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 | $0.01419 | $0.01419 |
| Opus 5.5 | $0.00568 | $0.00568 |
| Sonnet 5.5 | $0.00284 | $0.00284 |
| Haiku 4.5 | $0.00142 | $0.00142 |
Grade A, and why
mcpHydroSSH 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 2mo 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
mcpHydroSSH is an MCP (Model Context Protocol) server that provides SSH capabilities to Claude Code. It allows connecting to remote servers, executing commands, and maintaining persistent SSH connections.
Published:
- npm: https://www.npmjs.com/package/mcp-hydrocoder-ssh
- GitHub: https://github.com/hydroCoderClaud/mcpHydroSSH
High-Level Architecture
Core Components
-
MCP Server Layer (
src/index.ts- 724 lines)- Exposes 10 MCP tools
- Uses
@modelcontextprotocol/sdkfor stdio transport - Entry point:
#! /usr/bin/env node
-
SSH Manager (
src/ssh-manager.ts- 349 lines)SSHManagerclass manages multiple SSH connections- Connection pool:
Map<connectionId, SSHConnection> - Tracks
lastConnectionIdfor default connection behavior - Handles connection lifecycle, command execution, timeouts
-
Config Layer (
src/config.ts- 203 lines)- Loads and validates config from
~/.claude/ssh-mcp-config.json - Uses Zod schema validation
- Provides server config lookup by ID
- Supports add/remove/update server operations
- Loads and validates config from

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.
