Fastly Agent Toolkit

Fastly Agent Toolkit gives Claude working knowledge of the Fastly CDN platform and the Fastly Agent Toolkit GitHub repo. It reads and writes VCL snippets, runs the VCL linter, builds and runs Compute@Edge projects locally, and maps service versions to active configurations. You get six focused tools that cover code authoring, linting, local Compute execution, service management, cache/security rules, and deployment via the Fastly CLI and API.

It opens and edits VCL files, checks them for syntax and best-practice issues, and suggests specific fixes. It runs your Compute app locally, watches console output, and helps you iterate by rebuilding and reloading the local runtime. For services it pulls service lists, inspects active backends and dictionaries, and creates or clones service versions.

For delivery and ops it checks and updates caching rules, manages ACLs and TLS settings, and posts deploy commands through the CLI or API. It pulls real-time logs and metrics when available, and it records deployment IDs and version numbers so you can track rollbacks and audits.

Imagine editing VCL, testing a Compute worker, and deploying a version without leaving your terminal or switching between the Fastly docs, CLI, and a separate editor. That flow saves time when you need to fix a cache rule, verify logs, and push a hotfix during a production incident.
