About

The Agent Communication Protocol (ACP) is an open interoperability standard designed to enable seamless communication between AI agents, applications, and human users. It provides a standardized RESTful API that supports synchronous and asynchronous interactions, streaming communication, long-running tasks, and both stateful and stateless operations. ACP is framework-agnostic, allowing agents built with technologies such as BeeAI, LangChain, CrewAI, or custom solutions to work together without requiring changes to their internal architecture. The protocol supports all content modalities through MimeTypes, making it flexible enough to handle text, images, audio, video, and custom data formats. ACP also includes capabilities for online and offline agent discovery, helping organizations find and connect compatible agents across different environments.

About

OpenMail gives AI agents a dedicated email address. Provision an inbox with one CLI command or API call, each agent gets its own address, not a shared inbox or forwarding alias. Inbound email arrives instantly via webhook or WebSocket, parsed and threaded, with no polling required. Replies land in context so agents can respond without any new interface on the human side. Attachments: PDFs, CSVs, images, spreadsheets, Word documents are automatically converted to LLM-ready text; the agent never touches raw MIME. The API is small by design: one call to provision, standard calls to send, webhooks or WebSocket to receive. Integrates with LangChain, n8n, Make, Vercel AI SDK, and OpenClaw. Custom domains supported. Runs in the EU, GDPR-covered, 99.9% uptime SLA, SOC 2 in progress.

Pros & Cons from Real Users

Pros

  • I was playing with OpenClaw quite a bit when I hit a roadblock, which is it can't sign up to services? Luckily, OpenMail was here to help, I own them one.

Cons

  • The onboarding was a bit tricky with so many integrations to choose from. But I got some help from Discord, fast responses too.
