MCPFlo v0.0.6
Pre-release
The first public release of MCPFlo — a visual testing tool for MCP (Model Context Protocol) servers. Connect to any MCP server, browse what it exposes, and inspect its capabilities. Think Postman, but for MCP.
⚠️ Early development. MCPFlo is brand new and moving fast. Connecting and browsing work today; tool calling and visual chains are next on the roadmap. Expect rapid change.
What's in this release
- Connect over stdio — spawn a local MCP server from a command and args (e.g.
npx -y @modelcontextprotocol/server-memory) - Connect over Streamable HTTP — point MCPFlo at a remote MCP endpoint
- Browse capabilities — every tool, resource, and prompt the server exposes, discovered automatically on connect and shown in a navigable tree
