}Troubleshooting & Common ErrorsFAQ
Common connection errors and verified fixes for Agent Web Search
Getting 'connection closed' or exit code 1 in Cursor / Claude Code for Agent Web Search?
Usually caused by missing runtime paths or IDE environment inheritance. Fix steps: 1. Verify Node.js 18+ (npx) or Python 3.10+ (uvx) is installed; 2. Run 'which npx' or 'which uvx' in terminal, and replace 'command' with absolute path; 3. Reload or restart the client window after modifying config.
# Check binary path in terminal: which npx node -v
Getting 'spawn npx ENOENT' or 'command not found'?
The editor background process does not inherit your full terminal PATH. Solution: Globally install the package, or set the absolute binary path (e.g. C:\Program Files\nodejs\npx.cmd on Windows, or /usr/local/bin/npx on macOS).
Missing required environment variable or authentication failure?
Agent Web Search requires environment variables (AGENT_WEB_SEARCH_PROVIDERS、ARK_API_KEY、GEMINI_API_KEY、XAI_API_KEY、DEEPSEEK_API_KEY、AGENT_WEB_SEARCH_RESPONSES_API_KEY、AGENT_WEB_SEARCH_RESPONSES_BASE_URL、AGENT_WEB_SEARCH_MESSAGES_API_KEY、AGENT_WEB_SEARCH_MESSAGES_BASE_URL、TAVILY_API_KEY、BRAVE_SEARCH_API_KEY、PERPLEXITY_API_KEY、YDC_API_KEY、EXA_API_KEY、PARALLEL_API_KEY、ZHIPU_WEB_SEARCH_API_KEY、ZHIPU_CHAT_SEARCH_API_KEY). Ensure you have added valid keys under the 'env' object in your config file without trailing whitespace.
