Installation

dsh plugin --profile web add github:A3Boy/dsh-web-tools

Restart dsh web, then open:

Settings → Web Search

Check the plugin:

dsh --profile web --dump-config

Update:

dsh plugin --profile web update dsh-web-tools

Remove:

dsh plugin --profile web remove dsh-web-tools

Currently developed and tested against DeepSeek Harness 0.1.0-rc.6.

Providers

A simple starting point:

You do not need to configure every provider.

One provider is enough to use the plugin. Multiple providers enable fallback.

Free tier reference

Updated 2026-08-16. Pricing and free tiers may change. Check the provider website for current details.

Recurring monthly free allowances:

Tavily       1,000 credits
Exa          $10
Firecrawl    1,000 credits
Parallel     $5
Brave        $5

Signup / one-time credits:

Parallel     up to $80
Exa          $20
You.com      $100
Jina         10M tokens

Some free tiers require account registration or a payment method. Check the upstream provider rules.

Parallel and You.com also offer separate free MCP Search endpoints. The providers in this plugin currently use their REST APIs and therefore still use API keys.

Provider order

Set the order in which providers are used:

Tavily → Firecrawl → Exa → Parallel → Brave

The first provider is the default.

Providers in the search chain can be reordered by dragging.

Removing a provider from the chain does not delete its configuration, so it can still be tested manually.

Fallback

The plugin tries the next provider when the current one has problems such as:

rate limit
timeout
network error
service error
quota exhausted

Example:

Tavily
   ↓ timeout
Firecrawl
   ↓
success

If an API key fails authentication and the provider has multiple keys, another available key is tried first.

Multiple API keys

Each provider can have multiple API keys:

Tavily
├── Key A
├── Key B
└── Key C

The plugin automatically selects an available key.

Keys can be separated by:

newlines
commas
spaces
semicolons

Full API keys are never returned to the browser. The Settings page only receives masked credential information.

Quota

Current quota support:

For supported providers, quota from multiple API keys is combined.

Example:

Key A: 950 / 1000
Key B: 982 / 1000

Pool: 1932 / 2000

Quota is refreshed in the background with a default 5-minute cache.

Brave quota is read from the X-RateLimit-* information returned by Search and the latest result is saved.

Quota information is only used for display and does not block Search.

Test Search

The Settings page can run a real search through the configured provider chain.

It shows:

• final provider
• total latency
• result count
• provider attempts
• success / timeout / rate limit / authentication failure
• search results

Test Search uses the same provider chain as normal agent searches.

Web Fetch

Providers with page-content support:

Tavily
Exa
Firecrawl
Parallel
Jina

A normal flow can be:

web_search
    ↓
URL
    ↓
web_fetch
    ↓
page content

Search and Fetch do not have to use the same provider.

For example:

Brave Search
    ↓
Parallel Fetch

Proxy

Supports:

HTTPS_PROXY
HTTP_PROXY
Windows system proxy

Local addresses bypass the proxy by default:

localhost
127.0.0.1
::1
*.local

NO_PROXY is also supported.

SearXNG

SearXNG does not require an API key.

Configure only the instance URL:

http://127.0.0.1:8080

It can be used alone:

SearXNG

or as part of the fallback chain:

Tavily → Exa → Brave → SearXNG

UI language

The Web Search page supports:

Follow system
中文
English

The language setting only affects this plugin page.

Security

• API keys are used only on the DSH Host
• full API keys are never returned to the browser
• logs do not contain full API keys
• requests do not pass through a server operated by this project
• no search usage telemetry is uploaded
• SearXNG can be used as a fully self-hosted search option

Development

Install:

npm install

Test:

npm test

Type-check:

npx tsc -p tsconfig.json --noEmit
npx tsc -p tsconfig.client.json --noEmit

Build:

npm run build

Provider adapters are in:

src/host/providers/

See CONTRIBUTING.md for more information.

Update still showing old code?

If the plugin still behaves like an older version after updating and restarting:

cd ~/.dsh/profiles/web
pnpm install

For local development, file: may use a copied snapshot.

Using link: is usually more convenient.
