The two tools have clearly distinct purposes: one saves visualization JSON to a local file, the other pushes it to an API. There is no overlap in their primary functions, so an agent can easily choose the correct one based on the desired destination.

Both tool names use snake_case and start with imperative verbs (export, push). The pattern differs slightly—'export_json' is verb + object, while 'push_to_navigate' includes a preposition—but they remain readable and follow a similar style.

With only two tools, the set feels thin for a general visualization server. However, for the narrow scope of exporting and pushing visualizations, the count is borderline acceptable rather than clearly insufficient.

The tools cover the two primary output paths (local save and remote API push), which covers the core workflow. Minor gaps exist, such as no listing or deletion of saved visualizations, but these are not dead ends for the main use case.
