What Cursor supports

MCP apps

Display

Runs inline by default; supports inline on desktop.

MCP extensions

Advertises io.modelcontextprotocol/ui.

Emulation model

MCPJam emulates Cursor using anthropic/claude-sonnet-4.5, so tests reflect how this host actually drives your tools.

How to test your MCP server against Cursor

Run npx @mcpjam/inspector@latest, connect the server config you already use, and select Cursor. MCPJam drives your server the way this host does, including its model (anthropic/claude-sonnet-4.5), so you see the tool calls it actually makes instead of guessing from a bug report.

From there, Trace shows every step from prompt to response, the OAuth Debugger shows where authorization breaks, and Evals score whether the model picks the right tool across realistic requests. All of it runs locally, free and open source.
