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 | $0.00065 | $0.00897 |
| Opus 5 | $0.00032 | $0.00449 |
| Sonnet 5 | $0.00013 | $0.00179 |
| Haiku 4.5 | $0.00006 | $0.00090 |
Grade A, and why
mcp-scaffold 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 5d 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 Server Scaffolding
Scaffold production-ready Python MCP servers with FastMCP.
Quick Start
Generate a new MCP server:
python scripts/scaffold.py my-server --output ./my-server
This creates a complete project structure with:
server.py- Main server with example tool, resource, and promptrequirements.txt- Dependencies (fastmcp, pydantic)README.md- Usage instructions
Scaffolding Options
Minimal Server (Tools Only)
python scripts/scaffold.py my-server --template basic
Full Server (All Primitives)
python scripts/scaffold.py my-server --template full
With Specific Features
python scripts/scaffold.py my-server \
--tools \
--resources \
--prompts \
--lifespan \
--output ./servers/my-server
Validation
Validate an existing MCP server:
python scripts/validate.py path/to/server.py
Checks:
- FastMCP import and initialization
- Tool definitions with proper type hints
- Resource URI patterns
- Pydantic Field usage
- Async function patterns
Project Structure
Generated projects follow this structure:
my-server/
├── server.py # Main MCP server
├── requirements.txt # Python dependencies
├── README.md # Usage documentation
└── data/ # Default data directory (gitignored)
Templates
Basic Template
Minimal server with one tool:
from fastmcp import FastMCP
mcp = FastMCP("my-server")
@mcp.tool
def hello(name: str) -> str:
"""Greet someone by name."""
return f"Hello, {name}!"
if __name__ == "__main__":
mcp.run()
Full Template
Complete server with tools, resources, prompts, and lifespan. See assets/templates/full-server.py.

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-scaffold is a skill published in the GitHub repository timothywarner-org/claude-code (223 stars, last pushed 1mo ago), licensed MIT. It adds 65 tokens to every session and 897 once invoked, about $0.0003 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.
