Set SOURCEWEAVE_SEARCH_SEARXNG_BASE_URL, SOURCEWEAVE_SEARCH_CRAWL4AI_BASE_URL, SOURCEWEAVE_SEARCH_CACHE_REDIS_URL before connecting.

Claude Code

claude mcp add mrnaqa-sourceweave-web-search -- uvx sourceweave-web-search

Claude Desktop / Cursor / VS Code - add to config

{
  "mcpServers": {
    "mrnaqa-sourceweave-web-search": {
      "command": "uvx",
      "args": [
        "sourceweave-web-search"
