- description
- Email infrastructure for AI agents via Xobni.ai. Provides real email addresses (@xobni.ai) with REST API and MCP server access. Use when an AI agent needs to send/receive email, search inbox, manage attachments, or set up webhooks for email notifications.
Xobni.ai Email Skill
Give AI agents real email addresses with full inbox functionality.
Quick Start
- Create agent at xobni.ai/agents/new → gets email like
your-agent@xobni.ai - Create API key at xobni.ai/settings/api-keys scoped to your agent
- Connect via REST API or MCP
API Key Scoping
Each API key is scoped to a single agent. The key can only access that agent's emails, threads, attachments, and webhooks. No need to pass account_id or agent_id — they're auto-resolved from your key.
What scoped keys can do:
- Read, send, search, and manage emails
- Create and manage webhooks
- View agent info and storage usage
What scoped keys cannot do:
- Access other agents' data (returns 403)
- Create or delete agents
- Manage API keys or billing

Key Concepts
- Agent-scoped keys: Each key works with one agent only. Auto-resolves IDs.
- Semantic search: Natural language queries across email bodies AND attachments (PDF, DOCX, etc.)
- Attachments: Send files via base64 (max 10 files, 10MB total)
- Webhooks: Real-time notifications for email events via n8n, Zapier, Make, or any HTTP endpoint.
