Klavis
YC X25-backed platform providing 100+ pre-built MCP integrations with OAuth support for AI agents. Offers three products: Strata (intelligent connectors that optimize context window usage), MCP Integrations (pre-built connectors for services like Gmail, Slack, GitHub), and MCP Sandbox (scalable environments for LLM training and reinforcement learning). Available as cloud-hosted, self-hosted Docker, Python/TypeScript SDKs, or REST API.
Best When
You are building AI agents that need to connect to many external services through MCP, especially with OAuth authentication and multi-user support, and want pre-built integrations rather than building each connector from scratch.
Avoid When
You only need one or two simple MCP integrations, want to avoid any API key management overhead, or need deep customization that a platform abstraction layer would hinder.
Use Cases
- • Connecting AI agents to 100+ services through a unified MCP integration layer
- • Optimizing context window usage when agents need access to many tools simultaneously
- • Building multi-user AI applications with per-user OAuth credentials
- • LLM training and reinforcement learning with tool-use environments via MCP Sandbox
- • Self-hosting MCP servers for specific integrations (GitHub, Gmail, Slack, etc.)
- • Rapid prototyping of agent tool integrations without building custom connectors
Not For
- • Simple single-tool MCP setups (overkill for one integration)
- • Environments where cloud dependencies are unacceptable and self-hosting is too complex
- • Teams that need deep customization of individual connectors beyond what Strata provides
- • Use cases requiring only open-source with no API key management
