Web Search

Use native web search and fetch in Claude Code, Codex, and ChatGPT while connected through FireConnect.

Web search is built into Fireworks. When Claude Code calls its native WebSearch tool, Fireworks runs the search server-side and returns the results, with no MCP server or search service to set up. Connect the harness through Coding Harnesses.

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

Web search pricing will be published soon.

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

FireConnect versions before 0.9.7 installed the fireworks-websearch MCP for Claude Code. That MCP is no longer available, because Fireworks now handles Claude Code’s native search tools server-side.

fireconnect upgrade

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