Spec Driven Development
MCP Server that facilitates spec-driven development workflows, not just Vibe Coding.
Description from the maker (original English)
Create, inspect, manage, and render charts and data visualizations as SVG/PNG or interactive embeds.
These three are never merged into one score: opinions, measurements and popularity are different things.

Tool names and descriptions exactly as the server reported them on Nov 6, 2026. The maker wrote them, not us; we show them as plain text.
render_chartUse this when the user wants to preview or generate a chart. Validate each generated or changed chart input once before rendering, saving, or updating. Do not revalidate unchanged input; a successful render preflights it for later saves or updates. Errors block; warnings require
save_chartUse this when the user wants to permanently save and publish a Szum chart document. Validate each generated or changed chart input once before rendering, saving, or updating. Do not revalidate unchanged input; a successful render preflights it for later saves or updates. Errors b
list_chartsUse this when the user wants to find charts in their saved library. Returns paginated metadata and URLs, not chart documents; requires authentication. Draft-only editor charts have publishedAt null, hasDraft true, and sizeBytes 0 because sizeBytes measures only the stored publish
get_chartUse 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 document; requires authentication.
get_chart_documentUse this when the user identifies a saved chart by id and needs its complete published Szum document for inspection or reuse, or an earlier version's document from list_chart_versions. Does not return a newer editor draft; requires authentication.
list_chart_versionsUse this when the user wants to see a saved chart's earlier publications, find one to read with get_chart_document, or pick one to restore with restore_chart_version. Returns versions newest first with who published each, from where and what changed; requires authentication.
get_preview_stateUse 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.
update_chartUse this when the user wants to replace and publish a saved chart's document while keeping its id and URLs. Validate each generated or changed chart input once before rendering, saving, or updating. Do not revalidate unchanged input; a successful render preflights it for later sa
restore_chart_versionUse this when the user wants a saved chart to go back to an earlier version from list_chart_versions. Publishes that version's document again as a new version, keeping the chart's id and URLs, so the version it replaces stays restorable. Refuses charts with unpublished editor cha
rename_chartUse this when the user wants to change a saved chart's library title without changing its document, publication state, or public URLs; requires authentication.
delete_chartUse 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.
list_themesUse this when choosing a visual theme for a chart. Returns every built-in theme with guidance on where each works best and, when signed in, the workspace's shared themes.
validate_chartUse this when a chart request or document will be rendered, saved, or updated. Validate each generated or changed chart input once before rendering, saving, or updating. Do not revalidate unchanged input; a successful render preflights it for later saves or updates. Errors block;
list_chart_typesUse this when choosing a chart family. Returns every current chart type with its shared and family-specific fields.
get_examplesGet complete Szum documents for validation, rendering, or saving, with guidance on when to use each pattern. No filters returns one starter per chart type. Any filter searches the complete catalog; all supplied filters intersect. Most data is illustrative; the Vinyl waterfall cit
get_schemaUse this before authoring an unfamiliar field instead of probing validate_chart for errors. Returns the JSON Schema for the whole Szum document, covering config, data, presentation, size, and output, with every referenced definition included. Pass chart_type to keep only that fam

Compared with every active server in this category in the registry. Stars count only when the publisher owns the repo.
It passed 2 of 3 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.
The registry does not list a required key, though some servers ask you to sign in on first use.
It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.
