ggui vs mercury-invoicing-mcp

ggui: ggui is an open protocol and reference runtime that allows AI agents to generate ephemeral, interactive user interfaces over MCP without writing frontend code. It can be self-hosted and paired with any MCP-aware agent runtime such as Claude Desktop, Cursor, or ChatGPT desktop.; mercury-invoicing-mcp: This MCP server provides full programmatic access to Mercury business banking, including invoicing, with 34 tools, rate limiting, dry-run, and audit logging. It is the first MCP to expose Mercury's Invoicing API for accounts receivable management. Built-in safeguards protect against runaway agents and prompt injection.
