Web Search - Fireworks AI Docs

FireConnect preserves native web search when a supported harness routes through Fireworks. Connect the harness through Coding Harnesses. You do not need a separate search service or command.

Harness	Search behavior	Wire API
Claude Code	Native `WebSearch` and `WebFetch` remain available	Messages
Codex and ChatGPT	Native web search remains available	Responses
OpenCode, Pi, Cursor IDE, VS Code, Copilot, and DeepSeek Harness	FireConnect does not add web search	Not applicable

See native search in action

Native web search works with any Fireworks model. Both examples use FireRouter, but native web search works without a model router.

Upgrade from the retired MCP

Earlier FireConnect versions installed the fireworks-websearch MCP for Claude Code. That MCP is retired because the Fireworks Messages endpoint supports Claude Code’s native search tools.

fireconnect upgrade

The upgrade removes the retired MCP and legacy tool denials that FireConnect added. Restart Claude Code afterward.
