An r/ClaudeCode post asked about bridging Claude Code and Codex via MCP. Multi-agent setups need search APIs that work across agent runtimes. Five APIs ranked for orchestration compatibility.
Top Pick
Scavio's hosted MCP server with 11 named tools works across Claude Code, Codex (via MCP bridge), Cursor, VS Code, ChatGPT, and any MCP client.

Why Scavio Wins
- Tavily's LangChain integration is more mature and has broader community adoption. For LangChain-only agent setups, Tavily has more examples and documentation.
- The MCP advantage matters for multi-runtime orchestration: the same Scavio MCP server works in Claude Code, Cursor, VS Code, ChatGPT, and Codex (via MCP bridge). No per-runtime wrapper needed.
- For dual-agent setups (Claude Code + Codex), MCP is the bridge. Both agents can call the same Scavio MCP server, sharing the same search tool surface.
- Exa's semantic search is a different shape from keyword SERP. For research agents that need concept-similarity search, Exa is the better tool — pair with Scavio for keyword search.
- Multi-agent orchestration is still early. The practical setup: one search MCP (Scavio), one code MCP (Semble), one deep research delegator (Comet/Perplexity). Clear tool roles, no overlap.
