AWS Launches Web Answer on Amazon Bedrock AgentCore for Cited Agentic Search
AI assistants · AI coding · Enterprise AI
AWS announced the general availability of Web Answer on Amazon Bedrock AgentCore in us-east-1. The managed tool enables AI agents to receive synthesized answers with direct source citations from a natural-language query via a single Model Context Protocol call, eliminating the need for developers to maintain separate web search, retrieval, page cleaning, and attribution pipelines.
AWS has made Web Answer generally available on Amazon Bedrock AgentCore, providing a managed tool connector that handles web search, factual verification, synthesis, and citation extraction in a single request. Builders integrating AI agents via the Model Context Protocol (MCP) can query current web information without building custom search-and-retrieval pipelines. Operating through the AgentCore Gateway, Web Answer authenticates calls using AWS IAM or JWT and delegates execution to an AWS-managed backend. The connector autonomously plans parallel search queries, inspects relevant web pages to verify claims, and formats structured outputs with inline citations and source URLs. Unlike raw Web Search tools that return ranked links for client-side processing, Web Answer executes model synthesis internally across an Amazon-operated index without routing prompts to third-party search engines. Administrators can configure domain inclusion and exclusion filters at the Gateway target level, which client agents can narrow but not override. Initial deployment is available in the US East (N. Virginia) region, featuring PrivateLink support, CloudWatch monitoring, and a default per-account rate limit of 10 transactions per second.
Key takeaways
- Web Answer is generally available on Amazon Bedrock AgentCore as a managed Gateway tool returning synthesized answers with source citations via a single MCP call.
- The tool performs agentic web retrieval, parallel queries, and claim verification using an Amazon-managed web index, keeping queries within AWS infrastructure.
- Unlike Web Search tools returning raw snippets, Web Answer performs model synthesis and structured attribution internally, returning both markdown text and citation metadata.
- Available initially in us-east-1, it supports IAM/JWT authentication, AWS PrivateLink, target-level domain filtering, and an initial account limit of 10 transactions per second.
