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 | $0.00296 | $0.00296 |
| Opus 5 | $0.00148 | $0.00148 |
| Sonnet 5 | $0.00059 | $0.00059 |
| Haiku 4.5 | $0.00030 | $0.00030 |
Grade A, and why
contentful-mcp-graphql 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 9d 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.
This is a copy
100% identical to mcp-picnic CLAUDE.md — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
What it actually says
Contentful GraphQL MCP - Development Guide
Common Commands
- Build:
npm run build - Type Check:
npm run typecheck - Lint:
npm run lint - Run Tests:
npm test - Run Single Test:
npx vitest run test/path/to/test.test.ts - Run Tests in Watch Mode:
npm run test:watch - Dev Mode (watch & rebuild):
npm run dev
Code Style Guidelines
- Formatting: Uses Prettier with 100 char width, no semicolons, double quotes
- TypeScript: Use strict typing, avoid
anywhen possible - Imports: Order from external to internal, group related imports
- Naming: Use camelCase for variables/functions, PascalCase for types/interfaces
- Error Handling: Always handle errors in async functions with try/catch blocks
- Documentation: Add JSDoc style comments for functions and interfaces
Entity Structure
- Each handler should focus on a single responsibility
Testing
Tests use Vitest with a lightweight unit testing approach. Current test structure:
test/unit/- Lightweight unit tests for public API functions
Focus on testing behavior, not implementation details. See test/README.md for detailed testing guidelines.
Context
This is a MCP Server that enables LLM's to connect to Contentful GraphQL Endpoint.
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.
