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
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 8d 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.

Architecture Overview
MCP-Gateway is an HTTP reverse proxy for MCP (Model Context Protocol) servers with OAuth authentication and webhook-based observability.
Key Components
- HTTP Server (
cmd/serve.go): Cobra CLI with hot-reloading config via fsnotify - OAuth Manager (
oauth/): JWT validation using JWK sets, integrates with Dex identity provider - Proxy Handler (
proxy/):- Reverse proxy with MCP-aware transport
- Intercepts JSON-RPC messages for session tracking
- Supports SSE (Server-Sent Events) for streaming
- Webhook System (
webhook/): Async notifications with full request/response context
Important Design Patterns
- Config Hot-Reload: Uses fsnotify to watch config file changes
- Context Propagation: Structured logging with request context
- Transport Interception: Custom RoundTripper for MCP protocol awareness
- Per-Route Auth: Authentication can be disabled for specific routes (e.g., public endpoints)
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 hyprmcp/mcp-gateway (92 stars, last pushed 4mo ago), licensed MIT. It adds 296 tokens to every session, about $0.0015 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.
