@nhtio/adk/batteries/tools/searxng

Factory for a configured SearXNG metasearch tool.

Remarks

Unlike the other bundled tool categories — every one of which exports a ready-made, stateless Tool constant — the SearXNG battery exports a factory, createSearxngSearchTool. A search tool has to talk to a specific SearXNG instance, usually behind custom authentication, so it needs per-deployment configuration (a base URL and headers) that cannot be baked in at module load.

Because this module exports a factory rather than a Tool instance, it MUST NOT be bulk-registered via Object.values(batteries). Call the factory first, then register the returned tool: new ToolRegistry([createSearxngSearchTool({ instanceUrl })]).

Interfaces

Interface	Description
SearxngRequestContext	Mutable context handed to each input-pipeline stage before the HTTP request is sent.
SearxngResponseContext	Mutable context handed to each output-pipeline stage after the response JSON is parsed.
SearxngResult	A single normalised SearXNG result. SearXNG result items are deliberately untyped upstream, so every field except a best-effort title/url is optional.
SearxngToolConfig	Configuration for createSearxngSearchTool.

Type Aliases

Type Alias	Description
SearxngHeaders	A static set of request headers (used for custom authentication).
SearxngHeadersResolver	A resolver returning request headers, sync or async. Use this form when the auth token is refreshable — the resolver runs on every search, so a fresh token can be minted per call.
SearxngInputMiddlewareFn	An input-pipeline stage. Onion middleware over SearxngRequestContext.
SearxngOutputMiddlewareFn	An output-pipeline stage. Onion middleware over SearxngResponseContext.
SearxngResultFormat	The output shape the tool serialises. either lets the model pick per call.

Functions

Function	Description
createSearxngSearchTool	Create a configured SearXNG search Tool.
