MCP server that wraps the Dagster GraphQL API — manage runs, assets, schedules, sensors, and backfills from any MCP client
CleanChart is installed from its publisher's own source and answers where it runs, so this marketplace is not in the path of a single call. There is no address here to send one to, and a panel that pretended otherwise would be showing you an answer we made up. Install it and call it from your own client — the Installation tab has the entry for each one.
What it does
Clean messy tabular data and render publication-ready PNG charts from your AI assistant.
Quickstart
# 1 — add it to Claude Code
claude mcp add --scope user --transport http cleanchart-mcp https://www.cleanchart.app/api/mcp
# 2 — ask your agent for something these tools do
# list_chart_types, validate_chart_config, detect_data_issues and 5 more
CleanChart costs nothing on mcprush: there is no plan to choose here, no cap to set and nothing mcprush can bill you for.
Collected from a public index. Nobody has claimed this account, so nothing here was written by its author — claim it if it is yours.
Where are you running it?
Every route below installs the same thing and ends at the same approval screen. Nothing here runs on your machine and nothing runs on ours: this server answers at its publisher’s own address, and what you install is the connection straight to it.
This is a public server: it answers at its publisher’s own address and this marketplace is not in the path. Claude Code registers it in one command; --scope user makes it available in every project. The transport below is http, as the publisher's own manifest declares it.
claude mcp add --scope user --transport http cleanchart-mcp https://www.cleanchart.app/api/mcpReconnect, or start a new session, and the tools appear in the model’s tool list.
Nothing is required, but it can take Authorization header (Optional. "Bearer cc_..." API key from https://www.cleanchart.app/dashboard. Watermark-free output needs an active 24h pass or subscription. Omit for the free tier.) if you want to set it.
One config entry pointing straight at the publisher’s own address — this marketplace is not in the path, and nothing from this listing executes on your machine.
8 tools, with what each one reads, writes and reaches shown before you agree — the same list on every route above. Read the tool surface.
Tool surface
What the model actually sees. Descriptions are diffed on every release — see version history.
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.
No parameter schema on file.
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.
| Parameter | Type | Required | Notes |
|---|---|---|---|
| chartType | string | yes | Chart type id from list_chart_types |
| config | object | yes | Chart config object (start from the type's defaultConfig) |
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.
| Parameter | Type | Required | Notes |
|---|---|---|---|
| data | array | yes | Tabular data as an array of row objects, e.g. [{"Month":"2026-01","Sales":120}, ...]. All rows should share the same keys (column names). |
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
| Parameter | Type | Required | Notes |
|---|---|---|---|
| data | array | yes | Tabular data as an array of row objects, e.g. [{"Month":"2026-01","Sales":120}, ...]. All rows should share the same keys (column names). |
| fixOptions | object | yes | Fix options object, e.g. {"remove_duplicates":true,"date_standardization":true,"date_columns":["Date"]} |
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 hour

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.

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.

- Every tool — any call limit is its publisher’s, not ours
- No card, and mcprush charges nothing for it
- Runs at its publisher’s own address — this marketplace is not in the path
- Nothing to cap, because mcprush bills nothing
What counts against your monthly calls
| Tool | Unit | Calls used | Out of the allowance |
|---|
Nothing here is billable: mcprush charges nothing to install CleanChart or to call it, at any volume.
Two independent axes, because powerful and malicious are different questions. The grade is threat only. The capability level is blast radius, and it is never a penalty on the grade — it is priced as one subtract-only term in the score, where you can see it.
| Term | Level | What it prices | Points |
|---|---|---|---|
| capability-exposure | minimal | capability blast radius (minimal) — client exposure if the model is manipulated | −0 |
| coverage-honesty | manifest | inspection depth (manifest) — how much of the target the scan could see | −4 |
What the scan could actually read
A grade is only as meaningful as its coverage, so the scanner publishes its own depth before it publishes its result.
The scan read each tool’s name, description, input schema and annotations exactly as the server listed them the last time it answered us; no code was reviewed. We ask the server again about once a month, and a list that changed is graded again.
The implementation source was not read — this reflects the declared tool metadata only.
Capability — what it could do if the model were manipulated
Tags derived from each tool’s schema and the implementation, not from what the tool calls itself. minimal is the level these add up to.
| Tool | Capability tags | Why the tag was assigned |
|---|---|---|
| list_chart_types | no tags | |
| validate_chart_config | no tags | |
| detect_data_issues | no tags | |
| apply_data_fixes | no tags | |
| generate_chart | no tags | |
| get_entitlements | no tags | |
| create_checkout | no tags | |
| claim_chart | no tags |
Toxic-flow graph
The lethal trifecta, checked as a graph rather than as a checklist: untrusted input, a sensitive source and an external sink have to meet before there is a path worth worrying about.
The public result for this release does not print the flow graph, so there is nothing to show here. That is not the same as "no paths were found": what the scan did read is above, under coverage.
Supply chain and provenance
This is the first scan of this surface here, so there is nothing yet to compare it against.
Every result on this tab comes from one deterministic pass over the published package — offline, rule by rule, and auditable line by line above. Same methodology version, same bytes, same score.
Release history
This is an address its publisher runs: which release it serves is theirs to choose, so there is nothing here to pin. The history below is for reading; the current release on file is 1.0.0.
No release note was published with this version.
One review per account, from a signed-in account that does not publish this listing. Nothing else is asked — you can say what you think before you install it. Publishers can reply once per review, and a review can be edited or deleted by whoever wrote it.
Any signed-in account that does not publish CleanChart can review it, once — before installing it or after. A review from an account that has installed it is marked as one.
Nobody has reviewed this listing. The rating on the card is the mean of the reviews written here and nothing else, so there is no rating until somebody writes the first — which takes a signed-in account that does not publish it, and nothing else.
