MCP Servers

The Model Context Protocol (MCP) is an open standard enabling models and agents to access external tools, databases, and resources. nRouter provides a secure MCP Gateway reverse proxy between AI clients and your private upstream tool servers.

Architecture & Integration

Proxies tool traffic at https://api.nrouter.ai/mcp/{server_name} with Streamable HTTP (streamable_http):

• Zero-Credit Proxying: Calls consume zero generation tokens and place no credit holds; usage adheres to key rate limits (RPM) and budget ceilings.
• SSRF & Security: Requires https://; blocks loopback, metadata, and private subnets. Upstream secrets remain encrypted at rest and masked in UI (•••7890).
• Dashboard Hubs: Manage connections in MCP Hub (/[organization]/mcp-hub, Owner/Admin write access) and browse tools in Tools Hub (/[organization]/tools-hub). MCP proxy calls consume no model tokens and rate limits are managed in the dashboard (Pay as you go: 1 server; existing: 10; Enterprise: 1,000). See API Key Management, Dashboard, and Guardrails.

Export configuration into claude_desktop_config.json, ~/.claude.json, or .cursor/mcp.json:

{
  "mcpServers": {
    "linear": {
      "url": "https://api.nrouter.ai/mcp/linear",
      "headers": { "Authorization": "Bearer sk-nrouter-xxxxxxxxxxxx" }
    }
  }
}

Tools can also be called programmatically via the nRouter SDK.
