What is azure-dev-server CLAUDE.md?

Project instructions for a remote MCP server that gives Claude Desktop filesystem and shell access over HTTP. The server is designed to run on Microsoft Azure, a cloud hosting platform.

Guiding development, formatting, type checks, tests, builds, startup, authentication, and Azure deployment of the remote server.

They document the project structure, commands, architecture, authentication, and tests needed to change and deploy the server safely.

Token cost

What it costs to keep this loaded

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	$0.01749	$0.01749
Opus 5.5	$0.00700	$0.00700
Sonnet 5.5	$0.00350	$0.00350
Haiku 4.5	$0.00175	$0.00175

Security

Grade A, and why

azure-dev-server 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 2mo 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.

Project overview

Remote MCP server that exposes filesystem and shell access over Streamable HTTP transport. A cloud-hosted Desktop Commander for Claude Desktop. Designed to run on Azure (Container Apps or Functions) so Claude Desktop can read, write, build, and test on a remote machine.

Build & test commands

pnpm run build          # TypeScript → dist/
pnpm run lint           # ESLint strict checks
pnpm run format:check   # Prettier formatting check
pnpm run format         # Auto-format all files
pnpm run type-check     # TypeScript type checking
pnpm run test           # Node.js built-in test runner (25 tests, 8 suites)
pnpm run check          # All of the above in sequence
pnpm run start          # Run compiled server (dist/server.js)

Architecture

src/
  server.ts   → How does the HTTP server start and route requests?
  tools.ts    → What tools can Claude Desktop use remotely?
  fs-ops.ts   → How are filesystem read and search operations implemented?
  auth.ts     → How are requests authenticated?
  types.ts    → What shapes exist?

tests/
  server.test.mjs   → Does the HTTP server start and respond correctly?
  tools.test.mjs    → Do the phase-2 tools (edit_file, search_files) behave correctly?
  fs-ops.test.mjs   → Do the filesystem read and search operations work correctly?

Dockerfile        → Multi-stage build: builder (compile) → runner (prod deps + dist/)
docker-compose.yml → Local testing with /workspace volume mount
.dockerignore     → Excludes node_modules, dist, .git, tests from build context

Each source file answers ONE question. No file has two jobs.

Source is TypeScript (strict mode). Compiled to dist/ via pnpm run build. Tests import from dist/. Entry point: dist/server.js.

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.
