Amazon API Gateway adds MCP proxy support

Posted on: Dec 2, 2025

Amazon API Gateway now supports Model Context Protocol (MCP) proxy, allowing you to transform your existing REST APIs into MCP-compatible endpoints. This new capability enables organizations to make their APIs accessible to AI agents and MCP clients. Through integration with Amazon Bedrock AgentCore's Gateway service, you can securely convert your REST APIs into agent-compatible tools while enabling intelligent tool discovery through semantic search.

The MCP proxy capability, alongside Bedrock AgentCore Gateway services, delivers three key benefits. First, it enables REST APIs to communicate with AI agents and MCP clients through protocol translation, eliminating the need for application modifications or managing additional infrastructure. Second, it provides comprehensive security through dual authentication - verifying agent identities for inbound requests while managing secure connections to REST APIs for outbound calls. Finally, it enables AI agents to search and select the most relevant REST APIs that best match the prompt context.

To learn about pricing for this feature, please see the Amazon Bedrock AgentCore pricing page. Amazon API Gateway MCP proxy capability is available in the nine AWS Regions that Amazon Bedrock AgentCore is available in: Asia Pacific (Mumbai), Asia Pacific (Singapore), Asia Pacific (Sydney), Asia Pacific (Tokyo), Europe (Dublin), Europe (Frankfurt), US East (N. Virginia), US East (Ohio), and US West (Oregon). To get started, visit Amazon API Gateway documentation.
