Agent Search mcp

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.

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.

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.

Fetch README content from a GitHub repository. Best for: Getting project documentation quickly. Not recommended for: Non-GitHub URLs — use free_extract instead. @readOnly true @idempotent true — makes outbound HTTP requests to raw.githubusercontent.com.

Fetch content from a CSDN blog article. Best for: Chinese developer blog content on CSDN. Not recommended for: Other Chinese sites — use free_extract instead. @readOnly true @idempotent true — makes outbound HTTP requests to the CSDN article URL.

Fetch content from a Juejin article. Best for: Chinese developer articles on Juejin. Not recommended for: Non-Juejin content — use free_extract instead. @readOnly true @idempotent true — makes outbound HTTP requests to juejin.cn API.

Opt-in deep search with waterfall verification and content enrichment. Returns structured results plus a prompt_hint; it does not call an external LLM. Use when multi-source evidence needs a synthesis handoff. free_search is the default for discovery; this path uses more tokens and network time. @readOnly true @idempotent true — runs waterfall search across free+paid engines with content enrichment.
