Before you use it
  • The repository lacks implementation or documentation for least privilege, user confirmation, or data flow transparency, posing security risks.
  • Dependency security is unverified, and no dependency manifest or lock files are provided.
  • Claims in the README (e.g., 100+ prebuilt integrations) lack supporting evidence and should be treated with caution.

What does this agent do, and when should you use it?

Klavis AI is an open-source MCP (Model Context Protocol) integration platform that enables AI agents to reliably use external tools. It offers three core solutions: Strata (intelligent connectors that optimize context window), MCP Integrations (100+ prebuilt integrations with OAuth support), and MCP Sandbox (scalable MCP environments for LLM training and reinforcement learning). The platform supports cloud-hosted (klavis.ai) and self-hosted (Docker) deployment, and provides Python/TypeScript SDKs and a REST API. It includes examples like a GitHub MCP server and Playwright MCP integration. Klavis AI aims to bridge AI agents with external tools, improving reliability and scalability of tool use.

Klavis AI connects AI agents to external tools and services via the MCP protocol. It provides Strata to aggregate multiple MCP servers and optimize context window; 100+ prebuilt MCP integrations with OAuth2 support (e.g., Gmail, Slack); and an MCP sandbox for running MCP servers in isolated environments, suitable for LLM training and reinforcement learning. Users can create and manage MCP server instances via Python SDK (e.g., from klavis import Klavis), TypeScript SDK (e.g., import { KlavisClient } from klavis), or REST API (e.g., POST /v1/mcp-server/strata). For self-hosting, users can run independent MCP servers via Docker or install the Strata CLI with pipx.

  1. Developers needing to quickly integrate multiple external tools (like Gmail, Slack) into AI agents, saving development time via prebuilt MCP integrations.
  2. Teams that want to optimize context window, using Strata to aggregate multiple MCP servers and reduce token consumption.
  3. Engineers working on LLM training who need scalable tool environments for reinforcement learning experiments, using MCP sandbox.
  4. Applications requiring secure connections to external services with OAuth2, leveraging Klavis's integration support.
  5. Enterprises that prefer self-hosting MCP infrastructure, using Docker images (e.g., ghcr.io/klavis-ai/github-mcp-server) to deploy in their own environment.
  6. Developers building server-side integrations via REST API, calling Klavis endpoints for flexible control.

What are this agent's strengths and limitations?

Pros
  • Provides 100+ prebuilt MCP integrations covering common services, with OAuth2 support, reducing integration effort.
  • Strata aggregates multiple MCP servers to optimize context window, reducing token usage and improving efficiency.
  • Offers flexible deployment options: cloud, self-hosted, SDKs, and REST API, catering to diverse scenarios.
  • MCP sandbox provides scalable, isolated environments for LLM training and reinforcement learning.
  • Open source (Apache-2.0), allowing customization and self-hosting without vendor lock-in for the core.
Limitations
  • Cloud service relies on Klavis infrastructure, creating potential vendor lock-in; self-hosting requires maintenance.
  • SDK and API require an API key, which involves registration and potential costs (not specified in README).
  • Self-hosted MCP server examples are limited to GitHub and Playwright, coverage may be insufficient.
  • Documentation is primarily external; README lacks detailed API reference, requiring further reading.
  • MCP protocol and Strata are relatively new concepts, potentially requiring a learning curve.

How do you install or deploy this agent?

Klavis offers multiple installation options:

  1. Cloud-hosted: Visit klavis.ai to sign up and follow the quickstart guide.
  2. Self-host MCP servers: Pull Docker images, e.g., docker pull ghcr.io/klavis-ai/github-mcp-server:latest, then run docker run -p 5000:5000 ghcr.io/klavis-ai/github-mcp-server:latest.
  3. Install Strata: Use pipx to install pipx install strata-mcp, then add MCP servers like strata add --type stdio playwright npx @playwright/mcp@latest.
  4. Use SDK: Install Python or TypeScript SDK and set up an API key (obtainable from klavis.ai).

How do you use this agent?

After installation, depending on deployment method:
- For self-hosted MCP servers, interact via the exposed port (e.g., 5000) of the Docker container.
- For Strata, use the CLI to add and manage MCP servers.
- For SDK users, create a Klavis client instance, then call mcp_server.create_strata_server or mcp_server.create_server_instance with user ID and server names (like GMAIL, SLACK).
- For REST API, use curl to POST to https://api.klavis.ai/v1/mcp-server/strata with API key and JSON payload (e.g., {"user_id": "user123", "servers": ["GMAIL", "SLACK"]}).
For example, in Python:

from klavis import Klavis
klavis = Klavis(api_key="your-key")
strata = klavis.mcp_server.create_strata_server(user_id="user123", servers=["GMAIL", "SLACK"])

FAQ

What is the cost of using Klavis?
Pricing is not mentioned in the README; the cloud service may be fee-based, while self-hosting is open source and free. Contact the team or visit klavis.ai for details.
How do I obtain an API key?
You need to sign up at klavis.ai and create an API key in the console. Self-hosted users may not need an API key.
How do I manage multiple MCP servers when self-hosting?
You can use Strata to aggregate multiple servers, or run separate Docker containers and network them.
Can I use custom MCP servers?
Yes, Strata and SDK allow adding custom MCP servers, but they must adhere to the MCP protocol.
What is the MCP sandbox used for?
It provides scalable MCP environments for LLM training and reinforcement learning, with isolated runtime environments.
