API KEY
MEETING NOTES
Every meeting recording, highlight clip, and transcript your team captures lives in Grain. Grain MCP gives your agent authenticated access to meeting intelligence scoped to the user who authorized it.

scope → enforced ✓Does the agent access Grain MCP as the user or as a shared key?
As the user. Each workspace member authorizes once and Scalekit resolves their credential at request time. Audit logs attribute every action to that user, not a shared service account.
Where is the Grain MCP api key stored?
In Scalekit's managed AES-256 token vault, namespaced per tenant. Refresh is automatic. Revocation is a single dashboard action. Tokens never appear in prompts, logs, or LLM context.
Can I limit what the agent is allowed to do in Grain MCP?
Yes. Pass a tool name filter to listScopedTools so the meeting intelligence agent only sees the subset you authorize. Pre-API-call scope checks block out-of-policy actions before the request reaches Grain MCP.
What happens when a user revokes Grain MCP access?
The connection is invalidated on the next tool call. Subsequent requests for that user fail closed with a clear error. Other users in the tenant remain unaffected. The event is logged for audit.
Can the agent access private recordings from other team members?
Only recordings the authorizing user owns or has been explicitly shared on. Grain workspace visibility rules apply. Private recordings from other team members stay inaccessible.
