Use Sumbloom MCP with Cline

Number puzzle API + MCP: solver-checked puzzles as JSON/SVG, daily puzzle. $5/mo; 50 free/day.

Remote MCP server (Streamable HTTP), nothing to install. Free: 50 free/day · Paid: $5/mo

Set it up

1. Click the MCP Servers icon in Cline's toolbar, open Configure and click Configure MCP Servers.
2. Add the server under "mcpServers" with "type": "streamableHttp" and save.
3. Check that the server is enabled and lists its tools.
4. Every tool here is read-only, so you can add tool names to "autoApprove" if you want Cline to run them without asking.

Add to cline_mcp_settings.json::

{
  "mcpServers": {
    "sumbloom": {
      "type": "streamableHttp",
      "url": "https://sumbloom.cybermaxtools.com/mcp?via=use-with-cline",
      "disabled": false,
      "autoApprove": []
    }
  }
}

With a paid key:

{
  "mcpServers": {
    "sumbloom": {
      "type": "streamableHttp",
      "url": "https://sumbloom.cybermaxtools.com/mcp?via=use-with-cline",
      "headers": {
        "x-api-key": "YOUR_KEY"
      },
      "disabled": false,
      "autoApprove": []
    }
  }
}

The settings file is local to your machine; do not paste it into a shared repository with the key in it.

Where it goes:

• cline_mcp_settings.json: in the IDE, click the MCP Servers icon › Configure › Configure MCP Servers
• CLI: ~/.cline/data/settings/cline_mcp_settings.json

Config format checked 2026-10-09 against Cline's MCP documentation.

Tools you get

Endpoint checked 2026-10-09: https://sumbloom.cybermaxtools.com/mcp answered an MCP initialize (protocol 2025-06-18) and tools/list with 1 tool, all marked read-only. No key was used and no tool was called.

Test the endpoint from a terminal

This lists the tools without a key and without calling any of them:

curl -s https://sumbloom.cybermaxtools.com/mcp \
  -H 'content-type: application/json' \
  -H 'accept: application/json, text/event-stream' \
  -d '{"jsonrpc":"2.0","id":1,"method":"tools/list"}'

If it does not work

• The field is "type" (not "transportType") and the approval list is "autoApprove".
• Set "type": "streamableHttp" explicitly; "sse" is the legacy transport.
• The free tier has a daily limit (see the pricing line above); a paid key raises it.
