You can add a new MCP server from the Claude Code CLI. But modifying the json file directly is simpler!
- Open the Claude Code configuration file (it should be in
~/.claude.json). - Find the
projects>mcpServerssection and add the following details and save the file:
{
"projects": {
"mcpServers": {
"mssql": {
"command": "npx",
"args": [
"-y",
"mcp-node-mssql"
],
"env": {
"DB_HOST": "localhost",
"DB_PORT": "1433",
"DB_USERNAME": "<username>",
"DB_PASSWORD": "<password>",
"DB_DATABASE": "<database>",
"CONNECTION_TIMEOUT": 600000,
"REQUEST_TIMEOUT": 300000
"DB_ENCRYPT": "false",
"DB_ENABLE_ARITH_ABORT": "false",
"DB_TRUST_SERVER_CERTIFICATE": "false",
"TRUSTED_CONNECTION": "false"
}
}
}
}
}Before doing anything else, please make sure you are running the latest version!
If you run into problems using this MCP server, please open an issue on GitHub!
npm installnpm run buildTo test your local development version of the MCP server rather than using the published package, follow these steps:
- Build the project:
npm run build- Create or modify your
mcp.jsonfile to reference your local build:
{
"mcpServers": {
"mssql": {
"command": "node",
"args": [
"/path/to/your/local/mcp-node-mssql/dist/index.js"
],
"env": {
"DB_HOST": "localhost",
"DB_PORT": "1433",
"DB_USERNAME": "<username>",
"DB_PASSWORD": "<password>",
"DB_DATABASE": "<database>",
"CONNECTION_TIMEOUT": 600000,
"REQUEST_TIMEOUT": 300000
"DB_ENCRYPT": "false",
"DB_ENABLE_ARITH_ABORT": "false",
"DB_TRUST_SERVER_CERTIFICATE": "false",
"TRUSTED_CONNECTION": "false"
}
}
}
}-
Place this
mcp.jsonfile in one of the following locations:- For Cursor: In your home directory (
~/.cursor/mcp.json) or in your project directory (.cursor/mcp.json) - For Windsurf: Use the MCP Configuration Panel to add the custom server
- For Cursor: In your home directory (
-
Restart your AI assistant (Cursor or Windsurf) to load the new configuration.
This allows you to instantly test changes to the MCP server without having to publish a new version.
