# authenticate

Authenticate a user

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

## Facts

- Tool: `authenticate`
- 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: Execute (High risk)
- Registry record: grade F, identity unverified
- Server rate-limited: no
- Parameters: 0
- Recommended policy verdict: Rate-limited

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

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

## Why authenticate is rated High

Authentication is an external operation that validates credentials, creates sessions/tokens, and potentially grants access. It spans Execute territory as it triggers a security-sensitive operation with side effects (session creation, access grants). Misuse could allow unauthorized access or session manipulation.

From the tool's own definition: "'Authenticate a user' - triggers an authentication operation/flow"

## Use case

AI agents invoke authenticate to trigger actions in Claude MCP Server Ecosystem. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started.

## Recommended policy (PolicyLayer)

Verdict: **Rate-limited**. 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": {
    "authenticate": {
      "limits": [
        {
          "counter": "authenticate_rate",
          "window": "minute",
          "max": 10,
          "scope": "grant"
        }
      ]
    }
  }
}
```

## 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`
