Decrypt data using a cryptographic key

Agent View of the PolicyLayer registry record for `decrypt_data`. HTML page: https://policylayer.com/tools/coder-rl-claude-mcpserver-dev1/decrypt-data

## Facts

- Tool: `decrypt_data`
- Server: Claude MCP Server Ecosystem (`coder-rl/claude_mcpserver_dev1`) — https://policylayer.com/tools/coder-rl-claude-mcpserver-dev1.md
- Homepage: https://github.com/Coder-RL/Claude_MCPServer_Dev1
- Risk category: Read (Low risk)
- Registry record: grade F, identity unverified
- Server rate-limited: no
- Parameters: 0
- Recommended policy verdict: Allowed

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

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

## Why decrypt_data is rated Low

Decryption is a read operation—it retrieves data in plaintext form without creating, modifying, or destroying anything. However, severity is high because decryption with an available key exposes sensitive encrypted data, and misuse by an AI agent could leak confidential information if the agent has access to cryptographic material and encrypted datasets.

From the tool's own definition: "Tool name 'decrypt_data' and description 'Decrypt data using a cryptographic key' indicates retrieval of plaintext from encrypted data without modification."

## Use case

AI agents call decrypt_data 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": {
    "decrypt_data": {}
  }
}
```

## For agents

This record is a snapshot. Live verdicts and the full registry:

- Check every server in your MCP config at once: `npx -y policylayer stack`
- Vet a server before you add it: install the mcp-precheck skill — `npx skills add https://policylayer.com` (skill text: https://policylayer.com/skill.md)
- Query the registry over MCP: endpoint `https://api.policylayer.com/mcp` — tools `check_mcp_server`, `check_mcp_stack`, `check_tool`, `search_registry`, `get_change_events`
