Craftery MCP server

Which servers in the official MCP registry are Craftery's own, whether they answer, and what they offer. A program checked each of these, nobody copied them from a product page.

Whose server it is
  • Registry namedev.craftery/toolsverified in the MCP registry

The registry name sits under craftery.dev. The registry only lets a publisher use that namespace after proving control of the domain through DNS or HTTP.

On 2026-10-21 the server answered initialize and tools/list without a sign-in. First answer in 43 ms.

  • Whether its tools do the product's job has not been judged yet.

Said by rules from the measurements above. The likely first call is a model's pick from the tool list; read its description before relying on it.

Worth a look

None of the five warning signs in these definitions.

A program checks the server once a day: initialize and tools/list, no model. Tokens are the definitions' length at about four characters a token. The grade averages six checks of every tool's name, description, schema and annotations; it says how well the tools are described, not whether they work. The score weighs what was measured and nothing else: answering (30%), doing the product's job (25%), definitions (20%), context (10%) and use (15%). A part that was not measured is left out, and a hidden instruction caps the score at 40. The state of vendors' MCP servers: method and numbers →

  • convert_color

    Converts a color into code for 12 formats: HEX, HEX8, rgba(), hsla(), closest CSS named color, closest Tailwind class, SwiftUI Color, UIColor, Jetpack Compose, Android XML, Flutter, and React Native. Applies each platform's alpha byte…

  • check_contrast

    Computes the exact WCAG 2.1 contrast ratio between a foreground and background color (relative-luminance formula) and reports AA/AAA pass-fail for normal text (4.5 / 7), large text (3 / 4.5), and UI components (3).

  • swiftui_color

    Generates every SwiftUI Color initializer for a color: Color(red:green:blue:), opacity variant, Color(.sRGB), Color(.displayP3), HSB, hex-extension call, #colorLiteral, UIColor/NSColor bridges — plus a reusable `extension Color` snippet…

  • generate_uuid

    Generates cryptographically random UUIDs: v4 (random), v7 (RFC 9562 time-ordered; batches stay strictly ordered), or NIL. Supports uppercase, hyphen-less, and braced formatting. 1–100 per call.

  • hash_text

    Computes MD5, SHA-1, SHA-256, SHA-384, and SHA-512 digests of a UTF-8 string, or HMAC variants when a key is given (HMAC-MD5 unsupported). Stateless; input is not stored.

  • convert_timestamp

    Converts between Unix epoch timestamps and human-readable dates. Accepts epoch seconds / milliseconds / microseconds (auto-detected by magnitude), ISO 8601 / RFC 2822 strings, or "now". Returns seconds, millis, micros, ISO 8601 UTC, RFC…

How to connect

Add the server to your MCP client config. Claude Desktop, Cursor and most other clients read this shape:

{
  "mcpServers": {
    "tools": {
      "type": "http",
      "url": "https://craftery.dev/mcp"
    }
  }
}

Add it

Claude Code, in a terminal

claude mcp add --transport http craftery https://craftery.dev/mcp

Add to CursorAdd to VS Code

claude.ai, ChatGPT and other clients: add https://craftery.dev/mcp as a custom connector in the settings.

Each line is something a program found when it went looking: the registry entry, the server's own answer, a spec that parses. A missing line means we did not find it, not that it does not exist.
