klavis vs open-connector
klavis: Klavis offers solutions like Strata for intelligent AI agent connectors, optimizing context windows, and MCP Integrations with over 100 prebuilt, OAuth-supported tools. It also provides an MCP Sandbox for scalable LLM training and reinforcement learning environments.; open-connector: OpenConnector is an open-source connector gateway that allows AI agents and applications to connect to over 1,000 providers and utilize 10,000+ prebuilt actions. It centralizes credential management and exposes a unified catalog, enabling robust and inspectable access to various user application accounts without exposing sensitive data to agent processes.
Editorial Head-to-Head Analysis
OpenConnector 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.
01
TL;DR
klavisAPI Integration · ★ 5.8k
When to choose:
- 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.
When to skip:
- 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.
open-connectorAPI Integration · ★ 6.1k
When to choose:
- You want your agents to use 1,000+ app integrations without handing provider credentials to the agent process.
- You want a self-hostable alternative to Composio, runnable with Docker, on Fly.io or on Cloudflare Workers.
- You want inspectable Action contracts (schemas, required scopes, executor source) with scopes, runtime tokens and allow and block policies.
When to skip:
- You need deep coverage of one service: integration depth varies across 1,000+ providers.
- You want no vendor path at all: hosted authentication and the commercial runtime come from OOMOL, and self-hosting means you run the runtime yourself.
- You do not want to connect and manage each provider's account, credentials and scopes.
