Lets any MCP client (Claude Desktop, opencode, Cursor, ...)\nbrowse games, inspect mods and files, run free-text searches, download mod files with\nchecksum verification, manage endorsements, comments, collections, and user preferences.\n\n## Highlights\n\n- **Full API coverage** — 74 read tools + 66 mutations across v1 REST and v2 GraphQL.\n  Includes things v1 doesn't offer: free-text mod search, batch mod lookups, comment\n  threads, collection lifecycle, and quota-free GraphQL reads.\n- **Built-in TTL cache** — repeated identical GETs within a session don't consume quota\n  (games 1h, mod/file data 5 min, GraphQL POSTs 60 s). Personal state (`/user/*`) is\n  never cached.\n- **Dual authentication** — personal API key out of the box; optional OAuth2 (PKCE S256)\n  with auto-refresh for user-context mutations that API keys cannot perform.\n- **Safe downloads** — `nexus_download_mod_file` streams from the CDN to disk, verifies\n  MD5 + SHA-256 checksums against the expected hashes, and enforces a configurable size cap.\n- **Rate-limit transparency** — every v1 response carries an `_rl` snapshot of Nexus'\n  hourly/daily limit headers.\n\n## Install\n\n```bash\n# uv (recommended for MCP servers)\nuvx --from nexus-mods-mcp nexus-mcp\n\n# pipx\npipx install nexus-mod…","publisher":{"name":"Talya1412","url":null},"homepage":"https://github.com/Talya1412/nexus-mcp","repository":"https://github.com/Talya1412/nexus-mcp","version":"1.4.1","license":"MIT","protocols":["mcp"],"tags":["mcp","nexus-mods","model-context-protocol","api","fastmcp"],"pricing":null,"endpoints":[{"url":"pypi:nexus-mods-mcp","type":"package_pypi","auth":null,"probeable":false}],"skills":null,"tools":null,"extra":null,"attribution":{"kind":"pypi","name":"pypi","license":"pypi","repoUrl":"pypi","summary":"pypi","version":"pypi","description":"pypi","homepageUrl":"pypi","publisherName":"pypi"}},"derived":{"capabilities":[{"slug":"data.apis","name":"API Access","confidence":0.814,"provenance":"derived"}],"categories":["data"],"language":"en"},"observed":{"status":"unknown","statusReason":"Distributed as a package to run locally; no network endpoint to check.","lastOkAt":null,"lastProbedAt":null,"statusComputedAt":null,"reliability30d":null,"latestObservations":[],"tools":null,"package":{"name":"nexus-mods-mcp","registry":"pypi","observedAt":"2026-09-10T08:27:18.080Z","publishedAt":"2026-09-01T18:31:00.947997Z","latestVersion":"1.4.1"}},"verification":{"claimed":false,"claimedAt":null,"proofs":[]},"provenance":{"sources":[{"source":"pypi","key":"nexus-mods-mcp","url":"https://pypi.org/project/nexus-mods-mcp/","firstSeenAt":"2026-09-10T08:25:09.318Z","fetchedAt":"2026-09-10T08:25:09.318Z","normalizedAt":"2026-09-10T08:25:09.318Z"}]},"firstSeenAt":"2026-09-10T08:25:09.318Z","updatedAt":"2026-09-10T08:27:18.080Z"}
