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 (25%), doing the product's job (25%), definitions (20%), context (10%), use (10%) and how readily a client connects (10%). 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 →
assess_tattoo_ideaUse when the user describes a specific tattoo idea and asks whether it will hold up at a given size and body placement. Compares the design with published minimum sizes for its kind of design and returns the placement's fade, sun…
check_line_spacingUse when the user gives a line width and the gap between two lines or letters in millimetres and asks whether the gap will stay open as the tattoo ages. Applies the published rule of thumb that a line widens by about 0.1 mm per decade…
get_tattoo_size_chartUse when the user asks how big or how small a kind of tattoo can be, or what fits at a given size. Returns the smallest and better size for eight kinds of design (letters by height, other designs by longest side), real-world size…
compare_tattoo_placementsUse when the user asks how body areas compare for pain, fading, sun, friction, stretch or curvature, or which areas hold ink longest. Returns the ten common areas (or the ones requested), ordered by fade by default. Estimates are coarse…
get_pre_booking_checklistUse when the user asks how to decide whether they are ready to book a tattoo, what to ask an artist, or what red flags to watch for in a consultation. Returns a short ordered checklist, the one question to ask when an artist pushes back…
How to connect
Add the server to your MCP client config. Claude Desktop, Cursor and most other clients read this shape:
{
"mcpServers": {
"check-tattoo": {
"type": "http",
"url": "https://mcp.check.tattoo/mcp"
}
}
}Add it
Claude Code, in a terminal
claude mcp add --transport http check https://mcp.check.tattoo/mcpclaude.ai, ChatGPT and other clients: add https://mcp.check.tattoo/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.
