What is the Exec Sandbox MCP Server?

Single exec tool running caller Python in a network-isolated locked-down sandbox.

What you get

Public OSS MCP server (Go, MIT) exposing a single powerful tool — exec — that runs caller-supplied Python code in a network-isolated, locked-down sandbox and returns stdout / stderr / exit_code. It is the "code-execution mode" building block: instead of flooding an agent's context with hundreds of tool schemas, the agent writes code that orchestrates the work.
