Why this matters
Cursor speaks MCP natively. Engineers and PMs who already write code in Cursor can manage their marketing stack alongside it — adding a contact while writing a webhook handler, scheduling a campaign while writing the React Email template, checking a segment by estimating its size.
What you get
- MCP support is first-class in Cursor — no plugin marketplace required.
- Same API key works for the REST API and the MCP server.
- Cursor's composer can chain ReachOut tool calls with file edits — write the template and schedule the send in one prompt.
Setup in 4 steps
- Generate a ReachOut API key.Studio → Organization settings → API keys → Generate API key, then grant it the editor role on your project. Copy the key.
- Add the MCP server in Cursor settings.Cursor → Settings → MCP → Add server. Set the transport to "http" and point at https://api.usereachout.com/mcp. Add the bearer token in headers.
- Reload the workspace.Cursor picks up the MCP server within ~5 seconds. ReachOut tools appear under the / menu in the composer.
- Try a chained prompt.Ask: "create a contact for jane@acme.com and add her to the Newsletter contact list." Cursor calls create_contact, then add_contact_list_members.
