Part of the AWS Bedrock AgentCore MCP Server MCP server. Enforce policies on this tool with Intercept, the open-source MCP proxy.
AI agents use gateway_create to create or modify resources in AWS Bedrock AgentCore MCP Server. Write operations carry medium risk because an autonomous agent could trigger bulk unintended modifications. Rate limits prevent a single agent session from making hundreds of changes in rapid succession. Argument validation ensures the agent passes expected values.
Without a policy, an AI agent could call gateway_create repeatedly, creating or modifying resources faster than any human could review. Intercept's rate limiting ensures write operations happen at a controlled pace, and argument validation catches malformed or unexpected inputs before they reach AWS Bedrock AgentCore MCP Server.
Write tools can modify data. A rate limit prevents runaway bulk operations from AI agents.

Create a new AgentCore Gateway resource. COST WARNING: Creating a gateway provisions AWS infrastructure and incurs AWS charges. Gateway invocations are billed separately per request. A workload identity is also auto-created alongside the gateway. The gateway starts in CREATING status and transitions to READY when ready for invocation. Use gateway_get to check status. The returned gatewayUrl is the endpoint for MCP invocations; tools are added via gateway_target_create. Returns the created gateway details including its ID, ARN, URL, and auto-created workload identity ARN.. It is categorised as a Write tool in the AWS Bedrock AgentCore MCP Server MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Add a rule in your Intercept YAML policy under the tools section for gateway_create. You can allow, deny, rate-limit, or validate arguments. Then run Intercept as a proxy in front of the AWS Bedrock AgentCore MCP Server MCP server.
gateway_create is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the gateway_create rule in your Intercept policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the Intercept policy for gateway_create. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
gateway_create is provided by the AWS Bedrock AgentCore MCP Server MCP server (awslabs.amazon-bedrock-agentcore-mcp-server). Intercept sits as a proxy in front of this server to enforce policies before tool calls reach the server.
