Unmerge MCP server

Which MCP servers are Unmerge's own, from the official registry and from asking its own domain, 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 nameapp.unmerge/unmergeverified in the MCP registry

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

On 2026-10-29 the server answered initialize and tools/list without a sign-in. First answer in 112 ms.

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

Once connected

  • For "split a flat poster into named transparent layers", the likely first call is split_into_layers.

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.

Each of the product's use cases, put to Jev against this server's tool list: can an agent do it with these tools?

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 →

  • split_into_layers

    Split a flat image (PNG, JPG or WebP) into named transparent layers, with the hidden parts behind objects filled in. Costs 1 credit per layer returned (at most 17); the account needs at least 5 credits to start. Pass the image as a public…

  • get_layers

    Status of a split. When ready, returns every layer with its name, position and a PNG download URL valid for one hour. Free.

  • unlock_layers

    For a split with status needs_credits: pay the extra credits owed (shown as credits.owed) so the layer files become available. Charges once even if called again.

  • get_credits

    Credits available on this Unmerge account. One credit is one layer returned.

How to connect

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

{
  "mcpServers": {
    "unmerge": {
      "type": "http",
      "url": "https://unmerge.app/mcp"
    }
  }
}

Add it

Claude Code, in a terminal

claude mcp add --transport http unmerge https://unmerge.app/mcp

Add to CursorAdd to VS Code

claude.ai, ChatGPT and other clients: add https://unmerge.app/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.
