MCP server

Let AI assistants make the chart.

The RenderChart MCP server lets Claude, ChatGPT, Claude Code and Cursor turn your numbers into a chart URL, so the reply shows the chart as an image. Included on Starter and Pro.

Choose Starter Read the MCP docs

Connect it in three steps.

The server URL is the same for every assistant.

https://app.renderchart.com/mcp

Open it in a browser while signed in to see your own setup page, with your tokens and authorisations.

In Claude, open Customize, then Connectors.
Choose + and then Add custom connector. Paste the server URL and choose Add.
Claude sends you to RenderChart to sign in and approve. Works in Claude.ai and Claude Desktop.

Create a personal MCP token on the MCP page in the app. It is shown once.

Add the server from your terminal:

claude mcp add --transport http renderchart --scope user https://app.renderchart.com/mcp \
  --header "Authorization: Bearer rc_mcp_live_YOUR_TOKEN"

Leave out --scope user to add it to the current project only.

Create a personal MCP token on the MCP page in the app.

Add this to ~/.cursor/mcp.json for every project, or .cursor/mcp.json for one:

{
  "mcpServers": {
    "renderchart": {
      "url": "https://app.renderchart.com/mcp",
      "headers": {
        "Authorization": "Bearer rc_mcp_live_YOUR_TOKEN"
      }
    }
  }
}

Cursor picks the server up on its next start.

What you get back.

The assistant writes a chart URL from the data in the conversation and puts the image in its reply. You can copy the URL and use it anywhere else.

Chart the support survey: 46 very satisfied, 31 satisfied, 15 neutral, 8 unsatisfied.

AssistantHere it is as a pie chart. Three in four people are satisfied or very satisfied. Pie chart of survey answers: 46 very satisfied, 31 satisfied, 15 neutral, 8 unsatisfied

Illustration of a reply. The chart is real; the conversation is an example.

Your account: Charts are made with your key, so they count like any other render. Repeated charts come from cache.
Plain URLs: The result is an ordinary chart URL. Paste it into an email, a sheet or a README and it shows the same chart.
Short URLs: Ask for a short URL to hide your key and data. On Pro the assistant can update a short chart's data and the same URL shows the new chart.
Plans: MCP access comes with Starter and Pro, and needs a verified email address. Free accounts can still paste chart URLs into any assistant by hand.
