## MCP tools (4)

### `search` (~635 tokens)

Broad web search across the SearXNG instance's full enabled engine pool.

Use this for general-purpose queries when you don't have a specific source preference. Returns a merged, deduplicated result list from across this instance's enabled engines — actual yield depends on which engines respond at query time.

Knobs:
  • pages=N (max 5) — fetch multiple pages and merge for more results in one call.
  • format='full' — full result objects with metadata; default 'compact' is token-efficient.
  • time_range — narrow to recent results (note: not all engines support this — see field doc).

When to reach for a different tool:
  • search_on_engines    — you want specific sources (e.g. just ArXiv + PubMed)
  • search_by_category   — you want all engines in a category (e.g. all science)

Input parameters:

- `format` (string): 'compact' (default) returns only url/title/content/engine for each result — typically much smaller, recommended for ranking and triage. 'full' adds: relevance score, publishedDate, the list of all en…
- `language` (string): Language filter, e.g. 'en', 'fr', 'de', 'pt-BR', or 'all' to disable filtering. If omitted, the SearXNG instance's configured default applies (NOT autodetected from the query, despite what the name s…
- `pageno` (integer): 1-indexed starting page number. Default 1. Higher pages fetch additional results from each engine, deduplicated against earlier pages by URL. Per-page yield drops sharply after the first 1-2 pages as…
- `pages` (integer): Multi-page fanout: fetch this many consecutive pages in parallel and merge with URL-based dedup. Default 1. Combines with pageno: pageno=3 + pages=2 fetches pages 3 and 4. Diminishing returns past pa…
- `query` (string, required): Plain-language search query. Forwarded to each engine's native parser; engine-specific operators (e.g. site:, filetype:) are passed through unchanged.
- `safe_search`: Safe-search level. 0 = off, 1 = moderate, 2 = strict. If omitted, the SearXNG instance's configured default applies (often 0 for self-hosted, but not guaranteed).
- `time_range` (string): Filter to results published within this time window. WARNING: not all engines implement time-range filtering — some (notably academic engines) return ZERO results when this is set instead of ignoring…

### `search_on_engines` (~619 tokens)

Search using ONLY the specified engines (e.g. engines: ["arxiv", "duckduckgo"]).

Use when you have a specific source preference instead of the broad `search` tool.

NOTE: this instance's live engine/category list is currently unavailable — SearXNG was unreachable when the server started. Names you pass are forwarded and validated once SearXNG is reachable; restart the server after SearXNG is up to see the enabled list here.

Multi-page fanout (pages=N) and other knobs work the same as the broad `search` tool.

Input parameters:

- `engines` (array, required): Engine names to use, lowercase. Multiple engines run in parallel and results are merged. Must match this instance's enabled engines (the available list is enumerated in this tool's description above).
- `format` (string): 'compact' (default) returns only url/title/content/engine for each result — typically much smaller, recommended for ranking and triage. 'full' adds: relevance score, publishedDate, the list of all en…

### `search_by_category` (~611 tokens)

Search within one or more categories — runs every engine tagged with each (e.g. categories: ["science"]).

Use when you want broad coverage of a content type without enumerating engines.

NOTE: this instance's live engine/category list is currently unavailable — SearXNG was unreachable when the server started. Names you pass are forwarded and validated once SearXNG is reachable; restart the server after SearXNG is up to see the enabled list here.

Multi-page fanout (pages=N) and other knobs work the same as the broad `search` tool.

Input parameters:

- `categories` (array, required): Category names to constrain the search. SearXNG runs every engine tagged with these categories. The available categories are enumerated in this tool's description above.
- `format` (string): 'compact' (default) returns only url/title/content/engine for each result — typically much smaller, recommended for ranking and triage. 'full' adds: relevance score, publishedDate, the list of all en…

### `web_url_read` (~690 tokens)

Fetch a URL and convert its HTML content to clean Markdown.

Use after `search` (or its variants) when you have a URL and want the
actual page text, not just the search snippet. Lightweight HTTP +
HTML→Markdown — handles ~80% of the static-HTML web (Wikipedia, docs
sites, blogs, news, GitHub READMEs).

What this DOES NOT handle:
  • JavaScript-rendered pages (React/Vue/Angular SPAs) — content loads
    after the initial HTML, which we don't execute. Returns minimal or
    empty markdown for these.
  • Bot-protected pages (Cloudflare challenge, captcha) — typically
    fail with HTTP 403/503.
  • Binary resources (PDF, images, archives) — returns an explanatory
    hint instead of garbled bytes.

For those cases, fall back to a Chromium-backed reader (e.g. Crawl4AI
exposed via the SearXNG-Compose `reader` profile).

Token-efficient extraction modes (priority order — first one set wins):
  • readHeadings:true        — returns ONLY the heading list (hierarchical
                                 TOC). Cheapest survey of a long page.
  • section:'<text>'         — returns content under first matching
                                 heading, up to the next same-or-higher
                                 heading. Use after readHeadings to jump.
  • paragraphRange:'3-7'     — 1-indexed paragraph slice; supports 'N'
                                 (single) or 'N-M' (range).
  • startChar + maxLength    — character window pagination. Response
                                 includes total_length and truncated so
                                 you can plan follow-up calls.

If no extraction mode is set, returns the full Markdown.

Recommended workflow for long pages:
  1\. web_url_read(url, readHeadings: true)            ← TOC scan
  2\. web_url_read(url, section: '<chosen heading>')   ← targeted read
Far more token-efficient than fetching the full page up front.

Input parameters:

- `maxLength` (integer): Maximum characters to return. Use with startChar for paginated reading; the response includes `total_length` and `truncated` so you can plan follow-up calls.
- `paragraphRange` (string): 1-indexed paragraph range, syntax 'N' or 'N-M' (e.g. '3-7' for paragraphs 3–7, '5' for paragraph 5 alone). Useful for sequential reading of long pages without re-fetching.
- `readHeadings` (boolean): When true, returns ONLY the page's heading list as a hierarchical TOC (token-cheap survey). Pair with a follow-up call using `section` to read the chunk you actually want.
- `section` (string): Substring match against headings (case-insensitive). Returns content under the FIRST heading containing this text, up to the next heading at the same or higher level. Use after readHeadings to read a…
- `startChar` (integer): Character offset where extraction begins. Default 0.
- `url` (string, required): HTTP(S) URL to fetch and convert to Markdown. Static pages only — for JavaScript-rendered SPAs and bot-protected sites, use a Chromium-backed reader instead.
