buffer

Use this skill when you need to work with buffer through its generated async Python app, call its MCP-backed functions from code, or inspect available functions with the mcp-skill CLI.

Authentication

This MCP server uses Bearer token authentication. The API key is persisted to ~/.mcp-skill/auth/ after first use, so subsequent runs can omit it.

# First use — provide and persist the key
app = BufferApp(auth="YOUR_API_KEY")

# Subsequent uses — loaded from disk automatically
app = BufferApp()

The key is sent as Authorization: Bearer <auth> on every request.

Dependencies

This skill requires the following Python packages:

• mcp-skill

Install with uv:

uv pip install mcp-skill

Or with pip:

pip install mcp-skill

Python Usage

Use the generated app directly in async Python code:

import asyncio
from buffer.app import BufferApp


async def main():
    app = BufferApp(auth="YOUR_API_KEY")
    result = await app.get_account()
    print(result)


asyncio.run(main())

Async Usage Notes

• Every generated tool method is async, so call it with await.
• Use these apps inside an async function, then run that function with asyncio.run(...) if you are in a script.
• If you forget await, you will get a coroutine object instead of the actual tool result.
• Be careful when mixing this with other event-loop environments such as notebooks, web servers, or async frameworks.

Discover Functions with the CLI

Use the CLI to find available apps, list functions on an app, and inspect a function before calling it:

uvx mcp-skill list-apps
uvx mcp-skill list-functions buffer
uvx mcp-skill inspect buffer get_account

Important: Add .agents/skills to your Python path so imports resolve correctly:

import sys
sys.path.insert(0, ".agents/skills")
from buffer.app import BufferApp

Or set the PYTHONPATH environment variable:

export PYTHONPATH=".agents/skills:$PYTHONPATH"

Preferred: use uv run (handles dependencies automatically):

PYTHONPATH=.agents/skills uv run --with mcp-skill python -c "
import asyncio
from buffer.app import BufferApp

async def main():
    app = BufferApp(auth='YOUR_API_KEY')
    result = await app.get_account()
    print(result)

asyncio.run(main())
"

Alternative: use python directly (install dependencies first):

pip install mcp-skill
PYTHONPATH=.agents/skills python -c "
import asyncio
from buffer.app import BufferApp

async def main():
    app = BufferApp(auth='YOUR_API_KEY')
    result = await app.get_account()
    print(result)

asyncio.run(main())
