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 | $0.03838 | $0.03838 |
| Opus 5 | $0.01919 | $0.01919 |
| Sonnet 5 | $0.00768 | $0.00768 |
| Haiku 4.5 | $0.00384 | $0.00384 |
Grade B, and why
mcp-server-manager CLAUDE.md scanned grade B with 1 finding 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 6d 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.
Reads agent configuration directoriesmediumAgent snooping
.claude/, .codex/, .gemini/ hold keys, settings and other credentials a mod has no legitimate need for.

Project Overview
MCP Server Manager is a Go web application that centralizes management of Model Context Protocol (MCP) servers across multiple AI clients. It solves the problem of manually editing various JSON files for different MCP clients by providing a single YAML configuration file and web interface.
Key Features:
- Single binary with embedded assets (no external dependencies)
- Cross-platform support (Linux, macOS, Windows)
- Real-time web interface with HTMX
- Dark/light theme system with manual override and system preference detection
- Automatic client config synchronization
- Server order preservation in UI and configuration
- Systemd integration for auto-start
Development Guidelines
Important Development Notes
- DO NOT run
make run- The development server is already running in the background - DO NOT include Claude Code attribution in git commits - Use semantic commit messages instead
- Use semantic git commit format:
feat:,fix:,docs:,refactor:,chore:, etc. - Example:
feat: add syntax highlighting to config viewerinstead of generic attribution - After completing a task, ask for confirmation then check it in the TODO list below and suggest the commit message

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-server-manager CLAUDE.md is an instructions file published in the GitHub repository vlazic/mcp-server-manager (20 stars, last pushed 11mo ago), licensed MIT. It adds 3,838 tokens to every session, about $0.0192 per session on Opus 5. A static security scan graded it B with 1 finding (reads agent configuration directories). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
