Get information about the current access token
AI agents call get_token_info to retrieve information from Meta Marketing API MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves information about the access token (likely expiration, scope, permissions, account associations) but does not modify, execute operations, or access sensitive user/campaign data directly. While token information could theoretically be sensitive, the act of reading token metadata is a benign Read operation.
From the tool's definition Tool name 'get_token_info' and description 'Get information about the current access token' indicate a query operation that retrieves metadata about an authentication token without modification or side effects.
Attacks that exploit this kind of access
Get information about the current access token. It is categorised as a Read tool in the Meta Marketing API MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Meta Marketing API MCP Server MCP server in PolicyLayer and add a rule for get_token_info: 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 Meta Marketing API MCP Server. Nothing to install.
get_token_info 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_token_info 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_token_info. 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_token_info is provided by the Meta Marketing API MCP Server MCP server (pythonando/meta-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
