⚠️ License change in 3.3.0

Starting with this release, mcp-gateway uses per-file licensing. The repository default is PolyForm Noncommercial 1.0.0; a small set of files marked SPDX-License-Identifier: MIT remain MIT. Commercial use of the noncommercial-licensed code requires a commercial license — see COMMERCIAL.md.

Versions 3.0.0–3.2.1 were published under MIT. That grant is irrevocable for those exact artifacts and is not withdrawn. Those versions are now deprecated (npm) and yanked (crates.io) so new installs resolve to 3.3.0; they remain available AS IS. Full model: LICENSES.md and NOTICE.md.

Installation

Cargo (Recommended)

cargo install mcp-gateway
