dsh-all-search: A single API key for DeepSeek Harness to aggregate multi-backend search

dsh-all-search is an MIT-licensed DSH (DeepSeek Harness) plugin maintained by RealAlexandreAI that registers a network search provider named "anysearch" for DSH. It aggregates four backends—exa, tavily, firecrawl, and context7—through a single AnySearch MCP gateway using a single API key, eliminating the need to apply for credentials individually.
