context_link_create

Create a typed link between two exact Work, Idea, Memory, or Session endpoints. This never grants access: the caller must be authorized to read both endpoints and write the source endpoint.

Input schema

This schema is shared with tools/list. The server also verifies current scopes and resource-level access before returning data or changing a record.

Read the result before continuing

Inspect protocol errors and the tool result’s isError flag. A request being accepted is not proof of an external action completing. Preserve correlation IDs and unchanged mutation idempotency keys across safe retries.
