When to use it
Useful when someone asks for non-toxic or certified home, baby or personal care products and wants the certification evidence rather than marketing claims, or wants background from NonToxicFinder articles.
Requirements
Remote endpoint at nontoxicfinder.com over streamable HTTP; no authentication, environment variables or headers declared.
Before you install
An empty search result means no certified match in this data, not that no such product exists. Results include lapsed and unverifiable claims, so read the read dates and status. Link to the url given in each result rather than building retailer links.
Enable the server for the chats that should use its tools.
Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.
Use with an agent
Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.
Read https://sourceweft.com/mcp/io.github.timmasterson%2Fnontoxicfinder/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.
Find products that hold a third-party certification NonToxicFinder has checked against the certifier's registry or the maker's page. Only products with a current, recently read certification are returned. An empty list means no certified match in this data, not that none exists. Link people to the url given in each result and never construct a retailer link. Say "last read on <date>" for a certification. Say "brand-level" when evidence_scope is "brand". Ratings are scores, not certifications.
