Read live pricing, estimate planned calls, inspect one saved run or request, and use admin-only usage reports when an admin key is configured.
AI agents call fal_cost to retrieve information from Simple Fal without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool only retrieves and displays pricing, cost estimates, and usage reports. It does not modify data, execute operations, or move money. All described actions are read/query operations with no side effects.

Attacks that exploit this kind of access
Read live pricing, estimate planned calls, inspect one saved run or request, and use admin-only usage reports when an admin key is configured. It is categorised as a Read tool in the Simple Fal MCP Server, which means it retrieves data without modifying state.
Register the Simple Fal MCP server in PolicyLayer and add a rule for fal_cost: 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 Simple Fal. Nothing to install.
fal_cost 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 fal_cost 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 fal_cost. 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.
fal_cost is provided by the Simple Fal MCP server (pintar-team/simple-fal-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
