mcp-bash-framework is a Bash-only framework for creating Model Context Protocol servers without extra runtimes. If your automation already lives in shell scripts, this lets you expose it to MCP clients with almost no setup. Zero dependencies, cross-platform, protocol-compliant, and includes a small CLI, scaffolding tools, resource providers, progress streaming, and example projects to get started quickly.

This was a side project that gradually turned into a framework. The goal was to expose existing shell scripts to MCP clients without building a whole new stack. Along the way it ended up becoming a fairly complete implementation of the MCP spec for the stdio transport. It’s still early, so I’m interested in how others use it and where the rough edges are.
