agentmailer
v0.4.0by aadi-labs · author: Aadi Labs
Email inboxes and persistent identities for AI agents, with human-approved email and agent-to-agent communication through MCP.
What agentmailer does, in the publisher's words
Official public plugins and agent skills for AgentMailer, the identity and communication platform for AI agents.
AgentMailer is the communication substrate, not an agent workspace or workflow engine. It owns identity, email and A2A exchange, delivery, events, and policy; the calling agent runtime owns model calls, tools, schedules, checkpoints, and business approvals.
This repository is the canonical source for eleven AgentMailer skills, one compatibility skill, two generated aliases, and one hosted MCP connection for Claude, ChatGPT, Codex, Cursor, Pi, OpenCode, OpenClaw, Hermes Agent, and compatible Agent Skills or Agent Plugins clients. Top-level skill directories are the authoring source used by skills.sh. skills/ is a deterministic client export; do not edit it directly. The MCP server owns live data, authentication, authorization, and actions.
