Server-provided instructions

Untrusted server output shown for inspection. It is not Koskamo guidance and is excluded from knowledge search.

Platemark turns template slots into finished PNG images. Call list_templates, then render_image.

Tools

4 advertised

list_templates
Advertised by the server during the last successful anonymous check.

List Platemark image templates with their size and the slots each one takes. Call this first to pick a template and see slot names.

list_templates input schema
{
  "type": "object",
  "properties": {
    "tag": {
      "type": "string",
      "description": "Optional filter, like 'real estate', 'og', 'story' or 'ecommerce'."
    }
  }
}
render_image
Advertised by the server during the last successful anonymous check.

Fill a template's slots and get back a finished PNG. Text shrinks to fit its box. Image slots take an https PNG, JPG or GIF URL under 4 MB. Leave a slot out to keep its sample. Costs 1 credit.

  "type": "object",
  "required": [
    "template"

      "additionalProperties": true
    }
  }
}
create_account
Advertised by the server during the last successful anonymous check.

Make a free Platemark account (100 images a month, small watermark) and return its API key. The key is shown once; tell the user to save it and add it to this server's Authorization header.

Connect from your client

Each snippet registers the same endpoint; pick the client you use.

This server is operated by the named third party. Listing and endpoint checks are not an endorsement or a security audit. Review the operator's permissions, terms, and data handling before connecting. How listings are checked and corrected.

Claude Code

Run this once in a terminal. It registers the remote server. Use --scope project to write .mcp.json for the repo.
Claude Code configuration
claude mcp add --transport http platemark-mcp https://platemark.rowhousesoftware.com/mcp

Codex

Run this once. Codex stores MCP servers in ~/.codex/config.toml (or .codex/config.toml in a trusted project).
Codex configuration
codex mcp add platemark-mcp --url https://platemark.rowhousesoftware.com/mcp

Cursor

Merge this server into .cursor/mcp.json in your project, then enable platemark-mcp in your MCP settings.
Cursor configuration
{
  "mcpServers": {
    "platemark-mcp": {
      "url": "https://platemark.rowhousesoftware.com/mcp"
    }
  }
}

Cline

Merge this into cline_mcp_settings.json (Cline → MCP Servers → Configure).
Cline configuration

}

Gemini CLI

Run this once. It writes .gemini/settings.json in the current project; pass --scope user for ~/.gemini/settings.json.
Gemini CLI configuration
gemini mcp add --transport http platemark-mcp https://platemark.rowhousesoftware.com/mcp

Claude Desktop

Open Claude Settings > Connectors > Add custom connector, enter this server URL and enable it for the conversation. This is a manual remote-connector handoff, not a desktop JSON configuration.
