Cucutime MCP server & API

Personalized kids-song tools for AI agents and apps, from Cucutime. A hosted remote MCP server (Streamable HTTP) plus a small REST API.

• MCP endpoint: https://cucutime.org/mcp

• Official MCP Registry: org.cucutime/mcp

• Docs: https://cucutime.org/developers · OpenAPI: https://cucutime.org/api/openapi.json · llms.txt

This repository has the public registry manifest, client configs and examples. The server itself is hosted by Cucutime, so there is nothing to install.

Tools

The keyless tools use no generative AI and are safe for any app. The two AI tools are for adult-facing apps only (parents, teachers, creators), as required by the developer terms. Get a free trial key at https://cucutime.org/developers.

Send first names only: no surnames or other personal data.

# keyless tools
claude mcp add --transport http cucutime https://cucutime.org/mcp
# with a developer key (adult-facing apps only)
claude mcp add --transport http cucutime https://cucutime.org/mcp --header "Authorization: Bearer cct_YOUR_KEY"

Cursor (.cursor/mcp.json) and other clients that support remote servers with headers:

{ "mcpServers": { "cucutime": { "url": "https://cucutime.org/mcp", "headers": { "Authorization": "Bearer cct_YOUR_KEY" } } } }

Omit headers to use the keyless tools only. A ready-made project config is in .mcp.json.

Claude Desktop (claude_desktop_config.json, via mcp-remote):

{ "mcpServers": { "cucutime": { "command": "npx", "args": ["-y", "mcp-remote", "https://cucutime.org/mcp", "--header", "Authorization:Bearer cct_YOUR_KEY"] } } }

Claude.ai and ChatGPT custom connectors: add https://cucutime.org/mcp with no authentication to use the three keyless tools. These connectors can't send a static API key yet, so use the AI tools from a client that sends headers, or through the REST API.

Try it in 10 seconds (no key)
