Charts by Szum is an MCP server with 13 tools an agent can call, among them delete_chart, get_chart, get_chart_config. It answers at https://szum.io/mcp over streamable HTTP, and it listed its tools to an anonymous client, so no sign-in was needed for that. Our probes reached it 6 of 6 times since 11 September 2026; the last check, on 24 October 2026, succeeded.
Create, inspect, manage, and render charts and data visualizations as SVG/PNG or interactive embeds.
Description as the publisher wrote it.
| Tool | What it does |
|---|---|
delete_chart | Use this when the user explicitly wants to permanently delete one saved chart. Deletion cannot be undone, and retrying an already completed deletion succeeds; requires authentication. Inputs: id |
get_chart | Use this when the user identifies a saved chart by id and wants to view it or retrieve its metadata and URLs. Displays the published chart when available and does not return its config; requires authentication. Inputs: id |
get_chart_config | Use this when the user identifies a saved chart by id and needs its complete published Szum config for inspection or reuse. Does not return a newer editor draft; requires authentication. Inputs: id |
get_examples | Use this when the model needs current, ready-to-use Szum chart configs or preferred semantic patterns. Optionally filters examples by mark type. Inputs: mark_type |
get_preview_state | Use this when the Szum chart App needs to restore a rendered preview as its current transient or saved view. It is read-only, owner-scoped when authenticated, and hidden from the model. Inputs: previewId |
list_charts | Use this when the user wants to find charts in their saved library. Returns paginated metadata and URLs, not chart configs; requires authentication. Draft-only editor charts have publishedAt null, hasDraft true, and sizeBytes 0 because size Inputs: source, sort, q, cursor, limit |

render_chart | Use this when the user wants to preview or generate a chart. Validate each generated or changed config once before rendering, saving, or updating. Do not revalidate unchanged input; a successful render preflights it for later saves or updat Inputs: acknowledgeWarnings, config |

Yes. It is published by szum.io and served from szum.io, the vendor's own domain: https://szum.io/mcp.

Put the server under mcpServers in ~/.cursor/mcp.json with the URL https://szum.io/mcp. The exact JSON is above, with the same setup for Claude Code, Claude Desktop, VS Code, Windsurf, Zed, Gemini CLI and the rest.
It listed its tools to an anonymous client, so reading the tool list needs no key. Individual tools can still ask for credentials in their own inputs.

First indexed 10 September 2026. The tools are exactly what the server returned; nothing on this page
is inferred from its name. Ranking in Neuronto search is never for sale.
