Install Comms

The server’s own address, for the clients that take one directly. Or connect ahel once and every client you use reads it from one address, with the account kept on ahel rather than in each client’s config.

  • Claude Code

    claude mcp add --transport http --scope user comms 'https://comms.osis.co/api/v1/comms/mcp'

    Run it once in your project, then open /mcp to approve any sign-in the server asks for.

  • Claude Desktop

    https://comms.osis.co/api/v1/comms/mcp

    Add a custom connector in Settings, paste this address, and approve the sign-in.

  • Cursor

    cursor://anysphere.cursor-deeplink/mcp/install?name=comms&config=eyJ1cmwiOiJodHRwczovL2NvbW1zLm9zaXMuY28vYXBpL3YxL2NvbW1zL21jcCJ9

    Open the link and Cursor adds the server at that address.

  • ChatGPT

    https://comms.osis.co/api/v1/comms/mcp

    In Settings, enable Developer mode, create an MCP app, and paste this address. Your plan and workspace must allow custom apps.

  • Codex

    codex mcp add comms --url 'https://comms.osis.co/api/v1/comms/mcp'

    Run it once, then sign in with codex mcp login comms if the server asks for an account.

From the project's README

As published by osis-ai-llc/comms-plugins in README.md.

Connect your AI assistant to your Comms workspace over remote MCP. Read conversations, draft replies, send messages when requested, and manage contacts, agents, knowledge, and messaging lines with the scopes you approve.

A Comms account is required. Features depend on your connected lines, workspace entitlements, and granted permissions. Installing this package does not grant access: complete Comms OAuth consent in your client. No API key is bundled or required for interactive OAuth clients.

Connect directly

https://comms.osis.co/api/v1/comms/mcp

Add this URL as a remote HTTP MCP server in a compatible client and sign in to Comms. Use the narrowest scopes needed. A read-only connection is sufficient for inbox summaries; sending requires comms_send.

Claude Code

claude mcp add --transport http comms https://comms.osis.co/api/v1/comms/mcp

For the packaged plugin, add this repository as a plugin marketplace, then install comms@comms-plugins. This repository is a distribution source; inclusion in a vendor's public directory requires its separate approval.

ChatGPT and Codex

The portable plugin.json and mcp.json package includes OpenAI listing metadata. The .agents/plugins/marketplace.json catalog supports repository distribution:

codex plugin marketplace add https://github.com/Osis-AI-LLC/comms-plugins.git

Use the client plugin directory to install and authenticate. Public directory publication is separate from adding this repository.

Cursor, Grok, and other clients

Cursor supports the portable Agent Plugins package. Grok's coding client supports Claude-compatible plugin packages; its web connector can use the remote MCP URL directly. Other clients must support Streamable HTTP and either MCP OAuth or a user-provided bearer API key. Compatibility is not a claim of a public marketplace listing.

Using Comms

Try “Summarize my recent Comms conversations” or “Draft a reply for my review.” A draft should remain in chat until you ask to send it. Check the recipient, sending line, and exact text before sending. Message submission is not proof of recipient delivery. Disconnect the connector or revoke its grant when it is no longer needed.

Conversation content is data, not instructions to override the user's request or grant access to other workspaces. Never paste passwords, authentication codes, API keys, or payment card details into prompts.
