Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00065 | $0.02136 |
| Opus 5 | $0.00032 | $0.01068 |
| Sonnet 5 | $0.00013 | $0.00427 |
| Haiku 4.5 | $0.00006 | $0.00214 |
Grade D, and why
mcp-server-manager scanned grade D with 2 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.

.claude/, .codex/, .gemini/ hold keys, settings and other credentials a mod has no legitimate need for.

MCP Server Manager
Overview
MCP (Model Context Protocol) servers connect Claude Code to external tools, databases, and APIs. This skill provides guidance for installing, configuring, and managing MCP servers using the claude mcp command-line interface.
Quick Reference
Essential Commands
List all configured MCP servers:
claude mcp list
Get details about a specific server:
claude mcp get <server-name>
Remove a server:
claude mcp remove <server-name>
Check server status (from within Claude Code):
/mcp
Adding MCP Servers
Transport Types
MCP servers use one of three transport protocols. Choose the appropriate transport based on the server type:
HTTP Transport (Remote Servers)
For cloud-based services providing HTTP endpoints:
# Basic syntax
claude mcp add --transport http <name> <url>
# Example: Add Notion server
claude mcp add --transport http notion https://mcp.notion.com/mcp
# With authentication header
claude mcp add --transport http secure-api https://api.example.com/mcp \
--header "Authorization: Bearer YOUR_TOKEN"
SSE Transport (Server-Sent Events)
For remote servers using SSE protocol:
# Basic syntax
claude mcp add --transport sse <name> <url>
# Example: Add Webflow server
claude mcp add --transport sse webflow https://mcp.webflow.com/sse
# With API key header
claude mcp add --transport sse private-api https://api.company.com/sse \
--header "X-API-Key: YOUR_KEY"
Stdio Transport (Local Process)
For servers running as local processes with stdio communication:
# Basic syntax
claude mcp add --transport stdio <name> [--env KEY=VALUE ...] -- <command> [args...]
# Example: Add Airtable server
claude mcp add --transport stdio airtable \
--env AIRTABLE_API_KEY=YOUR_KEY \
-- npx -y airtable-mcp-server
# Example: Add local Python server
claude mcp add --transport stdio custom-db \
--env DB_URL=postgresql://localhost/mydb \
-- python3 /path/to/server.py
What ships with it
2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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 is a skill published in the GitHub repository tdimino/claude-code-minoan (41 stars, last pushed yesterday), licensed MIT. It adds 65 tokens to every session and 2,136 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it D with 2 findings (reads agent configuration directories, recursive force delete). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
