Create Charts from Your AI Assistant

Connect Claude, ChatGPT, Cursor, or any MCP-capable assistant to CleanChart. Paste messy data into your chat and get a publication-ready chart back — your assistant cleans the data, picks the config, and renders it for you.

How It Works

1. Hand over your data

Paste a table, CSV snippet, or numbers into the conversation and ask for a chart.

2. The assistant fixes it

CleanChart reports issues like mixed date formats in a machine-readable way, and your assistant corrects them automatically — no manual cleanup.

3. Chart in the chat

The rendered PNG appears directly in the conversation. Your data is processed in memory and never stored. Only if you ask for a download link is the chart image (never your data) kept for 24 hours, then deleted.

Connect Your Client

Server URL: https://www.cleanchart.app/api/mcp

Claude (claude.ai & Desktop)

Settings → Connectors → Add custom connector, then paste the URL:

https://www.cleanchart.app/api/mcp

Claude Code

One command in your terminal (the --header line is optional and only needed with an API key):

claude mcp add --transport http cleanchart https://www.cleanchart.app/api/mcp \
  --header "Authorization: Bearer cc_your_key_here"

Cursor / VS Code

Add to your MCP settings (mcp.json); the headers line is optional and only needed with an API key:

{
  "mcpServers": {
    "cleanchart": {
      "url": "https://www.cleanchart.app/api/mcp",
      "headers": { "Authorization": "Bearer cc_your_key_here" }
    }
  }
}

Other MCP clients

Any client that supports remote MCP servers (Streamable HTTP) works — point it at:

Available Tools

Tool	What it does
list_chart_types	All 29 chart types with their default configurations
validate_chart_config	Check a chart config before rendering — instant feedback on what is missing
detect_data_issues	Find duplicates, missing values, mixed date formats, and type problems in your data
apply_data_fixes	Clean the data: deduplicate, standardize dates, fix types, fill gaps
generate_chart	Render the chart and get it back as a PNG image, right in the chat — optionally with a 24h download link
get_entitlements	Show your current tier (free, day pass, or subscription)
create_checkout	Get a payment link for a single clean chart, a 24h pass, or a subscription
claim_chart	Redeem a paid single-chart purchase — clean, full-resolution PNG in the chat

Free to try — no account needed

Without an API key, charts use the free tier: watermarked, reduced resolution. For a one-off clean chart, ask your assistant to create a checkout — pay in the browser, and the clean chart arrives right in the chat.

API keys — clean charts by default

With a subscription or 24h pass, create an API key in your dashboard and add it to your client's MCP config as a header. Every chart is then watermark-free and full resolution.

Header name: Authorization — header value: Bearer cc_your_key_here (the word "Bearer", a space, then the key).
If your client offers a list of auth types, pick Bearer token and paste just the cc_... key. Options like api_key or X-API-Key will not work — the server only reads the Authorization header.
In claude.ai / Claude Desktop, open the connector's advanced/authentication settings and add the key there (pick the Authorization / Bearer option). Also works in Claude Code, Cursor, VS Code, and any client that lets you set request headers.
