What is spotify-mcp-server CLAUDE.md?

Project-specific instructions for Claude Code sessions working on a Spotify playlist server and its companion website.

Setting up the project, running tests and builds, finding code by area, and following rules for Spotify API responses, authentication, and sensitive tokens.

They give the coding agent the project layout, commands, security rules, and data-handling requirements it needs to make safe changes.

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	$0.00493	$0.00493
Opus 5.5	$0.00197	$0.00197
Sonnet 5.5	$0.00099	$0.00099
Haiku 4.5	$0.00049	$0.00049

Measured 2mo ago against content hash 5a41625950b8, method: parsed. Prices are Anthropic first-party input rates as of 2026-10-07, from the pricing page.

Security

Grade A, and why

spotify-mcp-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

Spotify MCP Server — lets Claude create Spotify playlists through natural language. Website at playmcp.dev (Astro 6, Cloudflare Pages).

Commands

npm run build        # Compile TypeScript
npm test             # Run 99 tests (vitest)
npm run dev          # TypeScript watch mode
cd website && npm run build  # Build Astro site

Architecture

├── spotify/       # API client, search, playlists, playlist-items
├── tools/         # MCP tool registration + Zod schemas
├── prompts/       # Creative playlist prompt templates

Rules

Security first. Defense in depth on everything. Validate inputs, sanitize outputs, never leak tokens in errors.
No Spotify data caching. API responses are ephemeral — never persist beyond the current request. This is a compliance requirement.
All API responses must go through safeParseJsonResponse. Never use raw response.json().
All string inputs must use the safeString Zod refinement. Rejects null bytes and control characters.
Test everything. New features need tests. Currently at 99 tests across 9 files.
Pin GitHub Actions to SHA hashes. Never use version tags like @v4.
Internal docs are gitignored. TODO.md, WEBAPP_PLAN.md, RESEARCH_PROMPTS.md, OUTREACH_DRAFTS.md never get committed.
Node 20+ required. Vitest 4 needs it.
Commit messages should be descriptive. Include what changed and why.
Don't add features without asking. Keep changes focused on what was requested.

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.
