FlowchartAI MCP
The FlowchartAI MCP server enables AI assistants to create, edit, save, and export flowcharts directly within the FlowchartAI platform. It supports OAuth and API key authentication, allowing agents to generate diagrams from natural language, revise existing files, manage versions, and export results in formats like draw.io XML or JSON. The server handles task receipts and credit usage, ensuring secure and controlled access to diagramming tools without requiring local server installation.

}Ground your agent in cited data
FlowchartAI MCP gives your agent tools. Koskamo gives it reviewed, cited facts to check its answers against. Add it as a second MCP server; public reads need no API key.
