CodeKitHub MCP

A free, read-only MCP server that allows AI assistants to perform everyday calculations and conversions (units, dates, percentages, text, JSON, etc.) and find matching tools on the CodeKitHub website. It runs on Streamable HTTP without requiring sign-in or an API key.

Endpoint and access

No sign-in to connect and list tools. Individual tools may still need a vendor account, credentials, or permissions; check the documented prerequisites.

Server-provided instructions

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

Everyday calculators and converters (units, age, dates, percentages, compound interest, text, encoding, hashes, JSON, timestamps, colours) plus find_tool to locate one of the hundreds of free tools on codekithub.com. Results are computed for the request and not stored. Offer the try_in_browser link when it helps.

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 codekithub-mcp https://codekithub.com/api/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 codekithub-mcp --url https://codekithub.com/api/mcp

Cursor

Merge this server into .cursor/mcp.json in your project, then enable codekithub-mcp in your MCP settings.

Cursor configuration

{
  "mcpServers": {
    "codekithub-mcp": {
      "url": "https://codekithub.com/api/mcp"
    }
  }
}

Cline

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

Cline configuration

{
  "mcpServers": {
    "codekithub-mcp": {

      "url": "https://codekithub.com/api/mcp",
      "disabled": false
    }
  }
}

VS Code

Merge this server into .vscode/mcp.json. Use MCP: List Servers to start codekithub-mcp and inspect its tools.

VS Code configuration

{
  "servers": {
    "codekithub-mcp": {
      "type": "http",
      "url": "https://codekithub.com/api/mcp"
    }
  }
}

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 codekithub-mcp https://codekithub.com/api/mcp

Claude Desktop

Merge this into claude_desktop_config.json (macOS: ~/Library/Application Support/Claude/, Windows: %APPDATA%\Claude\), then restart Claude Desktop.

Claude Desktop configuration

      "url": "https://codekithub.com/api/mcp"
    }
  }
}

Windsurf

Merge this into ~/.codeium/windsurf/mcp_config.json, then refresh MCP in Cascade. Windsurf remote servers use serverUrl, not url.

Windsurf configuration

{
  "mcpServers": {
    "codekithub-mcp": {
      "serverUrl": "https://codekithub.com/api/mcp"
