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

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

## Why trace_data_lineage is rated Low

Data lineage tracing is fundamentally a read-only operation that queries metadata about data dependencies, sources, and transformations. It does not create, modify, delete, execute code, or transfer funds. The tool provides visibility into data relationships, which is a non-destructive analytical capability similar to a search or audit function.

From the tool's own definition: "Tool name 'trace_data_lineage' and description 'Trace data lineage upstream and downstream' indicate a query/inspection operation that retrieves and maps data flow relationships without modifying or executing operations."

## Use case

AI agents call trace_data_lineage to retrieve information from Claude MCP Server Ecosystem 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 Claude MCP Server Ecosystem:

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