If you build and market the same product, Cursor is a reasonable place to do both. Adding AdWhispr as an MCP server means the agent you already use can pull live competitor ad data and launch campaigns.
Step 1: Install it
The fastest route is the one-click install from the Cursor integration page. Approve the install prompt when Cursor asks.
If you would rather do it by hand, keep reading.
Step 2: Add the server manually
Open Cursor settings with Cmd+, on Mac or Ctrl+, on Windows, then go to Tools & MCP.
Click New MCP Server. Cursor opens your mcp.json. Add the AdWhispr entry:
{
"mcpServers": {
"adwhispr": { "url": "https://adwhispr.com/api/mcp" }
}
}
Save the file.
Step 3: Restart and authorize
Fully quit and reopen Cursor. A partial reload is not enough, and this is the step people skip when the server shows as unavailable.
When Cursor prompts you to sign in to AdWhispr, approve it.
Step 4: Test it
Ask the agent:
Use AdWhispr to research Gymshark's Meta ads and show me their longest-running winner.
You should get a real ad with a days-running count.
FAQ
The server shows as unavailable, what now?
Quit Cursor completely and reopen it. Cursor picks up new MCP servers on a full restart, not on a window reload. If it still fails, check mcp.json for a trailing comma or a missing brace.
Does this work in Windsurf as well?
Yes, with a slightly different key. Windsurf expects serverUrl rather than url in its mcp_config.json.
Do I need to install anything with npm?
No. The remote server needs no local install. There is an npm bridge (npx adwhispr-mcp-server config) for clients that expect a local command, but Cursor does not need it.
Can other MCP clients use the same URL?
Yes. Any MCP-capable client can point at https://adwhispr.com/api/mcp, including Claude Code, Codex and Perplexity.
