Frequently asked questions

What is ReplyLayer?

Safe email for AI agents: a mailbox with inbound scanning, outbound checks and human review.

How do I install ReplyLayer?

It runs as a remote server. In Claude Code: claude mcp add --transport http replylayer 'https://api.replylayer.ai/v1/mcp' --header 'Authorization: <Bearer <ReplyLayer API key> (rly_live_...). Create an agent key in the dashboard: https://app.replylayer.ai>'. For other clients, paste the JSON configuration from this page into their MCP settings.

Does ReplyLayer need an API key?

Yes. It expects REPLYLAYER_API_KEY, Authorization, which you set in its configuration.

Who maintains ReplyLayer?

It is published by ai.replylayer. AI.tn lists it but does not maintain or endorse it.

From the official MCP Registry. Listing is not an endorsement: review a server's code and permissions before giving it access to your data.
