ChartOne MCP renders themed charts for AI agents and returns them as an inline image plus a persistent hosted URL. It can run locally via MCP clients or through a hosted endpoint, with anonymous usage producing watermarked charts.
From the registry: Render themed charts as hosted URLs. Embed in markdown, emails, and Slack. Hosted MCP, zero setup.
Please install the `chartone` MCP server into my current AI client (that's you).
Required prerequisites (do these first if not already done):
- **Install Node.js and npx** — Required to run the MCP server via npx.
Optional prerequisites:
- Get a ChartOne API key — Optional. Sign up for a ChartOne account to get an API key for non-watermarked charts and extended URL lifetime. Without a key, anonymous mode works but returns watermarked charts. (https://chartone.dev)
Canonical MCP server config (stdio transport):
- command: `npx`
- args: ["-y","@chartone/mcp"]
- optional environment variables:
- `CHARTONE_API_KEY`: ChartOne API key. Optional; if omitted, the server runs in anonymous mode and returns watermarked charts. (example: `<your-chartone-api-key>`)
Note: The README also documents a hosted HTTP endpoint for cloud agents: POST <https://api.chartone.dev/mcp> with optional Authorization: Bearer <your-chartone-api-key>. Canonical local install uses stdio via npx as the simplest portable path.
Add this MCP server to my current client's config in the correct format for you. If you need secrets or credentials I haven't provided, ASK me — do not invent values or leave raw placeholders. After adding it, tell me how to verify the server is connected.CHARTONE_API_KEYrequiredAPI key used to authenticate requests and enable unwatermarked chart rendering.Make 3D games in Unity Engine with AI.
