Quick start
Run the command in your terminal
npx @mcpjam/inspector@latest
 
After installing the package, you should see a link to localhost. Open that link up to see the inspector.
If you don’t have Node.js installed, check out our desktop app.
Connect to your first MCP server
Click on “Add server” and connect to your first MCP server
npx -y @modelcontextprotocol/server-everything
 
Once you hit submit, you should see the connection status as “Connected”. This page is your server connections page. You can connect to multiple MCP servers simulatenously on MCPJam.
@modelcontextprotocol/server-everything is the example server from Anthropic
 
Go to the “Tools” tab. You’ll be able to see all of the MCP tools server-everything has. Tools tab lets you test individual tools with configured params.
Try testing out the add tool and set params for a and b. Upon hitting “Execute”, you should see the tool’s return value on the bottom.
