## 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.

**SearchAPI.io.** 99.9% SLA on every plan and no incidents on the status page since August. MCP exposes over 100 tools with no toolsets.

## 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

### SearchAPI.io

1. Send the key as `Authorization: Bearer`, not `api_key=` in the URL
2. Connect the MCP through OAuth or the `X-MCP-Token` header, not the registry's `?token=` URL
3. Call the REST API with `engine=` when context is tight. The MCP loads over 100 tool definitions
4. Page Google results with `page`. `num` is fixed at 10
5. Pace bursts. One hour can use at most 20 per cent of the plan's monthly searches
