## Facts

- Tool: `revoke_session`
- 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: Destructive (Critical risk)
- Registry record: grade F, identity unverified
- Server rate-limited: no
- Parameters: 0
- Recommended policy verdict: Hidden

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

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

## Why revoke_session is rated Critical

Revoking a session forcibly terminates an active user session and invalidates credentials/tokens in a way that cannot be undone (the session is destroyed). This is effectively irreversible — the original session state cannot be restored. If misused by an AI agent, it could log out users or disrupt active sessions at scale, making the blast radius high.

From the tool's own definition: "'Revoke a user session' — revoking a session is an irreversible termination action that immediately invalidates the session token"

## Use case

AI agents call revoke_session to permanently remove resources in Claude MCP Server Ecosystem, typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.

## Recommended policy (PolicyLayer)

Verdict: **Hidden**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Claude MCP Server Ecosystem:

```json
{
  "version": "1",
  "default": "deny",
  "hide": [
    "revoke_session"
  ]
}
```

## 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`
