Manage your Webpushr directly from Claude Code with zero worries about OAuth hassles, API-breaking issues, or reliability and security concerns. You can do this in two different ways: Via Composio Connect - Direct and easiest approach Via Composio SDK - Programmatic approach with more control
Webpushr is a web push notification platform for sending campaigns to subscribers, segments, custom audiences, and individual users. Use it to reach visitors in real time and track delivery performance without building notification infrastructure.
Manage your Webpushr directly from Claude Code with zero worries about OAuth hassles, API-breaking issues, or reliability and security concerns.
You can do this in two different ways:
1. Add the Composio MCP to Claude
2. Start Claude Code
claude3. Open your MCP list
/mcp4. Select Composio and click on Authenticate
5. This will redirect you to the Composio OAuth page. Complete the flow by authorizing Composio and you're all set.
The Webpushr MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Webpushr account. It provides structured and secure access to your push notification campaigns and subscriber metrics, so your agent can send notifications, target specific audiences, schedule campaigns, check subscriber counts, and monitor campaign performance on your behalf.
Composio SDK is the underlying tech that powers Rube. It's a universal gateway that does everything Rube does but with much more programmatic control. You can programmatically generate an MCP URL with the app you need (here Webpushr) for even more tool search precision. It's secure and reliable.
The Composio SDK follows a three-phase workflow:
# macOS, Linux, WSL
curl -fsSL https://claude.ai/install.sh | bash
# Windows PowerShell
irm https://claude.ai/install.ps1 | iex
# Windows CMD
curl -fsSL https://claude.ai/install.cmd -o install.cmd && install.cmd && del install.cmdTo install Claude Code, use one of the following methods based on your operating system:
cd your-project-folder
claudeOpen a terminal, go to your project folder, and start Claude Code:
COMPOSIO_API_KEY=your_composio_api_key_here
USER_ID=your_user_id_hereCreate a .env file in your project root with the following variables:
COMPOSIO_API_KEY authenticates with Composio (get it from Composio dashboard)USER_ID identifies the user for session management (use any unique identifier)npm install @composio/core dotenvInstall the Composio TypeScript library to create MCP sessions.
@composio/core provides the core Composio functionalitydotenv loads environment variables from your .env fileimport 'dotenv/config';
import { Composio } from '@composio/core';
const { COMPOSIO_API_KEY, USER_ID } = process.env;
if (!COMPOSIO_API_KEY || !USER_ID) {
throw new Error('COMPOSIO_API_KEY and USER_ID required in .env');
}
const composioClient = new Composio({ apiKey: COMPOSIO_API_KEY });
const composioSession = await composioClient.create(USER_ID, {
toolkits: ['webpushr'],
});
const composioMcpUrl = composioSession?.mcp.url;
console.log(`MCP URL: ${composioMcpUrl}`);
console.log(`\nUse this command to add to Claude Code:`);
console.log(`claude mcp add --transport http webpushr-composio "${composioMcpUrl}" --headers "X-API-Key:${COMPOSIO_API_KEY}"`);Create a script to generate a Composio MCP URL for Webpushr. This URL will be used to connect Claude Code to Webpushr.
What's happening
create() to create a Tool Router session for Webpushrmcp.url is the MCP server URL that Claude Code will usenode --loader ts-node/esm generate_mcp_url.ts
# or if using tsx
tsx generate_mcp_url.tsRun your TypeScript script to generate the MCP URL.
claude mcp add command from the outputclaude mcp add --transport http webpushr-composio "YOUR_MCP_URL_HERE" --headers "X-API-Key:YOUR_COMPOSIO_API_KEY"
# Then restart Claude Code
exit
claudeIn your terminal, add the MCP server using the command from the previous step. The command format is:
claude mcp add registers a new MCP server with Claude Code--transport http specifies that this is an HTTP-based MCP serverwebpushr-composio) is how you'll reference it--headers includes your Composio API key for authenticationAfter running the command, close the current Claude Code session and start a new one for the changes to take effect.
claude mcp listCheck that your Webpushr MCP server is properly configured.
webpushr-composio entry in the listIf everything is wired up, you should see your webpushr-composio entry listed:
The first time you try to use Webpushr tools, you'll be prompted to authenticate.
Once authenticated, you can ask Claude Code to perform Webpushr operations in natural language. For example:
Here's the complete code to get you started with Webpushr and Claude Code:
import 'dotenv/config';
import { Composio } from '@composio/core';
const { COMPOSIO_API_KEY, USER_ID } = process.env;
if (!COMPOSIO_API_KEY || !USER_ID) {
throw new Error('COMPOSIO_API_KEY and USER_ID required in .env');
}
const composioClient = new Composio({ apiKey: COMPOSIO_API_KEY });
const composioSession = await composioClient.create(USER_ID, {
toolkits: ['webpushr'],
});
const composioMcpUrl = composioSession?.mcp.url;
console.log(`MCP URL: ${composioMcpUrl}`);
console.log(`\nUse this command to add to Claude Code:`);
console.log(`claude mcp add --transport http webpushr-composio "${composioMcpUrl}" --headers "X-API-Key:${COMPOSIO_API_KEY}"`);You've successfully integrated Webpushr with Claude Code using Composio's MCP server. Now you can interact with Webpushr directly from your terminal using natural language commands.
Key features of this setup:
Next steps:
You can extend this by adding more toolkits, implementing custom workflows, or building automation scripts that leverage Claude Code's capabilities.
Every Webpushr action and event your agent gets out of the box.

Karan skipped his own birthday party to fix our critical issue. It was 10pm and he diverted his Waymo to help us instead. This really sets the bar — it shows the commitment you need when users rely on your software.
A lot of students tell us that the moment their connected tools start talking to each other inside Opennote feels almost magical. The agent just knows them, and it's immensely helped keep new users on the platform.
We chose Composio over Pipedream because it delivered depth where it mattered — niche tools and tricky edge cases other platforms simply ignored. That gave us confidence to scale without compromising.
As a solo builder, shipping fast is life or death. The only way I can outcompete incumbents is by outmanoeuvring them. Getting bogged down managing agent auth would have been a death sentence.
Before Composio, adding tool integrations was slow and resource-intensive. Each one could take weeks of engineering time, and maintaining them meant constantly keeping up with API changes.
With hands-on help from their founder, we integrated Gmail and Google Drive in just 30 minutes. This level of personal support and commitment is exactly what startups should strive for.
