OpenAI Codex Adds Standalone Web Search Inside Code Mode and Richer MCP Tool Schemas

OpenAI Codex·medium signal

OpenAI's June 10 Codex changelog adds standalone web search callable directly from code mode — including from nested JavaScript tool calls — returning plaintext results, plus richer MCP tool schema support, smarter plugin-marketplace listings, and clearer 'doctor' reports. For agentic coding workflows this closes a gap where Codex previously couldn't fetch live external context mid-task. It mirrors the broader 2026 pattern of CLI coding agents folding web retrieval into the execution loop.
