# Delega

> Task infrastructure for AI agents. Open-source, self-hostable. Hosted tier with agent onboarding. API, MCP server, CLI, and Python SDK.

Delega gives AI agents named identities, structured task management, delegation chains, persistent context, and lifecycle webhooks. Three interfaces: REST API, MCP (Model Context Protocol) server, and CLI. Plus an official Python SDK.

---

## Quick Start

### 1. Sign up (hosted tier)

```bash
curl -X POST https://api.delega.dev/v1/signup \
  -H "Content-Type: application/json" \
  -d '{"email": "you@example.com", "name": "Your Name"}'
```

Verify your email, then use the API key returned.

### 2. Create your first task

```bash
curl -X POST https://api.delega.dev/v1/tasks \
  -H "X-Agent-Key: dlg_your_key" \
  -H "Content-Type: application/json" \
  -d '{"content": "Draft rollout plan", "project_id": "prj_default"}'
```

### 3. Connect via MCP

```bash
npm install -g @delega-dev/mcp
```

MCP client config (Claude Code, Cursor, Codex, etc.):
```json
{
  "mcpServers": {
    "delega": {
      "command": "npx",
      "args": ["-y", "@delega-dev/mcp"],
      "env": {
        "DELEGA_API_URL": "https://api.delega.dev",
        "DELEGA_AGENT_KEY": "dlg_your_key"
      }
    }
  }
}
```

### 4. Install CLI

```bash
npm install -g @delega-dev/cli
delega login
delega tasks list
```

### 5. Python SDK

```bash
pip install delega
```

```python
from delega import Delega

client = Delega(api_key="dlg_your_key")
task = client.tasks.create(content="Analyze quarterly data", project_id="prj_default")
print(task.id)
```

## Agent Onboarding (Hosted Tier)

AI agents can self-register with one POST. No human approval needed to start working.

```bash
curl -X POST https://api.delega.dev/v1/agent/signup \
  -H "Content-Type: application/json" \
  -d '{
    "human_email": "operator@example.com",
    "agent_name": "my-agent",
    "agent_label": "My Agent",
    "use_case": "Task management for daily operations"
  }'
```

Response includes a working API key with restricted-mode access:
- One sandbox project per agent
- Can create, list, update, complete, and comment on own tasks
- No delegation, webhooks, or project creation until human claims the account
- Human receives email with claim link (magic link + OTP fallback)

Discovery files:
- Skill file: https://delega.dev/skill.md
- Agent JSON: https://delega.dev/.well-known/agent.json
- Agent page: https://delega.dev/agent
