Overview

Klavis is open-source MCP integration for AI applications, providing a platform for reliable tool access at any scale. It features 100+ prebuilt integrations with OAuth support, a scalable MCP sandbox for LLM training and RL, and supports cloud-hosted, self-hosted, and SDK-based deployment options. Klavis supports multiple deployment methods, including cloud-hosted through klavis.ai, self-hosted, and SDK-based deployment using Python or TypeScript. For cloud-hosted deployment, users can access a quick start guide. For self-hosting, users can install the Open Source Strata locally using pipx, and access a range of MCP integrations. The platform also has REST API support, allowing users to create Strata servers and individual MCP servers programmatically. The documentation provides further information on available integrations, and the Discord community offers support and issue reporting. Klavis is built using a range of programming languages, including Python, Go, TypeScript, JavaScript, and Docker.

Q&A

What is MCP?

When building AI applications/agents, Model Context Protocols(MCP) enables tools to be added dynamically at runtime in a standardized way, eliminating the need for preconfigured integrations during design-time. Without MCP, tool integration requires manual database design&updates and custom formatting for each model, leading to significant complexity.

What is Klavis AI?

Klavis AI is building open-source infrastructure designed to make MCP easy for everyone to use, build, and scale. We provide Slack/Discord(and more!) clients, hosted MCP servers, and simple web UI to lower the barrier to entry for MCPs.

Asked by Bianca Ferreira · May 5, 2026

Is Klavis AI secure?

Klavis AI includes security features as part of its solution. Specifically, we offer Secure Integration with built-in OAuth support. This is designed to enable secure access to user resources when required by an MCP.

How does the Klavis AI API work?

The Klavis AI API provides a standardized RESTful interface to interact with MCP servers. Developers can easily integrate MCP functionality into their applications by making simple API calls, abstracting away the complexity of individual MCP implementations.
