Source-Available

Why source-available?

MCP is an open protocol, and we believe the gateway that connects your tools to AI should be transparent too. You should be able to inspect every line of code that touches your credentials and data.

Switchboard is released under the Elastic License 2.0 — free to use, modify, self-host, and run internally. The only restriction is that you can't resell it as a competing hosted service. Everything else is fair game.

The source-available Switchboard gives you:

• 36+ integrations with automatic token-saving compaction (~90% reduction)
• Built-in dashboard tracking tokens and dollars saved in real time
• Bring your own integrations — implement the Go mcp.Integration interface or deploy Wasm plugins
• Local-first design — runs on your machine, your data stays local
• Works with Cursor, Claude Desktop, and any MCP client
• Web UI for configuration
• Available on Homebrew, Scoop, APT, and more

Your exit path is real

Platform independence is not a slogan. The core is source-available under the Elastic License 2.0, so you can inspect every line that touches credentials, run it on your own machines, or move off managed Hosted without rewriting your MCP clients.

• Any MCP client - the wire protocol is open; you are never tied to our UI.
• Any model - Switchboard is the tool plane, not the model plane.
• Self-host or managed - deploy it your way; Hosted adds teams, SSO, policies, and audit.

Architecture

Switchboard Hosted is split into two binaries:

The two processes communicate over an internal API. The runtime has no database access and no knowledge of users or billing — it only knows about integrations and credentials pushed to it by the UI.
