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 | $0.00899 | $0.00899 |
| Opus 5 | $0.00449 | $0.00449 |
| Sonnet 5 | $0.00180 | $0.00180 |
| Haiku 4.5 | $0.00090 | $0.00090 |
Grade A, and why
licensespring-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 11d 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
LicenseSpring MCP Server - An MCP (Model Context Protocol) server implementation that integrates with LicenseSpring APIs for license management and customer operations. The project provides two separate MCP servers: License API server and Management API server.
Development Commands
Build and Development
npm run build # Compile TypeScript to JavaScript
npm run dev # Start in development mode (shows usage help)
npm run lint # Run ESLint on TypeScript files
npm run lint:fix # Auto-fix ESLint issues
npm test # Run unit tests with Jest
npm run test:integration # Run comprehensive integration tests against real API
Running Servers
npm run license-api # Start License API MCP server
npm run management-api # Start Management API MCP server
Release Commands
npm run release # Patch release (1.0.0 -> 1.0.1)
npm run release:minor # Minor release (1.0.0 -> 1.1.0)
npm run release:major # Major release (1.0.0 -> 2.0.0)
npm run version:dry # Preview version bump without changes
npm run publish:dry # Preview NPM publish without publishing
Architecture
Project Structure
- src/index.ts: Main entry point that routes to appropriate server
- src/license-api-server.ts: License API MCP server implementation with 19 tools
- src/management-api-server.ts: Management API MCP server with 15 tools
- src/utils/auth.ts: Authentication validation and HMAC signature generation
- src/utils/http.ts: HTTP client implementations for both APIs with error handling
- src/types/index.ts: TypeScript type definitions for API responses
Authentication Flow
- Primary: LICENSE_API_KEY for License API, MANAGEMENT_API_KEY for Management API
- Optional: LICENSE_SHARED_KEY for enhanced HMAC authentication (License API only)
- The server validates credentials on startup and provides tier-appropriate functionality
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.
