Claimable Postgres

The claimable-postgres skill enables AI agents to securely manage database access through a claim-based authentication model. It allows agents to request temporary, scoped permissions for PostgreSQL instances without requiring long-lived credentials or direct API key exposure. This approach ensures that database interactions remain auditable and revocable based on specific agent needs.

When to use it

• Granting an AI agent temporary read-only access to a development database for automated testing workflows.
• Allowing a data analysis agent to query production metrics with strict row-level security constraints.
• Enabling secure handoff of database tasks between multiple agents without sharing master credentials.
• Implementing zero-trust principles where agents must "claim" specific scopes before executing SQL commands.

Key capabilities

• Claim-based authentication: Agents request access tokens based on defined scopes rather than using static keys.
• Scoped permissions: Access is limited to specific databases, schemas, or operations (e.g., SELECT only).
• Automatic token generation: The system issues short-lived credentials upon successful claim validation.
• Audit trail: Every claimed access request and subsequent database operation is logged for security review.

Example prompts

• "Claim read-only access to the analytics schema in my PostgreSQL instance so I can generate weekly sales reports."
• "Request a temporary token with INSERT permissions on the users table to sync data from our CRM system."
• "Verify if I have claimed write access to the inventory database and list any active sessions for that scope."

Tips & gotchas

Ensure your PostgreSQL instance is configured with the necessary OIDC or claim verification endpoints before attempting to use this skill. Remember that claims are temporary; agents must re-authenticate or refresh their tokens if the session expires during long-running tasks.
