This server grounds\nagents in the real docs instead of guesses:\n\n- **Semantic search** (BGE-M3 dense + sparse embeddings) so natural-language\n  queries in English or 中文 find the right API even without exact names.\n- **Exact-name channel**: a literal CamelCase name in your query (e.g.\n  `CavityMillingBuilder`) is looked up directly and pinned to the top\n  (types first) — never left to approximate matching.\n- **RRF fusion** available to combine channels — though evaluation made\n  dense + exact the default (see [Evaluation](#evaluation)).\n\nEverything runs locally and offline against an index built from your own\nlicensed NX installation — no Siemens files are ever bundled with this\nrepo or sent anywhere.\n\n## Quick start\n\nRequires **Python 3.11+**.\n\n```bash\n# 1. Install from PyPI (or run without installing: uvx nxopen-mcp)\npip install \"nxopen-mcp[embed,reflect]\"\n\n# 2. Build the index from YOUR NX installation (one-time — see time note below)\nnxopen-mcp index --nx-path \"D:\\Siemens\\NX12.0\"\n\n# 3. Register with Claude Code (user scope: available in every project)\nclaude mcp add -s user nxopen -- nxopen-mcp serve\n\n# 4. Ask Claude Code to write NXOpen code — it now queries real APIs.\n```\n\n`index` looks for `NXOpen*.xml` doc files under `<nx-path>\\UGII\\managed`\n(falling back to `<nx-path>` itself), and for `NXOpen*.dll` assemblies in\nthe same folder.\n\nExtras: `[embed]` pulls in `FlagEmbedding` (downloads the ~2GB BGE-M3\nmodel on first use) — required for indexing and semantic search.\n`[reflect]` …","publisher":null,"homepage":null,"repository":"https://github.com/mingfeng6684/nxopen-mcp/issues","version":"0.2.0","license":null,"protocols":["mcp"],"tags":["cam","llm","mcp","nxopen","rag","siemens-nx"],"pricing":null,"endpoints":[{"url":"pypi:nxopen-mcp","type":"package_pypi","auth":null,"probeable":false}],"skills":null,"tools":null,"extra":null,"attribution":{"kind":"pypi","name":"pypi","repoUrl":"pypi","summary":"pypi","version":"pypi","description":"pypi"}},"derived":{"capabilities":[{"slug":"data.vector-search","name":"Vector Search","confidence":1,"provenance":"declared"},{"slug":"code.documentation","name":"Code Documentation","confidence":0.848,"provenance":"derived"}],"categories":["code","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":"nxopen-mcp","registry":"pypi","observedAt":"2026-09-10T08:27:29.299Z","publishedAt":"2026-07-15T14:43:51.079539Z","latestVersion":"0.2.0"}},"verification":{"claimed":false,"claimedAt":null,"proofs":[]},"provenance":{"sources":[{"source":"pypi","key":"nxopen-mcp","url":"https://pypi.org/project/nxopen-mcp/","firstSeenAt":"2026-09-10T08:25:49.419Z","fetchedAt":"2026-09-10T08:25:49.419Z","normalizedAt":"2026-09-10T08:25:49.419Z"}]},"firstSeenAt":"2026-09-10T08:25:49.419Z","updatedAt":"2026-09-10T08:27:29.299Z"}
