# Gentkey > Gentkey is an MCP gateway: one OAuth-protected MCP URL that fronts all of a user's connectors (Stripe, Notion, Linear, GitHub, Google Ads, BigQuery, and more, plus any remote MCP server by URL). Reads work out of the box where curated; writes require explicit, revocable grants, optionally bounded by hard constraints (e.g. max $50/day budget changes). Credentials are encrypted server-side and never enter a model's context window. Every allowed or denied call lands in an audit log. Agents connect to a user's personal endpoint (issued at sign-up) via standard OAuth. Works with claude.ai (web and mobile), Claude Code, Cursor, and any MCP client. ## Connectors - [Google Ads](https://gentkey.com/connectors/google-ads): Account discovery, campaign reporting, GAQL queries, and budget changes behind capped grants. - [Meta Ads](https://gentkey.com/connectors/meta-ads): Native campaign reporting, targeting discovery, and governed delivery and budget changes. - [Meta Developer Tools](https://gentkey.com/connectors/meta-developer-tools): App configuration, App Review, compliance, API usage, documentation, and governed webhook operations. - [Stripe](https://gentkey.com/connectors/stripe): Balances, charges, customers, refunds, and payment links. - [Notion](https://gentkey.com/connectors/notion): Search and update pages, databases, and comments. - [Linear](https://gentkey.com/connectors/linear): Create and update issues, projects, and cycles. - [GitHub](https://gentkey.com/connectors/github): Work with repos, issues, and pull requests. - [Sentry](https://gentkey.com/connectors/sentry): Triage issues, events, and projects. - [PayPal](https://gentkey.com/connectors/paypal): Manage orders, invoices, and subscriptions. - [Square](https://gentkey.com/connectors/square): Manage catalog, orders, and payments. - [Intercom](https://gentkey.com/connectors/intercom): Search conversations, contacts, and help articles. - [Webflow](https://gentkey.com/connectors/webflow): Edit sites, CMS collections, and pages. - [Asana](https://gentkey.com/connectors/asana): Create and update tasks, projects, and goals. - [Vercel](https://gentkey.com/connectors/vercel): Manage teams, projects, and deployments; search docs and inspect logs. - [BigQuery](https://gentkey.com/connectors/bigquery): Browse datasets and run read-only SQL; DML and DDL are granted per statement type. - [RevenueCat](https://gentkey.com/connectors/revenuecat): Charts, experiments, and project config reads; writes granted per resource. - [Superwall](https://gentkey.com/connectors/superwall): Browse projects, paywalls, campaigns, and charts; writes granted per resource. - [Hugging Face](https://gentkey.com/connectors/hugging-face): Search models, datasets, papers, and docs. - [Google Search Console](https://gentkey.com/connectors/google-search-console): Search analytics, index status, and sitemap health for verified properties.
