FAQPage Schema
How do I package an MCP server for Claude Desktop deployment?▼

To package an MCP server for Claude Desktop, you initialize a manifest, configure server tools, and validate the bundle to generate a distributable .mcpb file. This process supports both Node.js and Python MCP servers through a manifest-driven configuration.

What is an MCP bundle and when do I need it for Claude Desktop?▼

An MCP bundle (.mcpb) is a packaged archive containing your MCP server configuration and tools required for Claude Desktop. You need it to distribute and deploy local MCP servers in restricted environments, ensuring deterministic setup and compatibility.

Can I use Python MCP servers with the MCPB packaging workflow?▼

Yes, the MCPB packaging workflow fully supports Python MCP servers alongside Node.js. It uses a manifest-driven configuration to handle cross-language compatibility checks, ensuring both environments are correctly packaged and validated for distribution.

Does packaging an MCP bundle require signing for production distribution?▼

Signing is optional but recommended for production distribution. The packaging process enforces manifest correctness and compatibility checks, and allows you to optionally sign the .mcpb bundle to meet strict distribution requirements.

What's the best way to validate a manifest before packing an MCP bundle?▼

The best way to validate a manifest before packing is to use the built-in bundle validation step, which enforces manifest correctness and checks compatibility for your Node.js or Python MCP servers prior to generating the final .mcpb file.
