Agentic Index
Arcade vs Klavis (2026)
Two takes on authenticated tool access for agents, one commercial and one open at the core.
Arcade is the managed option: OAuth and token handling across more than seven thousand integrations with an MCP runtime, from 25 dollars a month with a free tier, documenting 8 of 14. Klavis is MCP native with hosted servers across six hundred plus tools and the open source Strata server underneath, free to start, documenting 6. Arcade for reach and a managed path; Klavis when running the servers yourself is the requirement rather than a preference.
Choose Arcade if
- Integration reach decides it: seven thousand against six hundred is not a close call.
- You want prebuilt tooling and a managed runtime rather than infrastructure to operate.
- Documented coverage is broader, including observability and evaluation where Klavis is thin.
Choose Klavis if
- Open source is a requirement: Strata is code you can run, audit and modify.
- Self hosting the MCP servers is the point, not a fallback.
- You want to start free and scale usage without a per seat commitment.
