description	Manage Cloudflare DNS zones, Workers, Pages, R2, KV, D1, and analytics via REST API. Use when the user wants to query DNS, deploy a Worker, list R2 buckets, manage KV namespaces, run D1 queries, or check analytics without the Cloudflare MCP installed.

Cloudflare

Direct REST access to Cloudflare's control plane — DNS, Workers, Pages, R2, KV, D1. Use when needing the current account state or one-off mutations without wrangler.

Usage

• Use for: DNS record CRUD, listing/inspecting Workers/KV/R2/D1/Pages, running D1 queries, deploying small Workers.
• Skip for: Worker bundling / TS / local dev (use wrangler), bulk R2 object uploads (use S3 client), billing questions.

Credentials check

[ -n "$CLOUDFLARE_API_TOKEN" ] && echo "CLOUDFLARE_API_TOKEN: PRESENT" || echo "CLOUDFLARE_API_TOKEN: MISSING"

Never echo the variable directly.

If MISSING, respond to the user with EXACTLY this message (do NOT paraphrase, do NOT suggest manual JSON edits):

I need your cloudflare credential. Run this in another terminal — it'll open the signup page, validate format, and save it safely with masked input:

teleport-setup add-key cloudflare

Then restart Claude Code (/exit, then claude) and ask me again.

Do NOT suggest editing ~/.claude/settings.local.json manually. The teleport-setup add-key command handles it with backup, validation, and masked input. Stop execution until the user has run the command and restarted.

API

• Base URL: https://api.cloudflare.com/client/v4
• Auth: Authorization: Bearer $CLOUDFLARE_API_TOKEN — scoped API Token only, never the legacy Global API Key (X-Auth-Email + X-Auth-Key). Verify with GET /user/tokens/verify.
• Response envelope (every response): {"success": bool, "errors": [...], "messages": [...], "result": ...}. Always check .success before reading .result — jumping straight to .result.X silently hides failures.
• Prerequisites: endpoints need either Account ID (Workers, KV, R2, D1, Pages) or Zone ID (DNS, rulesets, WAF). Both are 32 hex chars; not interchangeable. Fetch via GET /accounts and GET /zones?name=example.com.
• Rate limits: 1,200 req / 5 min cumulative per user across dashboard + tokens, plus 200 req/s per IP. Respect Retry-After on 429.

Entity hierarchy

account → { zones → dns_records } ∪ workers/scripts ∪ storage/kv/namespaces (+ keys/values) ∪ r2/buckets (objects on separate S3 host) ∪ d1/database (+ query) ∪ pages/projects (+ deployments).

Endpoints

Resource	Method · Path
Zones	GET /zones?name=example.com
DNS records	GET/POST /zones/{zone_id}/dns_records, PATCH/DELETE .../{record_id}
Workers scripts	GET /accounts/{account_id}/workers/scripts, PUT .../{script_name} (multipart)
KV namespaces	GET /accounts/{account_id}/storage/kv/namespaces
KV values / keys	PUT/GET .../namespaces/{ns}/values/{key}, GET .../namespaces/{ns}/keys
R2 buckets	GET /accounts/{account_id}/r2/buckets (objects → S3 host, see below)
D1 databases / query	GET/POST /accounts/{account_id}/d1/database[/{db_id}/query]
Pages	GET/POST /accounts/{account_id}/pages/projects[/{project}/deployments]
Zone analytics	GET /zones/{zone_id}/analytics/dashboard

Primary workflow — DNS records

# 1. Zone ID by domain
ZONE_ID=$(curl -sL -H "Authorization: Bearer $CLOUDFLARE_API_TOKEN" \
  "https://api.cloudflare.com/client/v4/zones?name=example.com" | jq -r '.result[0].id')

# 2. List A records for a name
curl -sL -H "Authorization: Bearer $CLOUDFLARE_API_TOKEN" \
  "https://api.cloudflare.com/client/v4/zones/$ZONE_ID/dns_records?type=A&name=api.example.com" \
  | jq '.result[] | {id, name, content, ttl, proxied}'

# 3. Create a record
curl -sL -X POST -H "Authorization: Bearer $CLOUDFLARE_API_TOKEN" -H "Content-Type: application/json" \
  "https://api.cloudflare.com/client/v4/zones/$ZONE_ID/dns_records" \
  -d '{"type":"A","name":"api.example.com","content":"1.2.3.4","ttl":300,"proxied":true}'

Secondary workflows

D1 — execute SQL with positional params:

curl -sL -X POST -H "Authorization: Bearer $CLOUDFLARE_API_TOKEN" -H "Content-Type: application/json" \
  "https://api.cloudflare.com/client/v4/accounts/$ACCOUNT_ID/d1/database/$DB_UUID/query" \
  -d '{"sql":"SELECT id, email FROM users WHERE created_at > ?1 LIMIT 10","params":["2026-01-01"]}' \
  | jq '.result[0].results'

KV — raw value bodies, not JSON. Reads return the raw value, not the envelope:

curl -sL -X PUT -H "Authorization: Bearer $CLOUDFLARE_API_TOKEN" \
  "https://api.cloudflare.com/client/v4/accounts/$ACCOUNT_ID/storage/kv/namespaces/$NS/values/flag" --data "on"
curl -sL -H "Authorization: Bearer $CLOUDFLARE_API_TOKEN" \
  "https://api.cloudflare.com/client/v4/accounts/$ACCOUNT_ID/storage/kv/namespaces/$NS/values/flag"

R2 — buckets via main API; objects via S3-compatible host https://{account_id}.r2.cloudflarestorage.com/{bucket}/{key}. Authenticate with SigV4 using R2 access keys (generated under R2 → Manage API tokens, separate from the API token). Any S3 SDK works.

Gotchas

• Always check .success. Pattern: jq 'if .success then .result else .errors end'. Silent failures otherwise.
• R2 objects are NOT on the main API. Bucket CRUD is, but object PUT/GET/DELETE use https://{account_id}.r2.cloudflarestorage.com with S3 SigV4 and separate R2 access keys — not the API token.
• Token scope mismatch → 403 with no introspection. Zone:Read can't edit DNS; Workers:Edit can't touch KV. /user/tokens/verify only confirms the token is live, not which scopes it holds. On 403, assume missing scope first.
• Account ID vs. Zone ID. Zone URLs reject account IDs and vice versa (404 / error 1001). Both are 32 hex chars, easy to swap.
• ttl: 1 means Auto, not one second. Explicit TTLs: 60–86400.
• KV is eventually consistent. Writes can take up to ~60s to propagate globally. Don't assume read-after-write on a different edge.
• Page Rules → Rulesets. Legacy /zones/{id}/pagerules is deprecated; target /zones/{id}/rulesets for new work. Several WAF / firewall endpoints migrated similarly.
• Rich analytics live in GraphQL at /client/v4/graphql with its own query cost model; the REST analytics/dashboard endpoint is coarser.
