Ask in plain\nlanguage, filter by engineering requirements, or download the whole thing.\n\n```\n\"Find a reaction wheel over 0.2 N·m·s that runs on a 12 V bus, under 2 kg\"\n\nA meets every requirement VRW-B-02 · Vectronic · 0.2 N·m·s · 9–36 V · 1000 g\nB fails a named requirement RW-0.06 · momentum 0.06 N·m·s — need ≥ 0.2\nC could fit, data not published NanoTorque GSW-600 · missing: supply voltage\n```\n\nThree rules make the data usable by a machine:\n\n* **Nothing is guessed.** A missing property means the vendor does not publish\n it, and the item is reported as \"data missing\" rather than silently dropped\n or filled with a typical value.\n* **Conditions are kept apart.** Idle, steady-state and peak power are separate\n records with their measurement condition attached — never averaged into one\n number.\n* **Every value is traceable.** Source file and page, plus a confidence level:\n `L0` machine-extracted, `L1` verified by a human against the vendor datasheet.\n\n---\n\n## Use it from an AI assistant (MCP)\n\n**Hosted — no install.** Add this as a custom connector in Claude, ChatGPT\n(developer mode) or any MCP client:\n\n```\nhttps://newspacemarket.com/mrd-connect/mcp\n```\n\n**Local — for editors that speak stdio** (Cursor, Windsurf, VS Code, Claude\nDesktop). Add to your MCP config:\n\n```json\n{\n \"mcpServers\": {\n \"mrd\": {\n \"command\": \"npx\",\n \"args\": [\"-y\", \"@newspacemarket/mrd-mcp\"]\n }\n }\n}\n```\n\nThe package is a thin bridge: it speaks stdio to your editor and forwards to the\nhosted endpoint, so new tools appear without upgrading anything.\n\nThree tools arrive in the assistant:\n\n| tool | what it does |\n|------|--------------|\n| `match_components` | reverse search — requirements in, candidates grouped A / B / C with per-parameter verdicts |\n| `get_component_specs` | the full typed layer of one category, for your own comparison or trade study |\n| `build_budget` | mass and steady-state power of a stack, with bus-voltage checks and an honest list of what could not be counted |\n\n## Where it is listed\n\n* **Official MCP Registry** — `io.github.newspacemarket-com/mrd`\n* **Smithery** — [`info-zrja/newspace-mrd`](https://smithery.ai/servers/info-zrja/newspace-mrd),\n one-click install into Claude, Cursor, VS Code and other clients\n* **Dataset mirror** — [Hugging Face](https://huggingface.co/datasets/NewSpaceMarket/mrd)\n\n## Use it from code\n\nNo authentication for reading. An optional free key raises rate limits\nfive-fold — request one at [/mrd-connect/](https://newspacemarket.com/mrd-connect/).\n\n```bash\ncurl \"https://newspacemarket.com/mrd-connect/match?category=star-trackers&accuracy_max=10&bus_v=12\"\n```\n\n* [`examples/python/select_wheels.py`](examples/python/select_wheels.py) — reverse search, printing why each candidate passed or failed\n* [`examples/python/budget.py`](examples/python/budget.py) — assemble a stack and budget it through the MCP tools\n* [`examples/js/match.mjs`](examples/js/match.mjs) — same search from Node, no dependencies\n* [`examples/curl.md`](examples/curl.md) — every endpoint as a one-liner\n\n**OpenAPI 3.1**: [`openapi.json`](openapi.json), served live at\n`https://newspacemarket.com/mrd-connect/openapi.json`. Import it as a ChatGPT\nCustom GPT Action, a LangChain / CrewAI / n8n toolkit, or convert it to Gemini\nfunction declarations.\n\n## Download the data\n\n[`data/`](data/) holds a dated snapshot, regenerated as the layer grows:\n\n| file | contents |\n|------|----------|\n| `mrd-full.json` | everything — products, values, property dictionary |\n| `mrd-values.csv` | one row per value: product, property, number, unit, bound, condition, source, confidence |\n| `mrd-products.csv` | one row per product: name, manufacturer, category, URL |\n| `mrd-properties.csv` | the property dictionary — what each key means and its canonical unit |\n\nLive data is always newer than the snapshot; use `get_component_specs` or\n`/mrd-connect/specs?category=…` when freshness matters.\n\n## How the data is built\n\nValues are extracted from vendor datasheets (text and, for scanned documents,\npage images), from vendor product pages, and from product descriptions — the\nsource of every record says which. Units are converted **by code**, not by a\nmodel: kg to g, dBm to W, psi to bar, tf to mN. A validation pass rejects a\nfigure whose unit does not match the property, and an outlier scan flags values\nthat sit far from the category median for human review.\n\nCoverage is not exhaustive. Where a vendor publishes nothing machine-readable,\nthe product simply is not here — and where a required field is missing, the\nAPI says so by name instead of guessing.\n\n## Licence\n\n* **Code** (the MCP bridge and examples): MIT — see [`LICENSE`](LICENSE).\n* **Data** in `data/`: CC BY 4.0, attribution \"NewSpace Market\" — see\n [`data/LICENSE-DATA`](data/LICENSE-DATA).\n\nSpecifications are extracted from publicly published vendor materials and are\nprovided as-is. Verify against the vendor datasheet before committing to a\ndesign.\n\n## Links\n\n* Connection hub: \n* AI component designer: \n* Catalogue: \n\nAre you a vendor whose products are listed?
