SwitchBord MCP

A free, live router for paid agent APIs that returns the best working sellers for a task, plus backups. It supports x402 and MPP payment protocols, allowing agents to find endpoints, list markets, and report results without the server handling payments.

find_paid_endpoint — Find a paid API seller
Advertised by the server during the last successful anonymous check.
Advertised read-onlyOpen-world

Find the best paid API endpoint (x402 / MPP) for a task right now. Returns sellers ranked by live health, speed and price, with fallbacks when several sell the same thing. Works for any task: if no group of sellers matches, it returns the closest single endpoints from the full inventory. You pay the seller directly; SwitchBord never touches money.

Connect from your client

Each snippet registers the same endpoint; pick the client you use.

This server is operated by the named third party. Listing and endpoint checks are not an endorsement or a security audit. Review the operator's permissions, terms, and data handling before connecting. How listings are checked and corrected.

Claude Code

Run this once in a terminal. It registers the remote server. Use --scope project to write .mcp.json for the repo.
Claude Code configuration
claude mcp add --transport http switchbord-mcp https://api.switchbord.xyz/mcp

Codex

Run this once. Codex stores MCP servers in ~/.codex/config.toml (or .codex/config.toml in a trusted project).
Codex configuration
codex mcp add switchbord-mcp --url https://api.switchbord.xyz/mcp

Cursor

Merge this server into .cursor/mcp.json in your project, then enable switchbord-mcp in your MCP settings.
Cursor configuration
{
  "mcpServers": {
    "switchbord-mcp": {
      "url": "https://api.switchbord.xyz/mcp"
    }
  }
}

Cline

Merge this into cline_mcp_settings.json (Cline → MCP Servers → Configure).
Cline configuration
{
  "mcpServers": {
    "switchbord-mcp": {
      "type": "streamableHttp",
      "url": "https://api.switchbord.xyz/mcp",
      "disabled": false
    }
  }
}

VS Code

Merge this server into .vscode/mcp.json. Use MCP: List Servers to start switchbord-mcp and inspect its tools.
VS Code configuration
{
  "servers": {
    "switchbord-mcp": {
      "type": "http",
      "url": "https://api.switchbord.xyz/mcp"
    }
  }
}

Gemini CLI

Run this once. It writes .gemini/settings.json in the current project; pass --scope user for ~/.gemini/settings.json.
Gemini CLI configuration
gemini mcp add --transport http switchbord-mcp https://api.switchbord.xyz/mcp

Claude Desktop

Merge this into claude_desktop_config.json (macOS: ~/Library/Application Support/Claude/, Windows: %APPDATA%\Claude\), then restart Claude Desktop.
Claude Desktop configuration
{
  "mcpServers": {
    "switchbord-mcp": {
      "url": "https://api.switchbord.xyz/mcp"
    }
  }
}

Windsurf

Merge this into ~/.codeium/windsurf/mcp_config.json, then refresh MCP in Cascade. Windsurf remote servers use serverUrl, not url.
Windsurf configuration
{
  "mcpServers": {
    "switchbord-mcp": {
      "serverUrl": "https://api.switchbord.xyz/mcp"
    }
  }
}
