Provenance No attestation
The registry publishes no build provenance for this version, so there is nothing to verify.

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
fetch_csdn_article ~84
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.
| Name | Type | Req | Description |
|---|---|---|---|
| url | string | yes | HTTPS article URL on blog.csdn.net |
No output schema declared.
No examples provided.
fetch_github_readme ~85
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.
| Name | Type | Req | Description |
|---|---|---|---|
| url | string | yes | GitHub repository URL (e.g., https://github.com/owner/repo) |
No output schema declared.

fetch_juejin_article ~78
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.
| Name | Type | Req | Description |
|---|---|---|---|
| url | string | yes | Juejin article URL |
No output schema declared.
No examples provided.
free_extract ~198
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.
| Name | Type | Req | Description |
|---|---|---|---|
| max_length | number | – | Maximum characters to return (default: 5000). Content beyond this limit is truncated. Increase for long articles, decrease for quick snippets. |
| url | string | yes | URL to extract content from. Supports any public web page URL (http/https). For best results, use a complete URL including the protocol (https://). |
No output schema declared.
No examples provided.
free_search ~225
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.
| Name | Type | Req | Description |
|---|---|---|---|
| engines | array | – | Search engines to use (default: duckduckgo + sogou). Free engines work without API keys. Optional API engines require their corresponding environment-variable credentials. For Chinese results, includ… |
| limit | integer | – | Number of results to return (1-50). Default 10. Higher values increase token usage. |
| query | string | yes | Search query string. Use natural language (e.g., "latest AI news 2026"). For Chinese coverage, include Sogou or Baidu in engines. |
| Name | Type | Req | Description |
|---|---|---|---|
| cache_hit | boolean | – | – |
| detected_language | string | – | – |
| engines | array | yes | – |
| meta | object | yes | – |

free_search_advanced ~317
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.
| Name | Type | Req | Description |
|---|---|---|---|
| count | integer | – | Number of results (1-20) |
| enrich | boolean | – | Enable content enrichment (extract full page for low-confidence results) |
| enrich_max | number | – | Max results to enrich per search |
| exclude_domains | array | – | Exclude these domains |
| include_domains | array | – | Only search these domains |
| language | string | – | Language preference |
| min_confidence | number | – | Minimum source-reliability confidence (0-1). Legacy values 2-3 are treated as min_source_count. |
| min_source_count | integer | – | Minimum independent upstream provider families; the input contract is capped at 12 for compatibility |
| query | string | yes | Search query |
| time_range | string | – | Deprecated compatibility field; returns UNSUPPORTED_FILTER because general-search recency is not enforced end to end |
| waterfall | boolean | – | Enable waterfall progressive search (saves engine calls) |
| waterfall_min_confidence | number | – | Minimum average confidence to stop waterfall early |
| waterfall_min_results | number | – | Minimum results per phase for waterfall confidence check |
| Name | Type | Req | Description |
|---|---|---|---|
| cache_hit | boolean | – | – |
| detected_language | string | – | – |
| engines | array | yes | – |

| security_note | string | yes | – |
No examples provided.
search_with_synthesis ~178
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.
| Name | Type | Req | Description |
|---|---|---|---|
| count | integer | – | Number of search results to gather (1-20) |
| language | string | – | – |
