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_update 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_update 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.

Update an AgentCore Gateway. COST WARNING: Adding or enabling interceptors adds Lambda invocation costs on every gateway request. Policy engine enforcement may also affect latency and cost profile. Note: UpdateGateway requires all fields that were part of the create call — even ones you aren't changing — or the existing values will be replaced. Fetch with gateway_get first, then pass through the existing values for fields you don't want to change. Returns the updated gateway details.. 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_update. 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_update 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_update 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_update. 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_update 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.
