Summary
Turns hex color codes into human-readable names using established color naming conventions. Useful when you're working with design systems, need to document color palettes, or want to communicate colors in a more natural way than #3B82F6. Part of the Pipeworx gateway ecosystem, which means you can either connect to it standalone or access it through their unified gateway alongside 776+ other data sources. The ask_pipeworx interface lets you query in plain English rather than calling tools directly. Good fit if you're building design tools, color pickers, or accessibility checkers where color communication matters.

Color Pizza MCP — names hex colors using human-friendly color-name lists.
Part of Pipeworx — an MCP gateway connecting AI agents to 1476+ live data sources.
Tools
| Tool | Description |
|---|---|
name_colors | Find the nearest human-friendly color name for one or more hex colors. Pass hex codes (with or without leading #), comma-separated for several at once. Returns the closest named color for each input, with its canonical hex, RGB, and perceptual distance. Optionally pick a naming list (e.g. "wikipedia", "ntc", "x11", "html", "japaneseTraditional", "leCorbusier", "bestOf"); defaults to "default". Use list_palettes to see all available lists. |
search_color_names | Search named colors whose name contains a substring (e.g. "blue", "rose", "teal"). Returns matching color names with their hex codes. Optionally restrict to a specific naming list (see list_palettes). |
list_palettes | List all available color-name lists (palettes) with their titles, descriptions, color counts, and licenses. Use this to discover valid values for the "list" argument of name_colors and search_color_names. |
Quick Start
Add to your MCP client (Claude Desktop, Cursor, Windsurf, etc.):
{
"mcpServers": {
"color-pizza": {
"url": "https://gateway.pipeworx.io/color-pizza/mcp"
}
}
}
What this endpoint actually serves
tools/list at https://gateway.pipeworx.io/color-pizza/mcp returns the tools in the table
above plus the shared Pipeworx meta-tools — ask_pipeworx,
discover_tools, search_within, remember/recall and the rest of the
gateway-wide set. So the tool count you see is larger than this table: a
single-pack endpoint currently lists roughly 30 shared tools alongside the
pack's own. The connection's initialize response states its exact scope, and
is the authoritative answer for a given day.
This is deliberate, not multiplexing by accident. The meta-tools are what let a
scoped connection answer a question this pack does not cover — via
ask_pipeworx, which routes across the whole catalog — without you adding a
second MCP server. There is currently no way to mount a pack endpoint without
them; if the extra schemas cost you more context than the routing is worth,
connect to the full gateway once rather than to several pack endpoints.
Or connect to the full Pipeworx gateway to get every pack's tools listed directly, instead of just this one's:
{
"mcpServers": {
"pipeworx": {
"url": "https://gateway.pipeworx.io/mcp"
}
}
}
Both URLs reach the same gateway and the same 1476+ data sources. The
only difference is which pack's tools are listed directly; ask_pipeworx
reaches all of them from either one.
Using with ask_pipeworx
Instead of calling tools directly, you can ask questions in plain English — this works on the pack endpoint above as well as on the full gateway:
ask_pipeworx({ question: "your question about Color Pizza data" })
The gateway picks the right tool and fills the arguments automatically.
