AgentCore-Gateway

Understand the challenge that Gateway solves

We are a large organization with 50 teams developing AI agents for various business needs. Currently, each team independently manages their own tool integrations - for example, if 30 teams need to use Salesforce APIs, that's 30 separate sets of credentials to maintain and secure. Similarly, when teams need weather data, they each maintain their own API keys and tool configurations. This has created a sprawling landscape of duplicated credentials, redundant tool implementations, and excessive token usage. When our security team needs to audit API access or update credentials, they must coordinate with 50 different teams. Additionally, each team is consuming tokens to search through their own extensive tool lists, often for the same purposes. This decentralized approach has become increasingly inefficient, costly, and difficult to secure and maintain across our organization

Without Gateway:

├── 50 Teams

│   ├── Each managing same third-party credentials

│   ├── Each maintaining separate tool lists

│   ├── Multiple security audit points

│   └── Redundant token usage across teams

Solution with Gateway:

Centralized Security

Single point for credential management

• One security audit surface

• Controlled access policies

• Smart Tool Discovery

Semantic search across available tools

• Returns most relevant tools (10 vs 1000)

• Reduces token consumption

• Better tool recommendations

The Gateway acts as a translation layer that converts OpenAPI specifications into MCP-compatible tools, handling authentication, request routing, and protocol conversion automatically.

Modern enterprises rely on hundreds of REST APIs for their daily operations, but integrating these APIs with AI agents traditionally requires custom integration code, manual protocol conversion, and complex authentication management. AgentCore Gateway fundamentally transforms this by automating API integration through OpenAPI specification parsing, standardizing access via the MCP protocol, and centralizing authentication management.

Additional Benefits:

Standardized tool interfaces

• Usage analytics across teams

• Cost optimization

• Version control of tool integrations

• Simplified compliance management

Think of it like:

Before: 50 teams each having their own key to the same door

After: One secure entrance, intelligent directory service

Real Impact:

Before Gateway:

Team A: Uses 100 tokens to search 1000 tools

Team B: Uses 100 tokens to search same 1000 tools

...50 times

After Gateway:

• Central search: 100 tokens total

• Returns: Most relevant 10 tools

• Benefits all 50 teams

Also Provides:

Tool usage patterns

• Performance metrics

• Cost allocation

• Governance controls

• API standardization

AgentCore Gateway simplifies agent tool integration in three key ways:

1. Universal MCP Support: Instantly make your tools compatible with any agent framework by exposing them through AgentCore Gateway's MCP standard

2. Simple REST Integration: Transform existing REST services into agent tools by just adding them as AgentCore Gateway targets

3. Lambda Flexibility: Expose Lambda functions as MCP endpoints that can call any API - demonstrated here with a function that checks warranty status

AgentCore Gateway
populates the Lambda context with the name of the tool to invoke
parameters passed to the tool are provided in the Lambda event
