bub vs MCP-Generator

Q: Which is better, bub or MCP-Generator?

By GitHub stars, bub has more community adoption, but the best choice depends on your specific use case.

bub: Bub is a small Python agent runtime built on agents.md and Agent Skills, where every stage of a turn is a pluggy hook that plugins can override. Context is rebuilt from append-only tape records, and the same pipeline serves the CLI, Telegram and custom channels.; MCP-Generator: MCP-Generator is a command-line tool that transforms OpenAPI v3 specifications into full-fledged MCP (Multi-Agent Communication Protocol) servers. It supports TypeScript, Python, and Go, generating typed models, API clients, and preserving custom code across regenerations.

MCP-Generator

Features

bub

01Turn pipeline where every stage, from resolve_session to dispatch_outbound, is a replaceable hook

02Tape context rebuilt from append-only records, easy to inspect and replay

03One runtime across CLI chat, one-shot runs and a Telegram gateway

04Agent Skills discovery and plugin packaging through Python entry points

MCP-Generator

01Generates MCP servers from OpenAPI v3 specifications in TypeScript, Python, or Go.

02Maps API routes to typed MCP tools with input parameters, example responses, and complex schema support (oneOf/anyOf).

03Supports incremental code preservation, allowing custom logic to be retained during code regeneration.

04Provides a validation command to check OpenAPI specs for issues like name collisions, missing examples, and unsupported schemas.

05Option to generate handlers that call the real API over HTTP (HTTP client mode) instead of returning example stubs.

Use Cases

bub

↳Running an agent in a group chat shared by several people

↳Building a custom agent by overriding only the prompt or model stage

↳Experimenting with replayable, auditable agent context

MCP-Generator

↳Rapidly scaffold an MCP server project for a new API based on its OpenAPI definition.

↳Integrate existing APIs into multi-agent systems by automatically exposing them as typed MCP tools.

↳Automate the generation of API server code, client code, and data models for multiple programming languages (TypeScript, Python, Go).

↳Maintain up-to-date server implementations by regenerating code when the OpenAPI specification evolves, while preserving custom business logic.

↳Validate OpenAPI specifications for correctness and adherence to best practices during the API design and development process.
