How to Use the Calibre-Web MCP in OpenAI Agents SDK

Q: Can I run Calibre-Web tools with guardrails in OpenAI Agents SDK?

Yes. You can set up pre-execution checks on tools like synckobolibrary to ensure the agent only triggers syncs when a valid token is present.

Q: What happens if an agent requests a non-existent shelf?

The getopdsshelf tool returns an error from Calibre-Web, which the SDK passes back to your agent. Your agent can then catch this error and ask the user for a different shelf ID.

Control your Calibre-Web library and sync e-readers directly using your OpenAI Agents SDK.

Browse Calibre-Web catalogs via OpenAI Agents SDK

Your OpenAI Agents SDK uses the `get_opds_catalog` tool to read the main OPDS catalog feed directly from your Calibre-Web server. This lets your agent parse book categories, authors, and series formats, feeding that metadata directly into OpenAI's runtime and triggering guardrail validations before any data flows to the user. When building production setups, your agent uses this tool to check book availability instantly. You don't write custom routing logic; the SDK handles the discovery and exposes the library structure directly to your agent's context.

Query specific shelves using this MCP Server

The `get_opds_shelf` tool exposes specific shelf feeds to your OpenAI agent, allowing targeted collection searches over this MCP connection. By targeting specific collections, your agent pulls exact shelf contents without loading the entire library database, keeping token usage low. If an agent tries to pull an unauthorized shelf, the OpenAI guardrails intercept the request before execution. You track the entire call through the OpenAI developer dashboard to see exactly which shelf ID was requested.

Sync Kobo libraries with multi-agent handoffs

The `sync_kobo_library` tool updates your e-reader metadata and syncs your Kobo device straight from the Calibre-Web platform. Your main agent can hand off the sync job to a specialized device-management agent once it verifies your Kobo Token. Running this in production means you get strict validation of the Kobo Token before the sync runs. The SDK traces the token handoff and execution steps, ensuring your reading progress and book files stay aligned without manual intervention.

Setup guide

Set up Calibre-Web MCP in OpenAI Agents SDK

Prerequisites

Python 3.10+ installed
openai-agents package (pip install openai-agents)
Active Vinkius subscription with a valid endpoint token

1

Install the SDK

Run pip install openai-agents to install the OpenAI Agents SDK. The MCP integration is built-in — no extra dependencies needed.
2

Connect via SSE transport

Use MCPServerSse with your Vinkius endpoint URL. Replace [YOUR_TOKEN_HERE] with your token from cloud.vinkius.com. The SDK auto-discovers all Calibre-Web tools at runtime.
3

Create your Agent

Pass the MCP to Agent(mcp_servers=[server]). The agent receives Calibre-Web tools as native definitions — JSON schemas resolve automatically.
4

Run the agent

Call Runner.run(agent, prompt) to execute. The agent invokes the appropriate Calibre-Web tools and returns structured results. Copy the full example on the right to get started.

agent.py

import asyncio
from agents import Agent, Runner
from agents.mcp import MCPServerSse

async def main():
    async with MCPServerSse(
        url="https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
    ) as server:
        agent = Agent(
            name="Calibre-Web Agent",
            instructions="You have access to Calibre-Web tools.",
            mcp_servers=[server],
        )
        result = await Runner.run(agent, "List recent transactions")
        print(result.final_output)

asyncio.run(main())

Common questions about Calibre-Web MCP in OpenAI Agents SDK

You register the Calibre-Web MCP Server by passing its URL to the streamable HTTP parameters in your agent code. The OpenAI Agents SDK automatically discovers the OPDS and Kobo tools, making them instantly available for your agent to call.

Yes. You can set up pre-execution checks on tools like `sync_kobo_library` to ensure the agent only triggers syncs when a valid token is present.

Set cacheToolsList to true in your SDK configuration. This caches the list of Calibre-Web tools on the MCP Server so your agent doesn't waste network calls fetching the tool definitions on every turn.

The `get_opds_shelf` tool returns an error from Calibre-Web, which the SDK passes back to your agent. Your agent can then catch this error and ask the user for a different shelf ID.

Vinkius hosts the server in a zero-trust sandbox where your Kobo tokens and OPDS credentials are never stored persistently. The server only processes these tokens in memory during active sync requests and discards them immediately after the API call completes.
