## Scores

| Criterion | Score | Evidence |
|-----------|-------|----------|
| Token Efficiency | 7/10 | Fastly's API likely supports field selection and pagination based on industry standards for CDN/edge compute platforms, though specific query optimization features are not evident from available signals. |
| Programmatic Access | 8/10 | Fastly offers multiple strong access methods including REST API, official SDKs in Node.js and Python, a feature-rich CLI, and Infrastructure-as-Code support via Pulumi, providing excellent programmatic coverage. |
| Autonomous Auth | 8/10 | Fastly supports API key authentication which enables autonomous agent access without OAuth friction, though no explicit evidence of scoped/granular permissions is visible in collected signals. |
| Speed & Throughput | 7/10 | As an edge computing platform, Fastly is architected for low latency, and the extensive CLI and SDK support suggest efficient request patterns, though specific rate limit details and concurrent request handling are not documented in signals. |
| Discoverability | 6/10 | Fastly has comprehensive developer documentation and a CLI with help systems, but lacks an OpenAPI specification (not found), which limits automated client generation and discoverability for agents. |
| Reliability | 7/10 | As a mature enterprise platform, Fastly likely implements API versioning and consistent schemas (evidenced by long-lived SDK versions and API client libraries), though explicit idempotency and versioning details are not confirmed in signals. |
| Safety | 6/10 | Fastly's edge compute and infrastructure-as-code support (Pulumi) suggest test/staging environments are available, but no explicit dry-run, undo, or sandbox mode indicators are present in the collected signals. |
| Reactivity | 5/10 | No evidence of webhooks, streaming, or SSE capabilities in collected signals; agents would likely need to rely on polling for reactive patterns, which is less efficient than event-driven alternatives. |

## Biggest Friction

Absence of an OpenAPI specification combined with no MCP server support limits automated agent discoverability and integration, requiring manual API exploration and custom integration code.

## Access Methods

- REST API
- CLI
- SDKs: Node (@fastly/js-compute), Python (fastly)

## Auth

Methods: unknown. Human required: Yes. Scoped permissions: No.
