Introduction to OpenMCP

OpenMCP is both:

1. a standard for converting web APIs into MCP servers
2. an open source registry of servers which follow the standard

Each OpenMCP server gives MCP clients the ability to make requests to a particular web API in a token-efficient way. Together the servers in the registry represent a broad range of services, empowering the underlying client LLMs to fetch data and perform actions on behalf of their users across many domains.
