Is cleanchart live?

Yes — it answered the hub's last check (checked 1h ago). It answered 100% of checks over the last 30 days.

Is cleanchart free to use?

Yes — the hub reached it with no key and no payment.

What tools does cleanchart have?

8 tools: apply_data_fixes, validate_chart_config, detect_data_issues, generate_chart, create_checkout, claim_chart, list_chart_types, get_entitlements.

Is cleanchart safe to connect?

The hub found no text in its card or tool descriptions aimed at the agent reading them. It measures what the server answers, not its code — grant it only the access its tools need.

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.

• list_chart_types open 1h ago

  List all chart types CleanChart can render, each with its default config object. Use a default config as the starting point, override what you need (title, xColumn, yColumn, colors, ...), then call validate_chart_config before generate_chart.

• get_entitlements open 1h ago

  Show the caller's current CleanChart tier. Anonymous callers are free tier (watermarked, reduced resolution). With an API key (Authorization: Bearer cc_..., created in the CleanChart dashboard) this reflects the account's subscription or 24h day pass.

• apply_data_fixes unknown never probed

  Clean tabular data with CleanChart's fix engine and get the cleaned rows back plus a change log. Options (all optional booleans unless noted): remove_duplicates, remove_empty_rows, remove_empty_columns, trim_whitespace, replace_invalid_values (turn N/A/-/? into null), nullify_missing, convert_types, missing_strategy ('fill_smart' fills gaps with column mean or 'Unknown'), date_standardization with date_columns (string[], converts recognized date formats to YYYY-MM-DD), strip_numeric_formatting with format_columns (string[]), strip_coded_values with coded_columns (string[]).

• validate_chart_config unknown never probed

  Dry-run validation of a chart config for a given chart type. Returns valid:true or a list of human-readable problems to fix. Always call this before generate_chart — it is free and instant, while a failed render costs a rate-limited attempt.

• detect_data_issues unknown never probed

  Analyze tabular data for quality issues before charting: duplicates, missing values, whitespace, invalid tokens (N/A, -, ?), type mismatches, outliers, inconsistent date formats, and per-column inferred types. Returns a report whose findings map directly to apply_data_fixes options.

• generate_chart unknown never probed

  Render a publication-ready chart from tabular data and return it as a PNG image. By default the image is only delivered inline and never stored — in chat UIs the user can save it straight from the conversation. If the user needs a downloadable file (e.g. your client cannot save inline images), pass returnUrl:true: the response then also includes chartUrl, a direct link to the PNG valid for 24 hours — surface it to the user. Without an API key the free tier applies: watermark and reduced resolution — mention the upgrade info from the response to the user if they want a clean export (create_checkout provides a payment link). With a CleanChart API key (Authorization: Bearer cc_...) and an active subscription or 24h day pass, output is clean and full resolution. Call validate_chart_config first; large datasets are sampled automatically.

• create_checkout unknown never probed

  Create a payment link the USER must open in their browser — never call this without the user explicitly asking to purchase. kind 'single_chart' (pass the exact data, chartType, and config to be rendered; after payment call claim_chart to receive the clean chart), 'day_pass' (24h unlimited clean exports), or 'subscription' (monthly unlimited). day_pass and subscription are account-based: after payment CleanChart emails a sign-in link, and an API key from the dashboard unlocks clean renders over MCP.

• claim_chart unknown never probed

  Redeem a paid single-chart purchase (from create_checkout with kind 'single_chart') and receive the clean, full-resolution PNG. Call this after the user confirms payment. Returns payment_pending while the checkout is unpaid — wait for the user, do not poll in a loop. By default the image is only delivered inline and never stored; pass returnUrl:true if the user needs a downloadable file — the response then also includes chartUrl, a direct link to the PNG valid for 24 hours — surface it to the user.
