## Install

### How to install RevClamp MCP Server in Claude Code

1. Add the server

```bash
claude mcp add --transport http revclamp-mcp https://revclamp.com/api/mcp
```

2. Verify it's connected

```bash
claude mcp list
```

3. Sharing it with your team?

   Add `--scope project` to write it to .mcp.json in the repository root, which you can commit (with the secrets left as environment variables).

4. Use it in a session

   Ask Claude to use the tools this server exposes (e.g. revclamp_audit_revenue_leakage, revclamp_evaluate_ghost_usage, revclamp_stage_stripe_dispute_ce3). It discovers them automatically.

### How to install RevClamp MCP Server in Claude Desktop

1. Open your MCP config

   macOS: ~/Library/Application Support/Claude/claude_desktop_config.json · Windows: %APPDATA%\Claude\claude_desktop_config.json

2. Add this server

```json
{
  "mcpServers": {
    "revclamp-mcp": {
      "command": "npx",
      "args": [
        "-y",
        "mcp-remote",
        "https://revclamp.com/api/mcp"
      ]
    }
  }
}
```

3. Why the wrapper?

   This is a remote (HTTP) server and Claude Desktop only launches local processes, so mcp-remote proxies the connection. It will open a browser window if the server needs OAuth.

4. Restart Claude Desktop

   The tools appear under the 🔌 menu once the app reloads.

### How to install RevClamp MCP Server in Cursor

1. Create / edit .cursor/mcp.json in your project

```json
{
  "mcpServers": {
    "revclamp-mcp": {
      "url": "https://revclamp.com/api/mcp"
    }
  }
}
```

2. Enable it

   Cursor Settings → MCP → toggle the server on. Tools become available to the Composer/Agent.

### How to install RevClamp MCP Server in Codex CLI

1. Add to ~/.codex/config.toml

```toml
[mcp_servers.revclamp-mcp]
command = "npx"
args = ["-y", "mcp-remote", "https://revclamp.com/api/mcp"]
```

2. Why the wrapper?

   Codex runs MCP servers as local processes, so mcp-remote bridges this HTTP endpoint to stdio.

3. Run Codex

   Codex loads MCP servers from config.toml on startup and exposes their tools to the agent.

### How to install RevClamp MCP Server in Windsurf

1. Edit ~/.codeium/windsurf/mcp_config.json

```json
{
  "mcpServers": {
    "revclamp-mcp": {
      "serverUrl": "https://revclamp.com/api/mcp"
    }
  }
}
```

2. Reload

   Windsurf → Cascade → refresh MCP servers. Cascade can now call the tools.

### How to install RevClamp MCP Server in Cline

1. Open Cline → MCP Servers → Configure

   Adds to cline_mcp_settings.json.

2. Add the server

```json
{
  "mcpServers": {
    "revclamp-mcp": {
      "type": "streamableHttp",
      "url": "https://revclamp.com/api/mcp"
    }
  }
}
```

### How to install RevClamp MCP Server in VS Code

1. Create .vscode/mcp.json

```json
{
  "servers": {
    "revclamp-mcp": {
      "type": "http",
      "url": "https://revclamp.com/api/mcp"
    }
  }
}
```

2. Start it

   VS Code shows a ▶ Start action above the server entry. Agent mode (Copilot Chat) can then use the tools.
