Moltline Studio

Moltline Studio provides production-grade tooling for AI agents: 14 hosted Model Context Protocol (MCP) servers and 138 free agent skills in the SKILL.md format.

The MCP servers cover code review, time and date operations, data analysis, business math, content creation, education, governance auditing, text humanizing, commerce math, outreach, personal productivity, research, and SKILL.md linting. Each one runs over Streamable HTTP, so any compatible client (Claude Desktop, Claude Code, Cursor, and others) connects by pasting a URL. There is no account, no API key, and no credential required for the free tier, which includes more than 35 working tools and is free permanently. A zero-dependency open-source stdio bridge is available for clients that only speak the stdio transport.

The 138 agent skills are open source and free, each a self-contained SKILL.md file with explicit procedures and boundaries that drops into any skill-compatible agent.

Premium tools across all servers unlock with a single All-Access license at 19 USD per month, payable by card or cryptocurrency. Every server has been independently audited and carries an MCPize Verified A grade, and the site publishes machine-readable discovery documents so autonomous agents can find and use the tools without human involvement.
