## Facts

- Tool: `osint_search`
- Server: Recon (`deltafantazulu/recon`) — https://policylayer.com/tools/deltafantazulu-recon.md
- Homepage: https://github.com/deltafantazulu/recon
- Risk category: Read (Low risk)
- Registry record: grade B, identity unverified
- Server rate-limited: no
- Parameters: 2
- Recommended policy verdict: Allowed

## Parameters

| Parameter | Type | Required | Description |
| --- | --- | --- | --- |
| `limit` | number | no | Maximum number of results to return (default: 5000). Lower values = faster responses. Range: 100-9000 |
| `query` | string | no | The search query (email, phone, username, domain, etc.) |

Parameters from the server's own tool schema.

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

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

## Why osint_search is rated Low

This is fundamentally a read operation that queries leaked data repositories. While the tool accesses sensitive information (exposed email addresses, phone numbers, usernames, domains), it retrieves existing data without side effects.

From the tool's own definition: "Tool performs 'search' and 'returns results from multiple databases' with 'targeted lookups and streamlined retrieval of findings.' No modification, deletion, or execution occurs."

Risk signals: Accepts freeform code/query input (query)

## Use case

AI agents call osint_search to retrieve information from Recon 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 Recon:

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