Scoping an agent key

Every agent key carries a set of scopes. A scope is a capability grant — read tokens, execute trades, read positions, deliver notifications. The server enforces scopes on every tool call and API endpoint; a call outside the granted scope fails with a structured authorization error.

Best practice: grant the minimum scopes the agent key actually needs

This is the single most important rule for agent-key scoping. For every agent key, grant only the scopes the integration actively uses — nothing speculative, nothing "just in case," nothing broader than the job requires.

Concretely:

• Start from what the integration does on its hot path, and enumerate only those capabilities.
• When in doubt, grant less and widen later if the integration errors on a missing scope.
• Create a separate agent key per integration (or per purpose) rather than one fat key reused everywhere — that way each key's scope surface stays tight.
• If a scope is required for a one-off setup step but not for steady-state operation, consider doing the setup with a broader key and then running with a narrower one.

Broader scopes are a liability: a leaked key is only as dangerous as the capabilities it carries.

Principles

• Separate read from write. Read scopes are generally safe; write/execute scopes move money or send messages and deserve more scrutiny.
• Per-integration, not per-user-role. A scope is a capability, not a persona. Reason about what the integration does, not who the user is.

Scope categories

Authoritative scope names live in the docs; these are the categories to reason about:

• Read scopes — querying token info, positions, wallet balances, alpha signals. Safe for analytics and display use cases.
• Trading scopes — planning trades, executing trades, cancelling orders. Required for any integration that moves funds.
• Delivery scopes — sending notifications (Telegram, email) on behalf of the user. Rate-limited.
• Administrative scopes — managing the user's agent keys themselves, linked wallets, etc. Typically not needed by third-party integrations.

Fetch https://docs.shuriken.trade/llms.txt for the current authoritative scope list and the exact names to pass when minting a key.

Common scope combinations

• Read-only analytics dashboard: read scopes only.
• Automated trading bot: read scopes + trading scopes.
• Notification/alert service: read scopes + delivery scopes.
• Full-service trading + notifications: read scopes + trading scopes + delivery scopes.

When a call fails on scope

The error response names the missing scope. Two valid responses:

1. If the scope is genuinely needed, guide the user to rotate the key with the added scope.
2. If the scope should not be needed (the call is read-only but erroring on a write scope), something in the integration is calling the wrong endpoint — investigate before granting.

Pointers

• Platform documentation (including scope reference): fetch https://docs.shuriken.trade/llms.txt and search for "scopes"
