Feature & Specification Comparison
Tools & Capabilities Breakdown
Agent Search MCP Tools (7)
free_search
Quick public-web search for current facts and discovery.
Use free_search_advanced for verification or domain filters. Use free_extract for one selected URL.
Returns compact multi-source evidence with confidence, relevance, source_count, stop_reason, evidence_budget, and partialFailures. Provider families are counted once even when several adapters use the same upstream. Optional API providers run only when credentials and policy allow.
@readOnly true @idempotent true — makes outbound HTTP requests to configured search engines. Injection detection and SSRF protection active.
free_search_advanced
Verification-oriented search with domain filters and waterfall fallback.
Use for claim checking, Chinese-source search, or publisher restrictions. Start with free_search for quick discovery. The response exposes source_count, stop_reason, evidence_budget, and partialFailures.
@readOnly true @idempotent true — runs waterfall progressive search across policy-allowed engines. Makes outbound HTTP requests to search engines and optionally to Jina Reader for content enrichment.
free_extract
Extract one selected URL into clean Markdown.
Use after search when snippets are insufficient, or for a URL supplied by the user. It fetches one page; it does not search or bulk-extract URLs.
Behavior: Makes an outbound HTTP request to Jina Reader (r.jina.ai) which fetches and converts the page to markdown. Has SSRF protection: blocks private IPs, localhost, and metadata endpoints. 10s request timeout — pages exceeding this will fail with a timeout error. HTTP errors (4xx, 5xx) are returned as structured error responses.
