Code mode for Replicate's MCP server
Your browser does not support the video tag.
Replicate’s local MCP server now supports an experimental “code mode” that allows language models to write and execute TypeScript code directly in a sandboxed environment.
Instead of exposing individual API operations as separate tools, Code mode provides two tools: one for searching SDK documentation, and another for executing TypeScript code using the Replicate SDK within a Deno sandbox. The model uses a built-in docs search tool to learn how to write code against the SDK. This approach is more efficient for complex workflows that involve multiple API calls, as it reduces context window usage and allows the model to write custom logic that calls multiple methods and returns only the final results.
To use code mode, start the local MCP server with the --code-mode flag:
Copy
npx -y replicate-mcp@alpha --tools=code
Here’s how to add the local Replicate MCP server in code mode as a tool in Claude Code:
Copy
claude mcp add "replicate-code-mode" --scope user --transport stdio -- npx -y replicate-mcp@alpha --tools=code
Code mode is currently experimental and subject to change. It requires Node.js and Deno to be installed locally. Remote cloud sandboxing support is planned but not yet available.
To get started with Code mode, see the Code mode documentation or visit the demo GitHub repo.
