Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.01303 | $0.01303 |
| Opus 5 | $0.00651 | $0.00651 |
| Sonnet 5 | $0.00261 | $0.00261 |
| Haiku 4.5 | $0.00130 | $0.00130 |
Grade A, and why
cloudflare-workers-mcp CLAUDE.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 10d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 127 lines — stays where its author put it; the contents beside it link to each section on GitHub.
CLAUDE.md
This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
Overview
This is an MCP (Model Context Protocol) server for managing Cloudflare Workers: deploying static sites and Worker scripts, and managing versions, deployments, custom domains, and cron triggers. It connects via stdio transport for use with Claude Desktop and Claude Code.
Project status: feature-complete v1. All six milestones (M1–M6) are
implemented — 22 tools covering static-site deploys (the headline feature),
script lifecycle, versions/deployments/rollback, domains/subdomain/cron, and
log queries. Read IMPLEMENTATION_PLAN.md before changing API-facing
code — it carries verified API endpoint documentation (including the
static-asset direct-upload protocol) and the design gotchas; all endpoint
facts were re-verified against live Cloudflare docs on 2026-07-13.
This repo is the successor to
cloudflare-pages-mcp
(local: ~/workspace/personal/cloudflare-pages-mcp, now in maintenance mode).
The architecture deliberately mirrors it — when in doubt about a pattern
(summarizers, error suggestions, live-test guarding), the pages repo is the
worked example with 21 tools.
Commands
# Install dependencies
npm install
# Build (compile TypeScript to dist/)
npm run build
# Development mode with watch
npm run dev
# Type checking only (no emit)
npm run typecheck
# Run the server
npm start
# Tests (Node's built-in test runner via tsx — no extra framework)
npm test # unit + protocol smoke (safe, no creds, CI-ready)
npm run test:unit # pure-logic units, fully mocked fetch
npm run test:protocol # builds, then drives the real server over the MCP stdio wire
npm run test:live # guarded live e2e: deploys/serves/deletes a throwaway cf-mcp-test-* site
npm run typecheck:test # type-check the test files too (tsconfig.test.json)
See test/README.md for the test layering.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
