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.

Linkup

Per-call prices from $0.005, and no credit taken for errors, missing parameters or empty results. 429 covers both exhausted credit and rate limiting, with no Retry-After.

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

Linkup

  1. On 429, check the credit balance before backing off. The same code means out of credit
  2. Pass reasoningDepth: "S" to research unless you need more. The MCP default is L at $1.50
  3. Start with depth=fast and outputType=searchResults. Deep costs $0.05, ten times as much
  4. Send the key as an Authorization: Bearer header, not ?apiKey= or a command-line argument
  5. Poll linkup-get-research with the task id. Research runs take minutes
