🚀 OpenMCP

OpenMCP is a standard for converting web APIs into MCP servers and an open - source server registry that adheres to this standard.

OpenMCP serves two main purposes:

It is a standard for converting web APIs into MCP servers.
It is an open - source server registry that follows this standard.

Each OpenMCP server enables MCP clients to make requests to specific web APIs in an efficient token - based manner. Together, the servers in the registry represent a wide range of services, empowering underlying client LLMs to obtain data and perform operations in many fields on behalf of their users.

Requirements:

Node.js v18 or higher (including npx and npm)

Claude Desktop

npx @open-mcp/config add {server-id} \
  ~/Library/Application\ Support/Claude/claude_desktop_config.json \
  --ENV_VAR=abc123

Now restart Claude Desktop to load the tools.

Cursor

Run the following command in the root directory of the project or to add all Cursor projects to the project directory:

npx @open-mcp/config add {server-id} \
  .cursor/mcp.json \
  --ENV_VAR=abc123

Now go to Cursor > Settings > Cursor Settings, then click MCP to ensure the server is enabled.

Other Clients

npx @open-mcp/config add {server-id} \
  /path/to/config.json \
  --ENV_VAR=abc123

Alternative

If you don't want to use the CLI, you can manually install the package using npm and then add a node command in the client configuration, specifying the absolute path to dist/index.js. See the README of each server for more details.
