Primitive AI platform integrations
primitive.dev gives AI agents a real email identity. It connects to the major agent platforms through open, machine-readable manifests — so an agent on any of these platforms can discover and use Primitive without a custom integration.
ChatGPT
Primitive publishes a standard plugin manifest describing the product, its OpenAPI spec, and how a model should use it. Point a ChatGPT-compatible runtime at the manifest to let it send and receive email through Primitive.
Claude
Primitive runs a hosted Model Context Protocol (MCP) server. Add it as a connector in Claude (claude.ai, Claude Desktop, or Claude Code) to give Claude the Primitive email tools — list, search, read, send, and reply. Auth is OAuth; a credential-free demo tool lets Claude try a send before you connect an account.
Any MCP-compatible agent
Because the integration is a standard MCP server, any MCP-aware client can use it — not just one vendor. The server is also listed in public MCP registries so agents can discover it by name. Discovery lives at a predictable URL.
Coding agents
For coding agents — Claude Code, Codex CLI, OpenCode, Amp — the primitive chat skill installs in one command and is published on skills.sh under primitivedotdev/skills.

Every integration above is built on the same open surface: the developer resources, the OpenAPI spec, and the hosted MCP server. There is nothing platform-specific to reverse-engineer — discover the surface and call it.
