dsh-web-search-ext

Multi-backend web_search provider for the DeepSeek Harness web seam (ctx.web): Exa (REST with key, anonymous hosted MCP without) and Firecrawl (v2 search API) today, extensible to more backends (SearXNG, ...), with automatic failover when one backend rate-limits

AI Analysis

核心用途是扩展 DSH 的网页搜索能力。适合需要高可用搜索、在某一后端频次受限时能自动切换到其他搜索源（如 Exa 或 Firecrawl）的用户。
