modbender AgentKeys Skill
Secure credential proxy for AI agents. Route API calls through AgentKeys so your agent never sees real secrets.
Configuration
You have two options. Set these in your environment or .env:
Option A — API Key (recommended, multi-credential)
AGENTKEYS_API_KEY=ak_ws_...
AGENTKEYS_PROXY_URL=https://proxy.agentkeys.io
Use your workspace API key to proxy requests to any credential by name. Get your API key from Settings.
Option B — Direct Proxy Token (single credential)
AGENTKEYS_PROXY_TOKEN=pxr_...
AGENTKEYS_PROXY_URL=https://proxy.agentkeys.io
Use a proxy token for one specific credential. Get it by assigning a credential to an agent in the dashboard.
Usage
With API Key (Option A) — reference credentials by name
curl -X POST $AGENTKEYS_PROXY_URL/v1/proxy \
-H "Authorization: Bearer $AGENTKEYS_API_KEY" \
-H "X-Credential-Name: resend" \
-H "X-Target-Url: https://api.resend.com/emails" \
-H "Content-Type: application/json" \
-d '{"from": "noreply@example.com", "to": "user@example.com", "subject": "Hello", "text": "Sent via AgentKeys"}'
With Proxy Token (Option B) — direct credential access
curl -X POST $AGENTKEYS_PROXY_URL/v1/proxy \
-H "Authorization: Bearer $AGENTKEYS_PROXY_TOKEN" \
-H "X-Target-Url: https://api.resend.com/emails" \
-H "Content-Type: application/json" \
-d '{"from": "noreply@example.com", "to": "user@example.com", "subject": "Hello", "text": "Sent via AgentKeys"}'
Headers
| Header | Required | Description |
|---|---|---|
Authorization |
✅ | Bearer $AGENTKEYS_API_KEY or Bearer $AGENTKEYS_PROXY_TOKEN |
X-Target-Url |
✅ | Target API URL to forward to |
X-Credential-Name |
✅ (API key mode) | Name of the credential to use (case-insensitive) |
Content-Type |
❌ | Passed through to target |
How It Works
- Agent sends request to AgentKeys proxy with API key + credential name (or proxy token)
- AgentKeys finds and decrypts the real credential server-side
- Real credential is injected into headers
- Request is forwarded to the target API
- Response is returned to the agent
- Every request is logged in the audit trail
The agent never sees the real API key, OAuth token, or password.
Credential Types Supported
- API Key — injected as
Authorization: Bearer <key> - Basic Auth — injected as
Authorization: Basic base64(user:pass) - Custom Headers — injected as key-value pairs
- Query Parameters — appended to URL
- Cookies — injected as
Cookieheader - OAuth — auto-refreshed tokens
Security
- Credentials are AES-256-GCM encrypted at rest
- Proxy tokens are scoped to one credential + one agent
- API key mode still respects workspace permissions
- Tokens can be revoked instantly from the dashboard
- Full audit trail for every proxied request
- Agent never has access to plaintext secrets
