klavis
The Klavis repository bundles three things under one README. Strata is described as intelligent connectors that optimise the agent's context window, so one MCP server can front many tools instead of listing each of them to the model. MCP Integrations are 100+ prebuilt servers with OAuth support. MCP Sandbox provides scalable MCP environments for LLM training and RL.
There are four ways in. The cloud-hosted route is the klavis.ai service. For self-hosting, the README shows pulling a Docker image such as `ghcr.io/klavis-ai/github-mcp-server` and running it on port 5000, and installing open-source Strata locally with `pipx install strata-mcp`, then adding stdio servers like Playwright with `strata add`. There are also Python and TypeScript SDKs, where you create a Strata instance for a user with servers such as Gmail and Slack, and a REST API at `api.klavis.ai`.
Note the split: the cloud service, SDKs and REST API need a Klavis API key, while the Docker images and Strata are the open-source parts. The repo is Apache-2.0, and the last push was 2026-06-01. The README is mostly a launcher page that points to the docs at klavis.ai, so check the documentation for per-integration details. This review is based on the README and repository data; we have not run it ourselves.

Who it fits
- You want one MCP server (Strata) to front many tools so the model's context window stays small.
- You want 100+ prebuilt MCP integrations with OAuth, so you skip writing auth flows.
- You also need MCP environments for LLM training and reinforcement learning, which the repository includes.
- You want everything self-contained: the cloud service, SDKs and REST API need a Klavis API key, and hosted OAuth passes user tokens through a third party.
- You want a single clear product: the repository bundles three, and the README is a short launcher page.
- You need a very actively developed project: our data shows the last push on 2026-06-01.
How it differs
vs open-connector★ 6.1kOpenConnector offers a much larger catalogue of Actions and keeps credentials away from the agent. Klavis is smaller (100+ MCP integrations) but adds Strata routing and a training sandbox.
