rating : 2.5 points
downloads : 29
What is the MCP Actions Adapter?
The MCP Actions Adapter is a simple and easy-to-use conversion tool that can convert a Model Context Protocol (MCP) server into an API interface compatible with GPT Actions. This enables developers to easily integrate MCP servers into the GPT ecosystem.How to use the MCP Actions Adapter?
The usage process is very simple: 1) Prepare the configuration file. 2) Start the Cloudflare tunnel. 3) Run the adapter. 4) Configure the API in the GPT builder.Applicable scenarios
It is suitable for developers who want to quickly connect existing MCP servers to the GPT ecosystem, or teams that need to provide custom API capabilities for GPT models.Main features
Protocol conversionConvert the MCP protocol to an API interface compatible with GPT Actions
Simple configurationUse a configuration file format similar to Claude Desktop, which is easy to set up
Tunnel supportBuilt-in support for Cloudflare tunnels, facilitating local development and testing
Advantages and limitations
Advantages
