}When building MCP servers for AI agents, managing outbound IP addresses is harder than it should be
Databases, payment providers, CRM APIs, and B2B partner services all require IP whitelisting. Your MCP server tools need a consistent outbound IP to reach them.
MCP servers run in containers, serverless functions, and cloud environments. Outbound IPs rotate with deployments and scaling events. API providers reject unknown source IPs.
When infrastructure rotates IPs, your MCP tools fail silently. AI agents lose access to external resources. Debugging is difficult because errors appear as API permission denials.
European businesses handling sensitive data through MCP tools need infrastructure that aligns with GDPR requirements. AI tool traffic must respect data residency.
"Provide the IP address that will access our API."
You need a stable, predictable answer for your MCP server tools.
MCP Server
HTTPS Proxy
(Static EU IP)
External API
The external API sees one fixed EU IP address — every MCP server call.
Building MCP servers that connect AI agents to external APIs, databases, and third-party services
Connecting AI-powered features to enterprise APIs that require IP whitelisting
Managing AI infrastructure and ensuring MCP servers maintain reliable outbound connectivity
Running MCP tools in regulated industries where outbound traffic must originate from known EU IP addresses
Your MCP server runs locally or in the cloud. Outbound HTTPS requests are routed through your dedicated proxy. All requests originate from a single static EU IP. You whitelist that IP once. That's it.
Add the HTTPS_PROXY environment variable to your MCP server configuration. This works with the Model Context Protocol config format used by Claude Desktop, Cursor, Windsurf, and other MCP-compatible clients.
