How Spaceship could raise this score

The criteria with the most room to improve, lowest first. Each pairs the gap we observed with the capability that criterion rewards. These are improvement priorities, not predictions — implementing them is what would move the score in a future revision.

Agent-interface readiness

2.5/10 · 12% weight

Today: No official MCP or capability manifest; no machine-readable pricing.

To improve

  • Ship an official MCP (or A2A) interface that an agent can call directly.
  • Publish machine-readable pricing and machine-readable policies.
  • Provide a capability manifest an agent can read before acting.

Agent safety

3/10 · 12% weight

Today: 2FA; no audit-log API, approval flow, spend limit, or rollback.

To improve

  • Add per-token or per-agent spend limits so a delegated agent cannot overspend.
  • Offer human-approval flows (webhooks/confirmations) for high-risk actions like transfers.
  • Provide audit logs, change history, and a rollback window for registrations and transfers.

Authentication & delegation

4/10 · 14% weight

Today: X-API-Key + X-API-Secret headers; no OAuth, no scoped tokens.

To improve

  • Issue scoped, least-privilege API tokens instead of all-or-nothing account keys.
  • Make credentials revocable and short-lived (expiring tokens, key rotation).
  • Support delegating limited access to an agent without sharing full account control.

Where Spaceship is already strong: Pricing transparency (8/10).
