A fenced bash/python block in SKILL.md carries a natural-language imperative — "now run this", "execute the following command" — directing the agent to execute the fenced content. What looks like documentation becomes an executable payload the agent may run without ever asking you.

An MCP server housing various Zoo built utilities
<!-- mcp-name: io.github.KittyCAD/zoo-mcp -->
ZOO_API_TOKEN set to your API key export ZOO_API_TOKEN="your_api_key_here" uv venv uv pip install git+ssh://[email protected]/KittyCAD/mcp.gitThe server can be started by using uvx
uvx zoo-mcpThe server can be started locally by using uv and the zoo_mcp module
uv run -m zoo_mcpThe server can also be run with the mcp package
uv run mcp run src/zoo_mcp/server.pyEach GitHub release also attaches standalone executables (built with PyInstaller) for Linux (x86_64, arm64), macOS (arm64, x86_64), and Windows (x86_64) — no Python toolchain required. Download the binary for your platform, set ZOO_API_TOKEN, and run it directly, e.g.:
ZOO_API_TOKEN="your_api_key_here" ./zoo-mcp-linux-x86_64The binaries are not code-signed, so macOS Gatekeeper and Windows SmartScreen may warn on first run.
The server can be used as is by running the server or importing directly into your python code.
from zoo_mcp.server import mcp
mcp.run()Individual tools can be used in your own python code as well
from mcp.server.fastmcp import FastMCP
from zoo_mcp.zoo_tools import zoo_execute_kcl
mcp = FastMCP(name="My Example Server")
@mcp.tool()
async def my_execute_kcl(kcl_code: str) -> tuple[bool, str]:
"""
Example tool that uses the zoo_execute_kcl function from zoo_mcp.zoo_tools
"""
return await zoo_execute_kcl(kcl_code=kcl_code)The server can be integrated with Claude desktop using the following command
uv run mcp install src/zoo_mcp/server.pyThe server can also be integrated with Claude Code using the following command
claude mcp add --scope project "Zoo-MCP" uv -- --directory "$PWD"/src/zoo_mcp run server.pyThe server can also be tested using the MCP Inspector
uv run mcp dev src/zoo_mcp/server.pyFor running with codex-cli
codex \
-c 'mcp_servers.zoo.command="uvx"' \
-c 'mcp_servers.zoo.args=["zoo-mcp"]' \
-c mcp_servers.zoo.env.ZOO_API_TOKEN="$ZOO_API_TOKEN"You can also use the helper script included in this repo:
./codex-zoo.shThe script prompts for a request, runs Codex with the Zoo MCP server, and saves a JSONL transcript (including token usage) to codex-run-<timestamp>.jsonl.
