Moka
An open-source local MCP debugging tool that provides a visual playground for testing MCP servers and prompts. It supports one-click export of LangGraph code, runs locally with zero configuration, and operates entirely without dependence on third-party services.
Timeline (last 90 days)
Moka is an open-source local visual debugging tool for MCP and LangGraph developers, providing a purely local-running playground for testing MCP tools and prompts before coding
Moka provides a local chat interface for testing tool calls, streaming output, and underlying raw JSON-RPC traffic
Moka supports clicking the Export as code button to generate directly runnable LangGraph (Python) scripts after debugging the workflow in the visual interface
Moka supports pointing to an existing LangGraph agent via the AG-UI protocol, serving as a debugging interface for that agent
Moka can be launched with a single command npx @mokalabs/sandbox, emphasizing zero-configuration local operation
Moka has been open-sourced on GitHub, with the repository address at github.com/mokahq/mokalabs
Moka has chosen LangGraph as the sole code export target
Moka runs entirely locally with data that does not need to be uploaded to any third-party service, providing privacy and security advantages for developers handling sensitive tools or internal APIs
As a newly released open-source project still in its early stages, Moka's MCP server compatibility, complexity coverage of exported code, and long-term maintenance remain to be validated by the community
