generated: '2026-08-13' method: searched source: >- Registry metadata from registry.npmjs.org, crates.io and the MutinyHQ GitHub organization, plus the Mutiny Help Center. npm, PyPI, RubyGems, Maven Central, NuGet, pkg.go.dev, Packagist and crates.io were all queried for first-party Mutiny client libraries. notes: >- Mutiny publishes no general-purpose REST API, so there is no server-side API client SDK family. The one first-party client library on a public registry is @mutinyhq/react-sdk, which wraps the LEGACY website-personalization product and has not shipped a release since 2023-03-27 — its source repository (github.com/MutinyHQ/web-sdks) now returns 404. The current programmatic entry point is the hosted MCP server, which needs no client library (any MCP client speaks to it over HTTP + OAuth). mutiny-diff/mdiff is a first-party open-source developer tool published by the company; it is NOT a client for the Mutiny product API and no CLI pointer is emitted for it. packages: - language: javascript registry: npm name: "@mutinyhq/react-sdk" url: https://www.npmjs.com/package/@mutinyhq/react-sdk install: npm install @mutinyhq/react-sdk official: true api_client: true version: 0.1.2 published: '2023-03-27' source_repo: https://github.com/MutinyHQ/web-sdks note: >- First-party React SDK for the legacy Mutiny website-personalization product. Three published versions (0.1.0, 0.1.1, 0.1.2); latest release 2023-03-27, more than three years before this pass. The declared source repository github.com/MutinyHQ/web-sdks returns HTTP 404, so the package is effectively unmaintained — a decay signal, recorded rather than hidden. - language: rust registry: crates.io name: mutiny-diff url: https://crates.io/crates/mutiny-diff install: cargo install mutiny-diff official: true api_client: false version: 0.1.22 published: '2026-03-25' source_repo: https://github.com/MutinyHQ/mdiff note: >- First-party open-source terminal UI (binary name `mdiff`) for reviewing git diffs from coding-agent worktrees.
