CommunicationOS provides a standard MCP server implementation that exposes search, thread retrieval, profile lookup, ledger extraction, and message drafting as structured tools. AI agents running in Claude Desktop, Cursor, or custom orchestration frameworks can securely query organizational message history and stage contextual responses within defined permission boundaries.

Every tool call runs under the scopes attached to the token. An agent given read access to one counterparty cannot search the rest of the archive, and every call it makes is written to the audit log.
