Charlie HR (commonly stylized 'CharlieHR' or just 'Charlie') is a London-based cloud HR platform purpose-built for UK small businesses and startups.
Vertical: Enterprise / HR / ERP (Sanity vertical mapping: Enterprise/HR/ERP; Airtable bucket: misc). Centralized employee records and HR data store. New hire onboarding workflows (digital paperwork, equipment checklists, welcome flows). Time off / leave management (request, approval, balance tracking, calendar sync).

HR system of record for UK SMBs: employee PII (name, DOB, address, NI number, bank details), employment history, salary records, leave allowances/balances, performance reviews, onboarding documents, right-to-work documentation.
Founded 2015-2016, ~10-11 years old as of 2026. Cloud-native from inception (not a re-platformed legacy product).
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 Charlie HR 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. Charlie HR 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.
