Connect Zero-Configuration Exa Search to DeepSeek Harness with dsh-web-search-exa

The community plugin `dsh-web-search-exa` provides an Exa search provider for DeepSeek Harness's `ctx.web`: it uses the anonymous MCP of `mcp.exa.ai` without an API key, and will automatically switch to REST mode once `EXA_API_KEY` is configured. This article covers the directory page, verifies installation commands, configuration items, coexistence with official packages via GitHub and official documentation, as well as edge cases such as current limiting, no built-in setup UI, and process permissions.
