INTEGRATIONS
Connect the client
you already use.
Each page has setup steps for that host. Documentation stays on docs.mermail.app.
Claude
Install the Mermail plugin so Claude can provision an inbox, read verification mail, and finish paid workflows without leaving the terminal.
Open setupChatGPT
Add Mermail as a custom ChatGPT connector. Streamable HTTP plus OAuth — no API key in the connector. Then ChatGPT can list mailboxes, read mail, and finish paid workflows.
Open setupCodex
Install the Mermail plugin so Codex maps MERMAIL_API_KEY into MCP, loads 11 skills, and can list mailboxes, draft replies, and complete checkout.
Open setupCursor
Install the hosted MCP server with OAuth. Cursor discovers Protected Resource Metadata after a 401, then your agent can read mail and act on payments inside the IDE.
Open setupOpenClaw
Point OpenClaw at hosted MCP with Streamable HTTP and x-api-key. Probe the connection, then let the agent manage inboxes and payment receipts.
Open setupHermes
Add Mermail as a Streamable HTTP MCP server in Hermes Agent. OAuth opens a browser, then the agent can list mailboxes, read mail, and finish paid workflows in chat.
