ZeroMCP FAQs

Question 1

Can I integrate ZeroMCP with existing web frameworks like Flask or FastAPI?

Accepted Answer

Yes, ZeroMCP is designed for flexible HTTP integration. It provides an async handler that processes JSON-RPC requests, allowing you to easily integrate it with any async-compatible Python web framework, such as Flask, FastAPI, or Starlette.

Question 2

What are the key advantages of ZeroMCP over official MCP SDKs?

Accepted Answer

ZeroMCP offers superior performance (up to 12x faster and less memory), comprehensive runtime sandboxing (network, credentials, filesystem controls), and a zero-dependency architecture (standard library only). Official SDKs often lack sandboxing and require more setup.

Question 3

Does ZeroMCP have any external dependencies?

Accepted Answer

No, ZeroMCP is built purely on Python's standard library. It requires Python 3.10+ but has zero external dependencies, making it lightweight and easy to deploy.

Question 4

What is ZeroMCP and how does it simplify server creation?

Accepted Answer

ZeroMCP allows you to instantly create high-performance, sandboxed MCP servers by simply dropping Python `.py` files into a folder. It features zero-config, file-based tool discovery, eliminating the need for complex server objects or decorators.

Question 5

How does ZeroMCP ensure the security of my tools?

Accepted Answer

ZeroMCP implements robust runtime sandboxing, including per-tool network allowlists, credential isolation (tools access secrets via `ctx.credentials` not `os.environ`), and granular filesystem controls (requiring explicit `fs: 'read'` or `fs: 'write'` declarations).
