Paste an MCP config from any client and get it back in the format VS Code actually reads — including the format changes nobody documents.
Config files are for the people who already bought. MCP Showcase gives you one link that shows anyone what your server does, without them configuring anything at all.
From Claude Desktop, Cursor, VS Code, Windsurf or anywhere else. We detect the source format.
Root key, endpoint field, transport type, file format — and whether VS Code can reach a hosted server at all or needs a local bridge.
The result is in the file format VS Code reads, ready to paste into the right location.
MCP standardises the protocol, not the configuration. Moving a server between two clients means changing up to four things, and every one of them fails silently if you miss it — the file parses, the client starts, and the server is simply absent.
.vscode/mcp.json (per workspace) or user settings.json, in JSON.servers here, but
mcpServers, servers, context_servers or
mcp_servers depending on where you are coming from.url for VS Code.
This is the one that catches almost everyone: VS Code uses "servers", while Claude, Cursor and Windsurf all use "mcpServers". A config copied from any of those parses as valid JSON and does nothing at all. VS Code also supports an "inputs" array so a token is prompted for and stored in the OS keychain rather than committed to the repo.
Local stdio servers are mostly portable: the command and its arguments mean the same thing everywhere. What changes is the wrapper — the root key, and for JSON clients the entire file syntax. Headers and environment variables come across as they are, so if your config contains a token, it will be in the output. Everything happens in your browser and nothing is uploaded, but strip it first if you would rather.
Porting a config between clients is work that only ever benefits people who already use your server. It does nothing for the person deciding whether to try it. MCP Showcase gives that person a live playground on the same URL — every tool documented and runnable in a browser, with no file to edit and nothing to restart.
