Parameters from the server's own tool schema.
This tool retrieves and displays information about a database function, including its source code if it is a PSQL function. It is purely a query/inspection operation with no side effects on the database state or external systems. It falls squarely into the Read category alongside sibling tools like describe-table, describe-procedure, and describe-trigger.
From the tool's definition Tool name 'describe-function' and description 'Obtiene información detallada sobre una función específica incluyendo su código fuente (si es PSQL function)' indicate retrieval of metadata and source code about a function.
Attacks that exploit this kind of access
Obtiene información detallada sobre una función específica incluyendo su código fuente (si es PSQL function). It is categorised as a Read tool in the Mcp Firebird MCP Server, which means it retrieves data without modifying state.
describe-function accepts 1 parameter: functionName. Required: functionName. The full parameter table on this page comes from the server's own tool schema.
Register the Mcp Firebird MCP server in PolicyLayer and add a rule for describe-function: 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 Mcp Firebird. Nothing to install.
describe-function 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 describe-function 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 describe-function. 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.
describe-function is provided by the Mcp Firebird MCP server (mcp-firebird). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
