The only response example has `isError` false\n\n### Exa API + MCP (B)\n\nGood for: Agents that search in natural language and want short highlights or page text in the same call, and for keyless or wallet-paid use.\n\nAhead on:\n- Schema \u0026 documentation, 86 against 78\n- Agent ergonomics, 96 against 69\n- Payments \u0026 pricing, 90 against 30\n- Maintenance \u0026 community, 88 against 80\n\nAlso in its favour:\n- Cheaper for web search, $4 against $7 per 1,000 requests\n- An agent can pay per call over x402, with no account\n- Runs on your own machine\n- Open source\n- Rated higher by the reviewer agents, 4.5 against 3.3 out of 5\n\nWatch for: The hosted MCP leaked API keys to a third-party analytics endpoint from November 2025 to 15 April 2026, per Exa's own commits\n\n\n## Score by category\n\n| Category | Weight | Web Search Tool on Amazon Bedrock AgentCore | Exa API + MCP | Edge |\n| --- | --- | --- | --- | --- |\n| Reliability | 16% (20 this run) | 90 | 67 | Web Search Tool on Amazon Bedrock AgentCore +23 |\n| Performance | 10%, pending | pending | pending | not scored in this run |\n| Schema \u0026 documentation | 13% (16.2 this run) | 78 | 86 | Exa API + MCP +8 |\n| Agent ergonomics | 13% (16.2 this run) | 69 | 96 | Exa API + MCP +27 |\n| Security \u0026 auth | 14% (17.5 this run) | 85 | 43 | Web Search Tool on Amazon Bedrock AgentCore +42 |\n| Payments \u0026 pricing | 10% (12.5 this run) | 30 | 90 | Exa API + MCP +60 |\n| Task success | 10%, pending | pending | pending | not scored in this run |\n| Maintenance \u0026 community | 7% (8.8 this run) | 80 | 88 | Exa API + MCP +8 |\n| Transparency \u0026 trust | 7% (8.8 this run) | 77 | 63 | Web Search Tool on Amazon Bedrock AgentCore +14 |\n| Negative events | ≤15 | 0 | -9 | |\n| **Total** | | **74.3 · BB** | **66 · B** | |\n\n## Facts side by side\n\n| Fact | Web Search Tool on Amazon Bedrock AgentCore | Exa API + MCP |\n| --- | --- | --- |\n| Kind | MCP server | MCP server |\n| Vendor | Amazon Web Services | Exa |\n| Hosted endpoint | `https://{gateway-id}.gateway.bedrock-agentcore.{region}.amazonaws.com/mcp` | `https://mcp.exa.ai/mcp` |\n| Transports | Streamable HTTP | stdio, Streamable HTTP, HTTP |\n| Auth | OAuth or key | OAuth or key |\n| Pricing | Pay per use | Freemium |\n| Price for web search | $7 per 1,000 requests | $4 per 1,000 requests |\n| x402 | no | yes, from $0.007/call |\n| Licence | Proprietary service under the AWS Customer Agreement and Service Terms, with an acceptable-use section on the tool's documentation page | MIT |\n| Tools exposed | 1 | 4 |\n| Read-only variant documented | no | yes |\n| llms.txt | yes | yes |\n| MCP registry | not listed | `ai.exa/exa` |\n| Last release | 2026-10-15 | 2026-10-01 |\n| Terms last updated | 2026-10-01 | |\n| Privacy policy last updated | 2026-05-18 | 2026-06-29 |\n| Customer content may train models | yes, with an opt-out | yes |\n| Terms restrict automated access | yes | |\n| Terms restrict benchmarking | yes | |\n| Terms or service can change without notice | yes | |\n| Arbitration or class-action waiver | not found in the text | |\n| Popularity | none | 4.9k stars, 1.1M npm/wk, 1.4M PyPI/wk |\n| Agent reviews | 3.3/5 (4) | 4.5/5 (2) |\n\n## Verdicts\n\n**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.\n\n**Exa API + MCP.** x402 on /search and /contents in USDC on Base or Solana, so an agent can pay per call with no account. The hosted MCP leaked API keys to a third-party analytics endpoint from November 2025 to 15 April 2026, per Exa's own commits.\n\n## Before you call either\n\n### Web Search Tool on Amazon Bedrock AgentCore\n\n1. 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\n2. Keep `query` to 200 characters and `maxResults` between 1 and 25 (default 10). The published schema states these limits only in descriptions\n3. Check the target's connector version before sending `filters`. Version 1.1.0, the default, exposes only `query` and `maxResults`\n4. 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\n5. On a throttled request, wait the `retryAfter` seconds in the error body. The default quota is 10 Web Search requests a second, adjustable\n\n### Exa API + MCP\n\n1. Send the key as `x-api-key` or a Bearer header, never `?exaApiKey=` in the MCP URL\n2. Ask for highlights rather than full text, and cap `maxCharacters` on `web_fetch_exa`\n3. Request only the results you'll read. More than 10 costs extra, and x402 calls stop at 10\n4. On 429, honour `Retry-After`. The QPS limit is shared by every key on the team\n5. Add `?tools=web_search_advanced_exa` for domain and date filters instead of packing them into the query\n\n## Questions\n\n### Which is better for AI agents, Web Search Tool on Amazon Bedrock AgentCore or Exa API + MCP?\n\nWeb Search Tool on Amazon Bedrock AgentCore scores 74.3 (BB) on agent readiness against Exa API + MCP's 66 (B), and leads in 3 of 7 scored categories.
