Verdicts

Web Search Tool on Amazon Bedrock AgentCore

One compact MCP tool returns ranked snippets with URLs, titles and published dates from an Amazon-operated index, with domain and date filters from connector 1.2.0, at $7 per 1,000 queries. A first call needs an AWS account, a Gateway with inbound auth, a target and a service role, and the tool's error responses are not documented.

Parallel Search and Task APIs

Fast-mode search at $1 per 1,000 with 10 excerpted results, and a keyless two-tool Search MCP annotated read-only. Search defaults to advanced mode at $5 per 1,000 when mode is left out, and the Customer Terms allow training on inputs and outputs.

Before you call either

Web Search Tool on Amazon Bedrock AgentCore

  1. Call tools/list on the gateway and take the tool's name from it. AWS's call examples name gateway tools by target and tool
  2. Keep query to 200 characters and maxResults between 1 and 25 (default 10). The published schema states these limits only in descriptions
  3. Check the target's connector version before sending filters. Version 1.1.0, the default, exposes only query and maxResults
  4. Keep each result's URL and title with any answer built from it. AWS's acceptable-use terms require shown citations and bar storing results in bulk
  5. On a throttled request, wait the retryAfter seconds in the error body. The default quota is 10 Web Search requests a second, adjustable

Parallel Search and Task APIs

  1. Pass mode: "fast" on every API search. Without it you pay the advanced rate. On an authenticated MCP connection, pin it with ?mode=fast
  2. Create Task runs with max_retries=0 and check for an existing run before retrying
  3. Give an objective plus two or three short search_queries. That's what ranks the excerpts
  4. On 402, check available balance rather than total. Running tasks reserve credit
  5. Ask for zero data retention or use the EU endpoint before sending private queries. The default terms allow training on them
