research, monitoring, and reporting workflows where the agent needs context before taking action. Because read operations don't change state, they are generally safe to allow without restrictions -- but you may still want rate limits to control API costs.
Even though list_ad_accounts only reads data, uncontrolled read access can leak sensitive information or rack up API costs. An agent caught in a retry loop could make thousands of calls per minute. A rate limit gives you a safety net without blocking legitimate use.
Read-only tools are safe to allow by default. No rate limit needed unless you want to control costs.

List all ad accounts the authenticated user has access to. Returns each account's name, numeric ID, platform type, business name, currency, and data_synced status. Use the ad_account_id from the results when calling other tools.. It is categorised as a Read tool in the Meta Ads MCP Server, which means it retrieves data without modifying state.
Add a rule in your Intercept YAML policy under the tools section for list_ad_accounts. You can allow, deny, rate-limit, or validate arguments. Then run Intercept as a proxy in front of the Meta Ads MCP server.
list_ad_accounts 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_ad_accounts rule in your Intercept 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 Intercept policy for list_ad_accounts. 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_ad_accounts is provided by the Meta Ads MCP server (meta-ads-mcp-server). Intercept sits as a proxy in front of this server to enforce policies before tool calls reach the server.
