dsh-anysearch

An AnySearch-backed WebSearchProvider plugin for DeepSeek Harness (ctx.web). It calls AnySearch's MCP-style POST /mcp JSON-RPC endpoint with the search tool and parses the rendered Markdown result blocks into the harness web capability seam's normalized WebSearchResult.

Features

• Web search for the harness web_search tool through the AnySearch API
• No API key required — anonymous access works at lower rate limits; the provider stays available either way
• Settings card in the official Web GUI — configure the API key and endpoint under Settings → Plugins → AnySearch
• Credential-first key handling — keys go through the credentials domain, never into the settings file
• Vertical search support — finance, code, and other AnySearch domains via static config
• Per-search re-resolution — a changed key or endpoint takes effect on the next search, no restart

This is an implementation plugin: it registers a provider into ctx.web, it does not own the ctx.web key and it does not register a model-facing tool (that is @deepseek-ai/dsh-tool-web). It is a function/namespace plugin (inject: ['web']) that registers its backend, not a default-export service.

Requirements

• DeepSeek Harness 0.1.0-rc.6 or newer (the @deepseek-ai/dsh-* peer packages this plugin targets are published on npm at 0.1.0-rc.6).

Install

From a DeepSeek Harness profile (e.g. web):

dsh plugin --profile web add dsh-anysearch

Then route the model-facing web_search tool through the AnySearch provider by editing the profile's cordis.patch.yml:

- id: web
  config:
    searchProvider: anysearch

- insert:
    - id: web-search-anysearch
      name: 'dsh-anysearch'

The official Web GUI ships an AnySearch settings card (Settings → Plugins → Plugin configuration), which appears once the plugin is installed and exposes the API key and endpoint for configuration.

API key

1. Create a free key at https://anysearch.com/console/api-keys.
2. Configure it in the Web GUI (Settings → Plugins → Plugin configuration → AnySearch → API key), or export ANYSEARCH_API_KEY in the launch environment, or write it to $DSH_HOME/.env.
3. Restart dsh web if you changed the environment (the launch environment is a frozen boot-time snapshot).

Without a key the provider works anonymously at lower rate limits.

Config

Key	Default	Meaning
apiKey	(unset)	Literal AnySearch API key; prefer apiKeyEnv so no secret enters configuration files. Empty/absent → anonymous access (lower rate limits); the provider stays available either way.
apiKeyEnv	ANYSEARCH_API_KEY	Credential reference resolved for each search through the credentials domain, falling back to the launch environment (process > project .env > $DSH_HOME/.env).
baseURL	https://api.anysearch.com	Endpoint base; /mcp is appended. An unparseable value makes the provider unavailable.
domain	(unset)	Optional vertical-domain name (finance, code, …); sent as AnySearch's domain. Pairs with subDomain.
subDomain	(unset)	Optional vertical sub-domain; sent as AnySearch's sub_domain. Requires domain.
subDomainParams	(unset)	Optional structured parameters required by a chosen sub-domain; sent as AnySearch's sub_domain_params.
numResults	(unset)	Default result count when a request carries no maxResults. Unset sends no default. Must be a positive integer.

- id: web-search-anysearch
  name: 'dsh-anysearch'
  config:
    apiKeyEnv: ANYSEARCH_API_KEY

The plugin also installs its settings section (web-search-anysearch), which the Web client's Plugins page exposes as the AnySearch card: the key is written through the credentials domain (never into the settings file) and the endpoint can be overridden there. A section edit takes effect on the next search without a restart.

How it works

AnySearch's search tool returns rendered Markdown, not structured JSON, so this provider parses the result blocks (### N. title, - **URL**: url, then snippet lines) into WebSearchSources: url ← the URL line, title ← the numbered heading, snippet ← the folded body lines. A heading without a following URL line is dropped (nothing citeable), and the title is optional because a block may render without one. AnySearch returns no generated answer, so content is omitted. A request's maxResults wins over the configured numResults default and is capped at the API's limit of 10 before being sent as AnySearch's max_results; the final bound is enforced by the seam. Provider failures (HTTP errors, tool isError, network failure, unparseable or wrong-shape bodies) surface as WebError WEB_PROVIDER_ERROR; an aborted request surfaces as WEB_ABORTED. HTTP redirects are rejected before the Location target is contacted and surface as WEB_PROVIDER_ERROR.
