## Example call (MCP tools/call, JSON-RPC 2.0)

```json
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "get_api_contract",
    "arguments": {}
  }
}
```

## 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 own 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."

## Use case

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.

## Recommended policy (PolicyLayer)

Verdict: **Allowed**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Trace:

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "get_api_contract": {}
  }
}
```
