dsh-web-search-searxng

SearXNG-backed search provider plugin for DeepSeek Harness.

Registers a WebSearchProvider into ctx.web so that the existing web_search model tool routes through your SearXNG instance. No auth, no API key, no model calls — just a plain HTTP GET against SearXNG's JSON endpoint.

Status

⚠️ Not yet published to npm. The CI/CD workflow builds on every push and publishes automatically when a v* tag is pushed. Once the first release is cut:

npm install @jaco-tech/dsh-web-search-searxng

Configure

Add to your DSH profile's cordis.patch.yml:

- insert:
    - id: web-search-searxng
      name: '@jaco-tech/dsh-web-search-searxng'
      config:
        baseURL: 'http://your-searxng-instance:8888'
        # Optional filters:
        language: 'en'
        categories: 'general'
        timeRange: ''

Optionally pin ctx.web to use this provider explicitly:

- replace:
    - id: web
      config:
        searchProvider: searxng

How it works

This is a Cordis plugin that implements the WebSearchProvider interface from @deepseek-ai/dsh-web:

export const name = "web-search-searxng"
export const inject = ["web"]

export function apply(ctx, config) {
  ctx.web.registerSearchProvider({
    id: "searxng",
    available() { /* URL.canParse(config.baseURL) */ },
    async search(request, signal) {
      // GET /search?q=&format=json
      // maps response to WebSearchResult
    }
  })
}

The existing @deepseek-ai/dsh-tool-web consumer calls ctx.web.search() — your SearXNG instance serves the results automatically.

Provider interface

Method	Behavior
`available()`	Returns `true` when `baseURL` is a valid URL
`search(request, signal?)`	`GET /search` with `q`, `format=json`, optional `language`/`categories`/`time_range` params. Dedupes results by URL. Surfaces `answers` and `infoboxes` as provider-generated answer text.

Upstream

This plugin communicates with SearXNG via its JSON API (/search?format=json). SearXNG is a free internet metasearch engine which aggregates results from more than 70 search services. You need a running SearXNG instance to use this plugin.
