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

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

## Why cross_repo_traverse is rated Low

The tool appears designed to traverse repository structures to retrieve or query information across repositories. While the description is empty, the naming convention ('traverse'), the server's stated purpose of providing persistent memory and context, and the presence of sibling read-focused tools (search, graph, context retrieval) all indicate this is a Read operation with no side effects.

From the tool's own definition: "Tool name 'cross_repo_traverse' suggests navigation/traversal of repository data. Sibling tools like 'cross_repo_search', 'dependency_graph', and 'context_pack' indicate this server provides query and retrieval functions."

## Use case

AI agents call cross_repo_traverse to retrieve information from CogniRepo 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 CogniRepo:

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