Decide Whether the Agent Acts for a User or for Itself<\/strong><\/h4>\n<p><span data-contrast=\"auto\">These are different identity models.<\/span><span data-ccp-props=\"{&quot;134233117&quot;:false,&quot;134233118&quot;:false,&quot;335551550&quot;:0,&quot;335551620&quot;:0,&quot;335559738&quot;:240,&quot;335559739&quot;:240}\">\u00a0<\/span><\/p>\n<p>A delegated agent acts on behalf of a particular person. An autonomous agent performs a defined workload under its own identity. Snowflake\u2019s current agent-identity documentation distinguishes these models and supports agent-aware identification through managed entry points and appropriately configured OAuth integrations.<\/p>\n<p>For an employee-facing assistant, preserve the requesting user\u2019s identity and apply application authorization before invoking tools. A shared, broadly privileged backend account should not become a shortcut around employee-level restrictions.<\/p>\n<p>For an autonomous workflow, create a dedicated identity with only the workload\u2019s required access. Snowflake documents the SERVICE_AGENT user type for automated AI agents operating under their own identity and privileges. It supports non-interactive authentication methods, including workload identity federation, key-pair authentication, and programmatic access tokens. Confirm support in the chosen client and endpoint.<\/p>\n<p>For customer-facing applications, resolve tenant and customer authorization from the authenticated application session. Do not let the model supply an unrestricted tenant identifier and treat it as proof of access.<\/p>\n<p><b><span data-contrast=\"auto\">Identity should come from a trusted authentication path, not from the prompt.<\/span><\/b><\/p>\n<h4><strong>2. Restrict the Session, Not Just the Default Role<\/strong><\/h4>\n<p><span data-contrast=\"auto\">For a narrowly scoped Snowflake OAuth integration, use an explicit role allowlist and disable unnecessary secondary-role activation.<\/span><span data-ccp-props=\"{&quot;134233117&quot;:false,&quot;134233118&quot;:false,&quot;335551550&quot;:0,&quot;335551620&quot;:0,&quot;335559738&quot;:240,&quot;335559739&quot;:240}\">\u00a0<\/span><\/p>\n<p><span data-contrast=\"auto\">Relevant Snowflake OAuth settings include <\/span><span data-contrast=\"auto\">ALLOWED_ROLES_LIST<\/span><span data-contrast=\"auto\"> and <\/span><span data-contrast=\"auto\">OAUTH_USE_SECONDARY_ROLES = NONE<\/span><span data-contrast=\"auto\">. The documentation specifies that the allowlist cannot be combined with <\/span><span data-contrast=\"auto\">OAUTH_USE_SECONDARY_ROLES = IMPLICIT<\/span><span data-contrast=\"auto\">. Keep role switching disabled unless the workflow genuinely requires it. External OAuth has its own configuration, so do not assume identical settings apply. <\/span><span data-ccp-props=\"{&quot;134233117&quot;:false,&quot;134233118&quot;:false,&quot;335551550&quot;:0,&quot;335551620&quot;:0,&quot;335559738&quot;:240,&quot;335559739&quot;:240}\">\u00a0<\/span><\/p>\n<p><span data-contrast=\"auto\">Also verify what the MCP client actually requests. Some clients use a scope that results in the user\u2019s default role rather than the role the team expected. <\/span><span data-ccp-props=\"{&quot;134233117&quot;:false,&quot;134233118&quot;:false,&quot;335551550&quot;:0,&quot;335551620&quot;:0,&quot;335559738&quot;:240,&quot;335559739&quot;:240}\">\u00a0<\/span><\/p>\n<p><span data-contrast=\"auto\">For a connector-based integration, a startup statement such as <\/span><span data-contrast=\"auto\">USE SECONDARY ROLES NONE<\/span><span data-contrast=\"auto\"> can establish an initial session state. It is not a complete boundary if the identity can subsequently activate broader roles. Restrict the underlying grants and permitted session behavior.<\/span><\/p>\n<h4><strong>3.

Can I connect an AI agent to Snowflake using my existing account?\u00a0<\/strong><\/h4>\n<p>Technically, an integration can use a human identity, but its effective session must be deliberately restricted. Do not assume selecting a lower-privilege role removes access inherited through other active roles. For user-facing workflows, use a controlled delegated connection. For autonomous workloads, prefer a dedicated agent identity with workload-specific permissions.<\/p>\n<h4><strong>Q. Is a read-only Snowflake role enough to prevent data leakage?\u00a0<\/strong><\/h4>\n<p>No. Read-only access addresses modification, not whether the identity can read too much. Retrieval services and owner\u2019s-rights programs also require separate review. Limit exposed data, enforce user authorization, and test what reaches the tool result and model context, not only the final answer.<\/p>\n<h4><strong>Q. Does access to a Snowflake MCP server automatically grant access to its tools?\u00a0<\/strong><\/h4>\n<p>No. The server and referenced tools have separate access requirements. Depending on the tool, permissions may include access to a Cortex Search service, a semantic view, a Cortex Agent, or a function or stored procedure. Provision only the resources the workflow needs.<\/p>\n<h4><strong>Q. How do I stop an AI agent from inheriting secondary roles?\u00a0<\/strong><\/h4>\n<p>Use controls appropriate to the authentication path. Snowflake OAuth supports restricting permitted roles and secondary-role behavior. A role-restricted PAT does not use secondary roles. For connector sessions, disabling secondary roles at startup is only one layer; also restrict the identity\u2019s grants and ability to activate broader access.<\/p>\n<h4><strong>Q. Does Cortex AI Gateway replace Snowflake RBAC or MCP authorization?\u00a0<\/strong><\/h4>\n<p>No. Cortex AI Gateway governs inference traffic routed through it. It does not grant database privileges or replace tool authorization. Gateway access also does not remove the need for the underlying model permissions. Design and test inference governance separately from data access.<\/p>\n<\/div>\n\n","protected":false},"excerpt":{"rendered":"<p>Your team wants an AI agent to explain revenue changes, investigate support issues, or summarize operational exceptions using Snowflake data.\u00a0 The connection works.
