## Which one, for what

### Web Search Tool on Amazon Bedrock AgentCore (BB)

Good for: A team already on AWS that wants agents to search the web through a governed MCP gateway, with owner-set domain lists, IAM or OAuth control and queries kept inside AWS.

Ahead on:
- Reliability, 90 against 75
- Security & auth, 85 against 45
- Transparency & trust, 77 against 65

Also in its favour:
- Free to start without a card

Watch for: No error responses for the tool are documented. The only response example has `isError` false

### Parallel Search and Task APIs (BB)

Good for: Agents that mix quick search with long research or enrichment jobs and want one vendor and one bill.

Ahead on:
- Schema & documentation, 94 against 78
- Agent ergonomics, 87 against 69
- Payments & pricing, 75 against 30
- Maintenance & community, 87 against 80

Also in its favour:
- Cheaper for web search, $1 against $7 per 1,000 requests

Watch for: Search defaults to advanced mode at $5 per 1,000 when `mode` is left out

## 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
