RevClamp MCP Server & CLI (revclamp-mcp)

revclamp-mcp is the official Model Context Protocol (MCP) stdio bridge and CLI diagnostic client for **RevClamp Enterprise**. It connects Claude Desktop, Cursor, Windsurf, Cline, and CI pipelines to RevClamp's Streamable HTTP MCP endpoint (POST https://api.revclamp.com/api/mcp) with zero external npm dependencies.

Quick Start (Claude Desktop / Cursor / Windsurf)

Add revclamp-mcp to your claude_desktop_config.json or .cursor/mcp.json. Omit REVCLAMP_API_KEY to run in Stateless Sandbox Mode (zero database writes), or pass your rg_live_... workspace key from https://revclamp.com/dashboard:

{
  "mcpServers": {
    "revclamp": {
      "command": "npx",
      "args": ["-y", "github:revclamp/revclamp-mcp"],
      "env": {
        "REVCLAMP_API_KEY": "rg_live_YOUR_WORKSPACE_KEY"
      }
    }
  }
}

Or connect directly via Streamable HTTP (JSON-RPC 2.0) without installing a local binary:

curl -sS -X POST https://api.revclamp.com/api/mcp \
  -H "Content-Type: application/json" \
  -d '{"jsonrpc":"2.0","id":1,"method":"tools/list","params":{}}'

Security & Resource Bounds

  • Strict Origin Pinning: Only connects to https://api.revclamp.com/api/mcp or https://revclamp.com/api/mcp over TLS (redirect: "error"). Rejects non-HTTPS protocols, embedded credentials, and untrusted origins.
  • Bounded Execution: Enforces a hard 10,000ms request timeout (AbortSignal.timeout) and a 32,768-byte request/response payload cap.
  • Full LLM Reference: https://revclamp.com/llms-full.txt
