Operate and inspect your CDN account via conversation

Fastly's official MCP server wraps the Fastly API so an MCP client can inspect and operate a CDN account through conversation. It exposes the objects that make up a Fastly configuration: services and their versioned configs, domains, backends and origins, access control lists and edge dictionaries, plus cache operations such as purging by URL, by surrogate key, or across an entire service. On the read side it returns traffic and cache statistics, both historical and real time, so an agent can answer questions about cache hit ratio, bandwidth by region, or error rates without anyone opening the control panel. Write access is bounded by the Fastly API token the server runs with, which is the practical safety control here: teams typically issue a read-only token for investigation and troubleshooting work, and a separate scoped token when they want an agent to actually change configuration. It ships as open source and runs locally as a CLI process, so it installs into Claude Code, Cursor, Claude Desktop or any other MCP client without a hosted intermediary holding credentials. Built for platform, edge and SRE engineers who spend time diagnosing delivery problems, checking whether a purge landed, or confirming which service version is live.
