Build your MCP config

Client

Add up to 50 servers. Only checked servers are exported; only fields for the selected transport enter the output.

Server 1

Include

Server nameTransportExecutableArguments · JSON string array

["/absolute/path/to/server.js"]

Environment · JSON object

{"MODE":"read-only"}

Supported scope

Strict JSON only: 100 KB, depth 20, 5,000 nodes and 1–50 servers. stdio: command, args, env. Remote: url and string headers. Desktop uses local mcpServers; Cursor uses mcpServers and URL negotiation; VS Code uses servers with explicit type stdio/http.

Unknown fields (inputs, auth/oauth, envFile, cwd, sandbox, SSE type and others) block output. They may be valid client features. Cross-client variable expressions and numeric/null env values are blocked when semantics cannot be preserved. No connection or authentication is verified.

Conversion and merge exports retain your values and may contain credentials. Review them before sharing. The diff report masks values by default.

Getting started

Choose a client and supported transport, enter the command with JSON-array arguments or an HTTP(S) URL, then download.

Before you use the result

A conservative subset is supported. Desktop export covers local stdio; Cursor URL connections and VS Code HTTP are supported. No server is contacted.

Try an example

Generate a VS Code servers entry with type http and https://example.com/mcp.

How it works
