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 →
raw_request Raw Custom Search API call ~192
Escape hatch: performs a GET against any Custom Search JSON API path and returns the raw, unnormalized response envelope (queries.request/nextPage, searchInformation, promotions, context, items[] with htmlSnippet/htmlTitle/formattedUrl and the full pagemap). Use it for parameters the typed tools don't expose (lowRange/highRange, c2coff, hq, fields) — e.g. path "customsearch/v1?q=test&num=3&fields=items(title,link)". The API key is added automatically (in a header, never the URL) and the configured engine id is filled in when the path has no cx parameter. The API has GET endpoints only, so nothing here can modify data.
| Name | Type | Req | Description |
|---|---|---|---|
| path | string | yes | API path with query string, relative to https://customsearch.googleapis.com — e.g. "customsearch/v1?q=hello&num=3". |
No output schema declared.
No examples provided.
search Web search ~777
Web search through your Google Programmable Search Engine (Custom Search JSON API). Returns query, total_results (Google's estimate — it can shrink while paging), search_time_seconds, corrected_query (spelling suggestion; results are still for the original query), next_start/previous_start page cursors, and items[] with title, url, display_link, snippet, mime/file_format and (with include_pagemap) pagemap metadata. Coverage is the engine's configuration: an engine listing specific sites searches only those; open-web search needs "Search the entire web" enabled in its control panel — results still differ from google.com. Max 10 results per call and 100 per query: paginate by passing next_start as start. Each call costs one unit of the daily quota (free tier 100/day), so prefer one precise query over many broad ones. Note: this is Programmable Search, NOT Google Search Console — it cannot report how your own site is indexed or ranked.
| Name | Type | Req | Description |
|---|---|---|---|
| country | string | – | Geolocation bias — rank results as if searching from this country, e.g. "de". Soft signal. |
| country_restrict | string | – | Hard filter — only documents Google attributes to this country, e.g. "DE". |
| date_restrict | string | – | Only results from the last N days/weeks/months/years: "d7", "w2", "m6", "y1", ... |
| engine_id | string | – | Programmable Search Engine id (cx) to search with, overriding the configured GOOGLE_CUSTOM_SEARCH_ENGINE_ID. Omit to use the configured engine. |
| exact_terms | string | – | A phrase every result must contain. |
| exclude_terms | string | – | A word or phrase no result may contain. |
| file_type | string | – | Only files of this type, e.g. "pdf", "xlsx", "svg". |
| filter_duplicates | boolean | – | Google's duplicate-content filter (default on). false returns near-duplicate results too. |
| include_pagemap | boolean | – | Attach each result's raw pagemap (OpenGraph/metatags/thumbnails and other structured page data). Verbose — leave off unless you need page metadata. |
| interface_language | string | – | Interface language used to interpret the query, e.g. "de". Improves non-English relevance. |
| language | string | – | Only results in this language, e.g. "en", "de", "zh-CN". |
| num | integer | – | Results per page, 1..10 (API maximum 10; default 10). |
| or_terms | string | – | Space-separated words — each result must contain at least one of them. |
| query | string | yes | The search query, Google syntax included (quotes, site:, filetype:, OR, -exclusions). |
| rights | string | – | License filter: cc_publicdomain, cc_attribute, cc_sharealike, cc_noncommercial, cc_nonderived (combine with |). |
| safe | string | – | Safe search: active filters adult content, off (the API default) does not. |
| site_search | string | – | A site or domain to include or exclude, e.g. "example.com" — pair with site_search_filter. |
| site_search_filter | string | – | include = only results from site_search, exclude = everything but it. Default include. |
| sort | string | – | Sort expression, e.g. "date" for newest-first. Omit for relevance (usually better). |
| start | integer | – | 1-based index of the first result — use next_start/previous_start from the previous page. The API serves at most 100 results per query, so start + num - 1 must stay <= 100 (enforced: a wider window i… |

search_images Image search ~815
Image search through your Google Programmable Search Engine (searchType=image). Works only when the engine has "Image search" enabled in its control panel — otherwise the API answers 400. Each item's url is the image file itself; image.context_url is the page hosting it, with width/height/byte_size and a thumbnail_url (plus its dimensions) for previews. Everything else matches the search tool: same filters (language/country, safe search, site include/exclude, date_restrict, file_type, rights — use rights for reusable images), same pagination (max 10 per call, 100 per query, paginate via next_start), same quota (one unit per call). Image-only filters: size (icon..huge), type (clipart/face/lineart/stock/photo/animated), color_type (mono/gray/color/trans) and dominant_color.
| Name | Type | Req | Description |
|---|---|---|---|
| color_type | string | – | mono = black & white, trans = transparent background. |
| country | string | – | Geolocation bias — rank results as if searching from this country, e.g. "de". Soft signal. |
| country_restrict | string | – | Hard filter — only documents Google attributes to this country, e.g. "DE". |
| date_restrict | string | – | Only results from the last N days/weeks/months/years: "d7", "w2", "m6", "y1", ... |
| dominant_color | string | – | Prefer images dominated by this color. |
| engine_id | string | – | Programmable Search Engine id (cx) to search with, overriding the configured GOOGLE_CUSTOM_SEARCH_ENGINE_ID. Omit to use the configured engine. |
| exact_terms | string | – | A phrase every result must contain. |
| exclude_terms | string | – | A word or phrase no result may contain. |
| file_type | string | – | Only files of this type, e.g. "pdf", "xlsx", "svg". |
| filter_duplicates | boolean | – | Google's duplicate-content filter (default on). false returns near-duplicate results too. |
| include_pagemap | boolean | – | Attach each result's raw pagemap (OpenGraph/metatags/thumbnails and other structured page data). Verbose — leave off unless you need page metadata. |

| query | string | yes | The search query, Google syntax included (quotes, site:, filetype:, OR, -exclusions). |

| safe | string | – | Safe search: active filters adult content, off (the API default) does not. |

| size | string | – | Image size class, from icon to huge. |
