## Connection methods

| Method | Best for | Setup | Why agents use it |
|---|---|---|---|
| MCP | Agent-native discovery and tool calling | One npx command | Best fit for Claude Code, Codex CLI, Cursor, Windsurf, and other MCP clients. |
| CLI | Terminal workflows and debugging | Same npm package, no restart needed | Fastest way to browse tools, inspect schemas, and run direct calls from a shell. |
| REST | Apps, automations, and backend services | Bearer API key over HTTP | Language-agnostic integration with typed request payloads and structured responses. |

## Getting Started

### 1. Connect via MCP (one command, no API key needed)

```bash
# Claude Code
claude mcp add toolrouter -- npx -y toolrouter-mcp

# Codex CLI
codex mcp add toolrouter -- npx -y toolrouter-mcp

# All others (JSON config for Cursor, Windsurf, Cline, VS Code, Gemini CLI, Claude Desktop)
{"mcpServers":{"toolrouter":{"command":"npx","args":["-y","toolrouter-mcp"]}}}
```

Auto-provisions a free API key on first use. Free tools work immediately. For paid tools, visit the claim URL to add credits.

### 2. Or use the CLI

```bash
npx -y toolrouter-mcp tools                          # list tools
npx -y toolrouter-mcp search "screenshots"           # search
npx -y toolrouter-mcp call seo analyze_page --url https://example.com
```
