Frequently asked questions
Grasshopper scores F on Supergood's API Report Card. No public API. Grasshopper publishes no API documentation and runs no developer program; the only sanctioned surface is a limited Zapier integration. The mobile-api.grasshopper.com endpoint behind the official apps is undocumented and unsupported for third parties.
Without a usable official API, teams fall back on manual exports, file drops, or one-off vendor integrations. The other option is an unofficial API layer like Supergood that automates the authenticated web app directly. Site terms may apply to any integration approach, and how they apply is a determination each team makes for itself.
Grasshopper is a cloud-based virtual phone system marketed to entrepreneurs and small businesses.
Horizontal SMB communications / virtual phone. The explicit target market is entrepreneurs, solopreneurs, freelancers, and small businesses (typically under ~20 employees). Solo founders/consultants who want to separate work and personal calls on one device. Real estate agents publishing a single contact number that routes to their cell.
Moderate within its niche, low overall. 150K+ stated customers is meaningful for the entrepreneur/SMB virtual-phone segment, but the company has lost ground in recent years to OpenPhone (Quo), Dialpad, RingCentral, and Google Voice for Business.
Data held by Grasshopper is communications metadata and content: call logs (numbers, timestamps, durations), voicemail audio and transcriptions, SMS/MMS message history, contact lists, call recordings (paid add-on), and account/billing data.
Grasshopper launched in 2003 (originally as GotVMail) and was acquired by Citrix in 2015, then carried into LogMeIn / GoTo.

Supergood's grades measure one thing: can a customer's engineering team get their own data out programmatically? Supergood checks six things (whether a real API exists, how access is gated, data coverage, auth quality, docs and developer experience, and stability) and rolls them into a letter grade. Supergood re-verifies grades, and they only move on evidence.
Not that we could find. As of August 2026 there is no official Grasshopper MCP server in any public registry, and no maintained community server we're aware of. We re-verify this periodically — report an inaccuracy below if we missed one.
Not natively. Grasshopper doesn't publish an MCP server, so MCP clients like Claude, Cursor, and Codex have nothing to connect to out of the box. If that changes, this page will reflect it.
