How to integrate Vast.ai MCP with OpenClaw
OpenClaw is the fastest growing agent harness out there, which can work 24/7 to automate almost any kind of tasks. However, its capabilities are limited to the tools it has access to. Composio allows your OpenClaw to access Vast.ai with authentication management handled for you. You can execute actions on Vast.ai via your favorite OpenClaw interface (Telegram, WhatsApp, TUI, etc), whichever you prefer.
Api Key
Vast.ai is a cloud GPU marketplace for renting compute from global providers. Use it to find flexible, low-cost GPU instances for AI training and inference.

Why use Composio?
Apart from a managed and hosted MCP server, you will get:
- Programmatic tool calling allows LLMs to write its code in a remote workbench to handle complex tool chaining. Reduces to-and-fro with LLMs for frequent tool calling.
- Handling Large tool responses out of LLM context to minimize context rot.
- Dynamic just-in-time access to 20,000 tools across 1000+ other Apps for cross-app workflows. It loads the tools you need, so LLMs aren't overwhelmed by tools you don't need.
How to install Vast.ai with OpenClaw
Using Composio API Key and Setup Prompt
- Go to dashboard.composio.dev
- Copy the setup prompt
- Run it in your OpenClaw chat interface.
- Authenticate Vast.ai from the dashboard
- Go back to your OpenClaw interface and start asking questions.
Using OpenClaw/Composio Plugin
1. Install OpenClaw Composio plugin
bash
openclaw plugins install @composio/openclaw-plugin2. Copy the API Key from dashboard.composio.dev
3. Setup OpenClaw Config
bash
openclaw config set plugins.entries.composio.config.consumerKey "ck_your_key_here"4. Restart OpenClaw
bash
openclaw gateway restart5. Go to your chat interface and start asking questions.
6. When prompted, authenticate the app and you're all set.
How It Works
The plugin connects to Composio's MCP server at https://connect.composio.dev/mcp and registers all available tools directly into the OpenClaw agent. Tools are called by name — no extra search or execute steps needed.
If a tool returns an auth error, the agent will prompt you to connect that toolkit at dashboard.composio.dev.
Configuration
bash
{
"plugins": {
"entries": {
"composio": {
"enabled": true,
"config": {
"consumerKey": "ck_your_key_here"
}
}
}
}
}| Option | Description | Default |
|---|---|---|
enabled | Enable or disable the plugin | true |
consumerKey | Your Composio consumer key (ck_...) | — |
mcpUrl | MCP server URL (advanced) | https://connect.composio.dev/mcp |
What is the Vast.ai MCP server, and what's possible with it?
The Vast.ai MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Vast.ai account. It provides structured and secure access to Vast.ai GPU compute offers, storage volume offers, and launch templates, so your agent can search rentable GPUs, compare compute options, find storage capacity, and discover suitable launch templates on your behalf.
- GPU offer search: Have your agent find currently rentable GPU compute offers that match your workload needs.
- Compute option comparison: Let the agent compare available GPU offers using verified marketplace criteria to help you choose a suitable option.
- Storage offer discovery: Direct your agent to search available storage volume offers for datasets, models, and other workload files.
- Launch template search: Instruct your agent to find Vast.ai launch templates using identifying details such as their names and metadata.
Conclusion
You've successfully integrated Vast.ai with OpenClaw using Composio plugin. Now interact with Vast.ai directly from your terminal, Web UI, or any messenger app using natural language commands.
Key benefits of this setup:
- Seamless integration across TUI, Web UIs, and Messenger apps like Telegram, WhatsApp, Slack, etc.
- Natural language commands for Vast.ai operations
- Managed authentication through Composio
- Access to 20,000+ tools across 1000+ apps for cross-app workflows
- Programmatic tool calling for complex tool chaining
Next steps:
- Try asking OpenClaw to perform various Vast.ai operations
- Explore cross-app workflows by connecting more toolkits like Calendar, Slack, Notion, etc.
- Build complex automation scripts that leverage OpenClaw's 24/7 running capabilities

FAQ
Frequently asked questions
With a standalone Vast.ai MCP server, the agents and LLMs can only access a fixed set of Vast.ai tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from Vast.ai and many other apps based on the task at hand, all through a single MCP endpoint.
Yes, you can. OpenClaw fully supports MCP integration. You get structured tool calling, message history handling, and model orchestration while Tool Router takes care of discovering and serving the right Vast.ai tools.
Yes, absolutely. You can configure which Vast.ai scopes and actions are allowed when connecting your account to Composio. You can also bring your own OAuth credentials or API configuration so you keep full control over what the agent can do.
All sensitive data such as tokens, keys, and configuration is fully encrypted at rest and in transit. Composio is SOC 2 Type 2 compliant and follows strict security practices so your Vast.ai data and credentials are handled as safely as possible.

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.
