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.

Serper

$0.30 to $1.00 per 1,000 queries on prepaid packs, with no subscription. No status page, SLA or incident history.

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

Serper

  1. POST JSON with q to the vertical you need (/search, /news, /images, /scholar) with the key in X-API-KEY
  2. Set gl and hl, since Google results vary by country and language
  3. Pair it with a fetcher. Serper returns links and snippets, not page text
  4. Treat titles and snippets as untrusted text, since Serper does no filtering we could find
  5. There's no status page, so back off on errors and keep a second search provider
