Once you have part numbers, use your own product API or CAD/data-sheet pipeline for detailed assets.\n\nThis project is not affiliated with, endorsed by, or sponsored by McMaster-Carr.\n\n## Features\n\n- Headless-only browsing with SeleniumBase UC mode.\n- Stateful navigation across searches, categories, product pages, back, and current page.\n- Product number extraction from rendered links, images, and page HTML.\n- Dynamic schema extraction for rendered product tables: columns, row attributes, group headers, filters, and part-number rows.\n- Exact-part resolver that searches multiple query roots, extracts live rendered table schemas, maps constraints onto dynamic fields, and returns a part number only when matching rows collapse to one candidate.\n- GPT-backed schema matching with programmatic row filtering: the model proposes fields and accepted live values, while Python performs the actual filtering.\n- Dynamic handling for linked option variants, accessory rows, prefixed table columns, dimensions, materials, selected options, model numbers, and packaging.\n- MCP-safe stdio transport; browser logs are kept off protocol stdout.\n- Isolated temporary Chrome profile by default so stale user sessions do not break agent runs.\n- Automatic one-time browser reset/retry for common first-run ChromeDriver failures.\n- Sequential browser session with Selenium page-load timeouts.\n- Browser-free URL helper for fast product/search URL generation.\n\n## Requirements\n\n- Python 3.11 or newer\n- Google Chrome installed\n- Network access to `https://www.mcmaster.com`\n\nSeleniumBase downloads a matching driver automatically on first use. The first live request can take longer than later requests.\n\nFor exact-part re…","publisher":{"name":"Chancel Lavoie","url":null},"homepage":"https://github.com/cmuchancel/mcmaster-navigator-mcp","repository":"https://github.com/cmuchancel/mcmaster-navigator-mcp","version":"0.5.4","license":null,"protocols":["mcp"],"tags":["browser-automation","cad","mcmaster-carr","mcp","parts"],"pricing":null,"endpoints":[{"url":"pypi:mcmaster-navigator-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","homepageUrl":"pypi","publisherName":"pypi"}},"derived":{"capabilities":[{"slug":"infra.browser-automation","name":"Browser Automation","confidence":1,"provenance":"declared"},{"slug":"media.3d","name":"3D & Design","confidence":1,"provenance":"declared"}],"categories":["infra","media"],"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":"mcmaster-navigator-mcp","registry":"pypi","observedAt":"2026-11-03T11:24:55.619Z","publishedAt":"2026-05-12T07:37:31.180563Z","latestVersion":"0.5.4"},"toolSurface":null,"endpointFacts":[]},"verification":{"claimed":false,"claimedAt":null,"proofs":[]},"provenance":{"sources":[{"source":"pypi","key":"mcmaster-navigator-mcp","url":"https://pypi.org/project/mcmaster-navigator-mcp/","firstSeenAt":"2026-09-10T00:23:06.628Z","fetchedAt":"2026-11-03T11:24:19.313Z","normalizedAt":"2026-11-03T11:24:19.313Z"}]},"firstSeenAt":"2026-09-10T00:23:06.628Z","updatedAt":"2026-11-03T11:24:55.619Z"}
