Available tools
| Tool group | Tools | Purpose |
|---|---|---|
| Zone inventory | list_zones, get_zone, get_zone_settings | Inspect available zones and key settings |
| DNS records | list_dns_records, get_dns_record, create_dns_record, update_dns_record, delete_dns_record | Read and mutate records |
| Edge actions | purge_cache, list_page_rules | Invalidate cached content and inspect page rules |
delete_dns_record and full-cache actions stay gated behind the destructive env flags described in
docs/start-here.md.
Runtime proof
| Claim | Proof |
|---|---|
| Package entry point is stable | mcp-cloudflare-dns = "cf.server:main" in pyproject.toml |
| Server is MCP-specific, not a generic CLI | FastMCP("mcp-cloudflare-dns") in cf/server.py |
| Cloudflare failures are retried | _call() in cf/server.py |
| Release artifacts are built | dist/ wheel and tarball are checked into the repo |
Repo map
| Path | Purpose |
|---|---|
cf/server.py | FastMCP tool surface, env loading, retry wrapper |
pyproject.toml | Package metadata, version, script entry point |
