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 | $0.08132 | $0.08132 |
| Opus 5 | $0.04066 | $0.04066 |
| Sonnet 5 | $0.01626 | $0.01626 |
| Haiku 4.5 | $0.00813 | $0.00813 |
Grade A, and why
mcp-gateway 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.

MCP Gateway - Claude Development Guide
Project Overview
The MCP Gateway is a production-ready API gateway for Model Context Protocol (MCP) servers, providing enterprise-grade infrastructure with authentication, logging, rate limiting, server discovery, and multi-protocol transport support.
Core Purpose
- Enterprise Infrastructure: JWT authentication, RBAC, and flexible policies
- Multi-Protocol Support: JSON-RPC, WebSocket, SSE, HTTP, and STDIO transports
- Service Virtualization: Wrap REST/GraphQL/gRPC services as virtual MCP servers
- Production Ready: Comprehensive logging, IP rate limiting with Redis/memory backends, and health monitoring
- Namespace Management: Group MCP servers into logical namespaces within an organization
- Developer Tools: MCP Inspector for real-time debugging and testing
Key Features
- 🔐 Authentication & Authorization - JWT-based auth with API keys, RBAC, and OAuth2
- 📊 Comprehensive Logging - Request/response logging, audit trails, performance metrics
- ⚡ Rate Limiting - IP-based rate limiting with sliding window algorithms
- 🛡️ Smart Rate Limiting - Redis-backed with memory fallback and proxy detection
- 🔍 MCP Server Discovery - Dynamic registration and health checking
- 🌐 Service Virtualization - Wrap non-MCP services as virtual MCP servers
- 🔌 Multi-Protocol Support - JSON-RPC, WebSocket, SSE, HTTP, and STDIO transports
- 🚀 High Performance - Built with Go and Gin for maximum throughput and low latency
- 🏢 Namespace Management - Group and organize MCP servers into logical namespaces
- 🔍 MCP Inspector - Real-time debugging and testing interface
- 🤝 Agent-to-Agent (A2A) - Agent-to-agent authentication and communication
- 🔧 Plugin System - Extensible middleware with content filters and AI integrations
- 📡 Endpoint Management - Dynamic REST endpoint creation with OpenAPI generation
- 🛠️ Content Filtering - PII detection, regex filtering, and resource protection
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.

mcp-gateway CLAUDE.md is an instructions file published in the GitHub repository theognis1002/mcp-gateway (41 stars, last pushed 6mo ago), licensed Apache-2.0. It adds 8,132 tokens to every session, about $0.0407 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
