MCPWorks with your agent SDK

One protocol.
Any agent.

Give your agent a provider's own MCP tools with one connection ID. Tokens are stored and refreshed per end user, so a single agent serves all of them.

Drop into the agent SDK you already use.

OpenAI Agents, the Claude Agent SDK, Vercel AI SDK, or a raw MCP client. One line hands it a provider's tools for a specific user.

MCP reference →
import { Agent, run, hostedMcpTool } from '@openai/agents';

const { url, token } = bundleup.mcp('conn_abc123').hosted();

const agent = new Agent({
  name: 'Assistant',
  tools: [
    hostedMcpTool({
      serverLabel: 'linear',
      serverUrl: url,
      authorization: token
    })
  ],
});
Per-user by design

One agent. Every user. The right token each time.

Each connection is one person's account at one provider. Agents act with exactly the access that person granted.

Agents that act for real people.
Safely.

The provider's own tools

Agents get the MCP tools each provider publishes, not a wrapper we wrote over them. BundleUp sits in front and handles auth.

Credentials stay with BundleUp.

Scoped access
read:issueswrite:commentsadmin

Only what the connected user granted.

One connection ID, everywhere
bundleup.proxy('conn_456')
bundleup.mcp('conn_456')

Connect once. Use it from code or from agents.

Fast agent loops

Tool calls run on the edge network, close to your users.

01
User connects an account

Through BundleUp's authorization page. You receive a connection ID.

02
Hand it to your agent

bundleup.mcp(id) for whichever user it's serving.

03
Let it call tools

Scoped to what the user granted. Tokens refresh in the background.
