Side by side
| Question | Kin | Claude connectors | ChatGPT and Codex | Zapier MCP | Composio |
|---|---|---|---|---|---|
| More than one account of the same service | Yes, for any service. Each account is its own connection with its own rules, and the app asks which one. | Not confirmed from their pages | Not confirmed from their pages | Each app has a default connection. The agent can use another one when you ask. Source, Nov 3, 2026 | With multi-account mode on. By default, a session uses one account per toolkit. Source, Nov 3, 2026 |
| Rules for each tool | Allow, Ask me or Block per action, plus a level per account. | Always allow, Needs approval or Blocked, for a single tool or a group of tools. Source, Nov 3, 2026 | Codex: approval per MCP tool with approval_mode in config.toml. Source, Nov 3, 2026 | In managed mode, you set up the server's tools at mcp.zapier.com. Source, Nov 3, 2026 | Approval by tool tag or tool name, set when a session is created in code. Marked experimental. Source, Nov 3, 2026 |
| Approving a single call | On the web, on Kin for iPhone and Apple Watch (TestFlight beta) and Kin for Android, with a note back to the app. | Claude can ask before it uses a tool: Allow once or Always allow. Source, Nov 3, 2026 | ChatGPT: write actions need confirmation by default. Source, Nov 3, 2026 | Not confirmed from their pages | Clients that support MCP elicitation, such as Claude Code, ask the user. Other clients deny those calls by default. Source, Nov 3, 2026 |
| Settings shared across AI apps | Rules are checked on Kin's server, so one change holds in every app at once. | Connectors work across Claude's apps: web, desktop, mobile, Claude Code and Cowork. Source, Nov 3, 2026 | Codex keeps its MCP settings in config.toml, shared by the ChatGPT desktop app, Codex CLI and IDE extension. ChatGPT on the web doesn't read it. Source, Nov 3, 2026 | Every MCP client on one server uses the same apps and actions. Source, Nov 3, 2026 | One shared MCP URL, with setup steps for Claude, ChatGPT, Cursor, Codex and other clients. Source, Nov 3, 2026 |

One custom connector on the Free plan. Source, Nov 3, 2026 | ChatGPT on the web adds a custom MCP server. Source, Nov 3, 2026 | Your own private integrations, built on the Zapier Developer Platform. Source, Nov 3, 2026 | Through Custom MCP, for remote servers. Marked experimental. Source, Nov 3, 2026 |
Where Kin fits.
Kin is for people who use several AI apps with their own accounts and want one set of rules for all of them: more than one account per service, approvals on your phone, a record of every call, and Pause to stop every app at once. How Pause works
What Kin doesn't do.
- Kin is hosted. There is no version to run yourself.
- Gmail and Google Drive are invite-only in Kin for now.
- ChatGPT adds Kin as a custom MCP server on the web, where your workspace's permissions apply (OpenAI's page, read November 3, 2026). ChatGPT setup
- Kin governs what goes through it. A command an agent runs on your computer by itself is outside Kin.
