Get the OpenAPI schema for a specific model.
AI agents call schema to retrieve information from Fal Ai 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 and returns schema information—a read-only operation that queries model metadata. It has no side effects, does not execute code, does not modify data, and does not trigger external operations. The lowest blast radius applies: an agent misusing this tool could only retrieve unintended schema information, which poses minimal security risk.
From the tool's definition Tool name 'schema' with description 'Get the OpenAPI schema for a specific model' indicates retrieval of metadata/documentation about a model without modification or execution of the model itself.
Attacks that exploit this kind of access
Get the OpenAPI schema for a specific model. It is categorised as a Read tool in the Fal Ai MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Fal Ai MCP Server MCP server in PolicyLayer and add a rule for schema: 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 Fal Ai MCP Server. Nothing to install.
schema 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 schema 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 schema. 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.
schema is provided by the Fal Ai MCP Server MCP server (m1vision/fal.ai-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
