# Multiple Accounts Configuration 🔐

## Overview

This project supports **multiple accounts for the same service**:

- Multiple GitHub accounts (personal, work, alt)
- Multiple Cloudflare accounts (prod, staging, dev)
- Multiple GitLab instances (internal, external)

Each account is:

1. Bound to a **unique environment variable name**, and  
2. Exposed as a **separate MCP server** in `opencode.jsonc`.

> 🔒 **Security Note:** Never commit tokens to git. Keep them in your shell environment, a `.env` file that is `.gitignore`d, or a secrets manager.

---

## 1. Export Tokens with Unique Variable Names

Use descriptive names that encode both **service** and **purpose**.

**Pattern:**  
`<SERVICE>_<RESOURCE>_<ENV or PURPOSE>`

Examples:
- `GITHUB_TOKEN_WORK`
- `CLOUDFLARE_API_TOKEN_PRODUCTION`
- `GITLAB_TOKEN_INTERNAL`

### Shell Export (for session-based or profile)

```bash
# GitHub – multiple accounts
export GITHUB_TOKEN_SECONDARY="ghp_another_token_here"
export GITHUB_TOKEN_WORK="ghp_work_account_token"
export GITHUB_TOKEN_PERSONAL="ghp_personal_account_token"

# Cloudflare – multiple accounts
export CLOUDFLARE_API_TOKEN_PRODUCTION="prod_token_here"
export CLOUDFLARE_ACCOUNT_ID_PRODUCTION="prod_account_id"

export CLOUDFLARE_API_TOKEN_STAGING="staging_token_here"
export CLOUDFLARE_ACCOUNT_ID_STAGING="staging_account_id"

# GitLab – multiple instances
export GITLAB_TOKEN_INTERNAL="glpat_internal_token"
export GITLAB_URL_INTERNAL="https://gitlab.internal.company.com"

export GITLAB_TOKEN_EXTERNAL="glpat_external_token"
export GITLAB_URL_EXTERNAL="https://gitlab.com"
```

### .env File (recommended for project isolation)

```bash
# .env (remember to add this to .gitignore)
CLOUDFLARE_API_TOKEN_PRODUCTION=prod_token
CLOUDFLARE_ACCOUNT_ID_PRODUCTION=prod_account_id

CLOUDFLARE_API_TOKEN_STAGING=staging_token
CLOUDFLARE_ACCOUNT_ID_STAGING=staging_account_id
```

Then load in shell:

```bash
set -a
source .env
set +a
```

---

## 2. Add MCP Entries in `opencode.jsonc`

Each account becomes its own MCP entry, wired to its own env vars:

```jsonc
// Secondary GitHub account
"github_secondary": {
  "type": "local",
  "command": ["npx", "-y", "@modelcontextprotocol/server-github"],
  "environment": {
    "GITHUB_PERSONAL_ACCESS_TOKEN": "{env:GITHUB_TOKEN_SECONDARY}"
  },
  "enabled": false
},

// Production Cloudflare account
"cloudflare_prod": {
  "type": "local",
  "command": ["npx", "-y", "@modelcontextprotocol/server-cloudflare"],
  "environment": {
    "CLOUDFLARE_API_TOKEN": "{env:CLOUDFLARE_API_TOKEN_PRODUCTION}",
    "CLOUDFLARE_ACCOUNT_ID": "{env:CLOUDFLARE_ACCOUNT_ID_PRODUCTION}"
  },
  "enabled": false
},

// Staging Cloudflare account
"cloudflare_staging": {
  "type": "local",
  "command": ["npx", "-y", "@modelcontextprotocol/server-cloudflare"],
  "environment": {
    "CLOUDFLARE_API_TOKEN": "{env:CLOUDFLARE_API_TOKEN_STAGING}",
    "CLOUDFLARE_ACCOUNT_ID": "{env:CLOUDFLARE_ACCOUNT_ID_STAGING}"
  },
  "enabled": false
},

// Internal GitLab instance
"gitlab_internal": {
  "type": "local",
  "command": ["npx", "-y", "@modelcontextprotocol/server-gitlab"],
  "environment": {
    "GITLAB_TOKEN": "{env:GITLAB_TOKEN_INTERNAL}",
    "GITLAB_URL": "{env:GITLAB_URL_INTERNAL}"
  },
  "enabled": false
}
```

---

## 3. Enable Per-Agent (Recommended) or Globally

**Recommended:** Enable accounts per agent for isolation.

```jsonc
"agents": {
  "cloudflare-ops": {
    "tools": {
      "cloudflare_prod": true,      // Production account
      "cloudflare_staging": true,    // Staging account
      "github_secondary": true,      // Secondary GitHub
      "gitlab_internal": true        // Internal GitLab
    }
  },
  "security-audit": {
    "tools": {
      "cloudflare_prod": true,       // Only production for audits
      "github_secondary": false      // Disable secondary for security
    }
  }
}
```

Global enable (less strict, use sparingly):

```jsonc
"tools": {
  "cloudflare_prod": true,
  "github_secondary": true
}
```

> 🔑 **Principle:** Production credentials should only be wired into a few, tightly-scoped agents (e.g., `cloudflare-ops`, `security-audit`), not "playground" agents.

## 4. Best Practices

### Naming Conventions

Use suffixes that make intent obvious:
- `_PRODUCTION` / `_PROD` – Production environment
- `_STAGING` / `_STAGE` – Staging environment
- `_DEVELOPMENT` / `_DEV` – Development environment
- `_INTERNAL` – Internal/private instance
- `_EXTERNAL` – External/public instance
- `_WORK` / `_PERSONAL` – Work vs personal identity
- `_SECONDARY` / `_BACKUP` – Secondary/backup account

### Security Isolation

1. **Per-agent configuration** – Only give each agent the accounts it truly needs
2. **Environment separation** – Different tokens per environment (prod / stage / dev)
3. **Least privilege** – Grant minimal scopes to each token
4. **Token rotation** – Rotate regularly, especially production

> ⚠️ **Golden Rule:** Never give production tokens to "exploratory" or "play" agents; only to audited / narrow-scope agents (e.g., `security-audit`, `cloudflare-ops`).

### Example: Multi-Environment Setup

```bash
# .env file
# Production
export CLOUDFLARE_API_TOKEN_PRODUCTION="prod_token"
export CLOUDFLARE_ACCOUNT_ID_PRODUCTION="prod_account_id"

# Staging
export CLOUDFLARE_API_TOKEN_STAGING="staging_token"
export CLOUDFLARE_ACCOUNT_ID_STAGING="staging_account_id"

# Development
export CLOUDFLARE_API_TOKEN_DEVELOPMENT="dev_token"
export CLOUDFLARE_ACCOUNT_ID_DEVELOPMENT="dev_account_id"
```

```jsonc
// opencode.jsonc
"cloudflare_prod": {
  "environment": {
    "CLOUDFLARE_API_TOKEN": "{env:CLOUDFLARE_API_TOKEN_PRODUCTION}",
    "CLOUDFLARE_ACCOUNT_ID": "{env:CLOUDFLARE_ACCOUNT_ID_PRODUCTION}"
  }
},
"cloudflare_staging": {
  "environment": {
    "CLOUDFLARE_API_TOKEN": "{env:CLOUDFLARE_API_TOKEN_STAGING}",
    "CLOUDFLARE_ACCOUNT_ID": "{env:CLOUDFLARE_ACCOUNT_ID_STAGING}"
  }
},
"cloudflare_dev": {
  "environment": {
    "CLOUDFLARE_API_TOKEN": "{env:CLOUDFLARE_API_TOKEN_DEVELOPMENT}",
    "CLOUDFLARE_ACCOUNT_ID": "{env:CLOUDFLARE_ACCOUNT_ID_DEVELOPMENT}"
  }
}
```

## Cursor IDE Integration

### How Cursor Agent Works with Multiple Accounts

Cursor IDE itself uses a single account (your Cursor subscription), but Cursor Agent can access unlimited external service accounts via:

1. **Environment Variables** (loaded from `.env`)
2. **MCP Servers** (configured in `~/.cursor/mcp.json` or project-specific)
3. **Workspace-Specific Config** (each project folder can have different credentials)

### Configuring MCP in Cursor

**File:** `~/.cursor/mcp.json`

```json
{
  "mcpServers": {
    "github_work": {
      "command": "npx",
      "args": ["-y", "@modelcontextprotocol/server-github"],
      "env": {
        "GITHUB_PERSONAL_ACCESS_TOKEN": "ghp_work_token_here"
      }
    },
    "github_personal": {
      "command": "npx",
      "args": ["-y", "@modelcontextprotocol/server-github"],
      "env": {
        "GITHUB_PERSONAL_ACCESS_TOKEN": "ghp_personal_token_here"
      }
    },
    "cloudflare_prod": {
      "command": "npx",
      "args": ["-y", "@modelcontextprotocol/server-cloudflare"],
      "env": {
        "CLOUDFLARE_API_TOKEN": "prod_token",
        "CLOUDFLARE_ACCOUNT_ID": "prod_account_id"
      }
    }
  }
}
```

### Using Multiple Accounts in Cursor

Once configured, Cursor Agent can:

```
# In Cursor chat/command bar:

"Check production Cloudflare for drift"
→ Uses cloudflare_prod MCP

"Search my work GitHub for similar implementations"
→ Uses github_work MCP

"Compare personal and work repos for this pattern"
→ Uses both github_personal and github_work MCPs
```

### Workspace-Specific .env

Each project can have its own `.env`:

```bash
# /Users/sovereign/Desktop/CLOUDFLARE/.env
export CLOUDFLARE_API_TOKEN="client_a_token"
export GITLAB_TOKEN="client_a_gitlab_token"

# /Users/sovereign/Desktop/CLIENT_B/.env
export CLOUDFLARE_API_TOKEN="client_b_token"
export GITLAB_TOKEN="client_b_gitlab_token"
```

Cursor loads the appropriate `.env` when you switch workspaces.

## 5. Usage Examples

### Launching with Multiple Accounts

```bash
# Set tokens before launching
export GITHUB_TOKEN_SECONDARY="ghp_..."
export CLOUDFLARE_API_TOKEN_PRODUCTION="prod_..."

# Launch OpenCode
opencode
/init
```

Inside OpenCode:

```
/use github_secondary
Search for issues in my secondary GitHub account

/use cloudflare_prod
List all zones in the production Cloudflare account
```

### Agent-Specific Access

```bash
/agent cloudflare-ops
# Has: cloudflare_prod, cloudflare_staging, github_secondary

/agent security-audit
# Has: cloudflare_prod only (no staging, no personal GitHub)
```

### Cross-Account Validation

```bash
/agent cloudflare-ops

Compare configuration between production and staging accounts:
1. Query cloudflare_prod for all WAF rules
2. Query cloudflare_staging for all WAF rules
3. Show differences
4. Validate staging matches production baseline
```

## 6. Troubleshooting

### Token Not Working

1. **Verify the environment variable is set:**
   ```bash
   echo "$GITHUB_TOKEN_SECONDARY"
   ```

2. **Check MCP configuration** in `opencode.jsonc`:
   - Variable names match
   - `{env:VARIABLE_NAME}` syntax is correct

3. **Restart OpenCode** after exporting tokens

### MCP Not Loading

1. **Check MCP status** inside OpenCode:
   ```
   /mcp list
   /mcp status github_secondary
   ```

2. **Validate token format:**
   - GitHub: usually `ghp_...`
   - GitLab: usually `glpat_...`

3. **Confirm agent config:**
   - MCP is enabled for that agent in `agents[...].tools`
   - Or globally enabled in `"tools"`

## 7. Security Considerations

### Token Storage

**✅ DO:**
- Store tokens in `.env` (gitignored)
- Use environment variables for credentials
- Rotate tokens every 90 days
- Use separate tokens for prod/staging/dev

**❌ DON'T:**
- Commit tokens to git
- Hardcode tokens in config files
- Share tokens via chat/email
- Use same token across environments

### Audit Trail

Log all multi-account operations:

```bash
# Enable audit logging in .env
export AUDIT_LOG_ENABLED=true
export AUDIT_LOG_PATH="./observatory/audit.log"
```

Operations using multiple accounts will be logged with account identifiers.

### Token Rotation

> 💡 **Future Enhancement:** Could integrate with `playbooks/TUNNEL-ROTATION-PROTOCOL.md` for automated token rotation policies.

## 9. Summary

### To add another account:

1. **Create a unique env var for the token**
   - e.g., `GITHUB_TOKEN_SECONDARY`, `CLOUDFLARE_API_TOKEN_STAGING`

2. **Add an MCP entry in `opencode.jsonc` that uses `{env:...}`**

3. **Enable it per-agent (recommended) or globally**

4. **Keep naming and scopes clear** so you always know which token is doing what

🔐 **Key Point:**  
One account = one env var = one MCP entry.  
From there, agents decide which identities they're allowed to wield.
