Which servers in the official MCP registry are LogicCommons'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 namecom.logiccommons/calculatorsverified in the MCP registry

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

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.

  • search_calculators

    Search the LogicCommons calculator catalog by keyword and optional category. Returns matching published calculators with slug, name, summary, category, a citation URL, and trust metadata.

How to connect

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

{
  "mcpServers": {
    "calculators": {
      "type": "http",
      "url": "https://mcp.logiccommons.com/mcp"
    }
  }
}

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.
