WHAT IT DOES

What get_api_contract does on Trace

AI agents call get_api_contract to retrieve information from Trace without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why get_api_contract is rated Low

This tool retrieves and parses API contract files (OpenAPI/gRPC/GraphQL specifications) to inspect their contents. It performs read-only operations on spec files without creating, modifying, deleting, or executing code. The blast radius of misuse is minimal—an agent could gather API metadata but cannot trigger external calls, modify services, or cause destructive changes.

From the tool's definition Tool name 'get_api_contract' and description 'Get API contract... Parses spec files found in the service repo. Use to inspect a service' indicate retrieval and inspection of existing API specifications with no modification or execution.

RECOMMENDED RULE

The rule that runs get_api_contract safely

get_api_contract Allowed

get_api_contract is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

ALLOW ONLY THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect Trace, apply this rule, and every get_api_contract call is checked against it from then on.
