How to Set Up and Use MCP Clients Julia
ModelContextProtocolClients.jl is a Julia package that provides a lightweight MCP client layer, enabling Julia programs to connect to and communicate with any MCP-compatible server over stdio or SSE transports. It lets you discover available tools, call them with typed arguments, and manage multiple server connections through a single collector instance.
Prerequisites
- Julia 1.9 or newer installed on your system
- Access to at least one running MCP server (local or remote)
- Familiarity with Julia's package manager (Pkg)
- Node.js if connecting to Node-based MCP servers via stdio
Install the package
Add ModelContextProtocolClients to your Julia environment using the built-in package manager.
using Pkg
Pkg.add("ModelContextProtocolClients")Import and create a collector
Import the package and instantiate an MCPClientCollector, which holds connections to multiple servers.
using ModelContextProtocolClients
collector = MCPClientCollector()Connect to a server via SSE
Use MCPClient with the :sse transport type to connect to a remote server over HTTP Server-Sent Events.
client = MCPClient("https://mcp.bitte.ai/sse", :sse)
tools = list_tools(client)Connect to a local stdio server
Use add_server() to spawn a local MCP server as a subprocess and register it with the collector. Optionally provide a setup_command to build the server first.
add_server(collector, "puppeteer", "path/to/puppeteer-server.js",
setup_command=`bash -c "cd path && npm install && npm run build"`)List tools and call one
Retrieve the list of available tools from a connected server, then invoke a specific tool by name with a Dict of arguments.
tools = list_tools(collector)
response = call_tool(collector, "puppeteer", "puppeteer_navigate",
Dict("url" => "https://example.com"))Discover servers from a config file
Load server definitions from an mcp.json config file so you do not have to hard-code each server connection in your code.
load_mcp_servers_config(collector, "mcp.json")
list_clients(collector)Disconnect all servers when done
Clean up all active connections gracefully before your program exits.
disconnect_all(collector)MCP Clients Julia Examples

}Prompts to try
After connecting to an MCP server from a Julia script or notebook, use these patterns to explore and invoke tools.
- "List all tools available from the puppeteer server"
- "Navigate to https://example.com using the puppeteer server and return the page title"
- "Connect to the time MCP server and get the current UTC time"
- "Auto-discover all MCP servers in the ./servers directory and list their tools"Troubleshooting MCP Clients Julia
add_server() hangs or times out when connecting to a local server
Ensure the server process actually starts and writes its initialization message to stdout. Check that the command path is correct and the server binary has execute permissions. Use explore_mcp_servers_in_directory() to verify the server is detectable.
call_tool() returns an error saying the tool was not found
Run list_tools(collector) first to confirm the tool name exactly. Tool names are case-sensitive and may include prefixes added by the server. Make sure you are calling the tool on the correct server ID registered with the collector.
SSE connection drops intermittently
SSE connections depend on HTTP keep-alive. If the remote server has a short idle timeout, reconnect by calling add_server() again with the same server ID. Consider wrapping calls in a try/catch to detect disconnections and retry.
