# Quaker Houghton

> Quaker Houghton (NYSE: KWR) is a global industrial process fluids company — metalworking, rolling, casting, forging and hydraulic fluids, and QH Fluid Intelligence fluid-management services. It publishes NO product API, developer portal or SDK. The only machine-readable surfaces are on its corporate WordPress host, home.quakerhoughton.com: two Events Calendar REST namespaces with served OpenAPI documents, and an OAuth-gated Model Context Protocol server discovered through RFC 8414 / RFC 9728 well-known documents. This file was generated by API Evangelist from those served documents on 2026-09-17; it was not published by Quaker Houghton (/llms.txt on the host returns 404).

## Machine surfaces

- [Events API (stable, tribe/events/v1)](https://home.quakerhoughton.com/wp-json/tribe/events/v1/doc): OpenAPI 3.0.0, 30 operations over events, venues, organizers, categories and tags. Reads are anonymous — GET /events answered HTTP 200 with total 0 events on 2026-09-17. Writes need a WordPress Application Password that is not offered publicly.
- [Events API (experimental, tec/v1)](https://home.quakerhoughton.com/wp-json/tec/v1/docs): OpenAPI 3.0.4, 16 operations with operationIds. Every data route answers 400 missing_experimental_endpoint_acknowledgement until the plugin's acknowledgement header is sent; use tribe/events/v1 instead.
- [MCP server](https://home.quakerhoughton.com/wp-json/mcp/mcp-oauth-server): remote MCP over HTTP (WordPress MCP Adapter). OAuth 2.1 authorization code + PKCE, single scope `mcp`, public clients via client-ID metadata documents. Anonymous tools/list returns 401 mcp_unauthorized; the tool inventory is unknown.
- [OAuth authorization-server metadata (RFC 8414)](https://home.quakerhoughton.com/.well-known/oauth-authorization-server/)
- [OAuth protected-resource metadata (RFC 9728)](https://home.quakerhoughton.com/.well-known/oauth-protected-resource/)
- [WordPress REST index](https://home.quakerhoughton.com/wp-json/): 31 namespaces, 519 routes; the `mcp`, `wp-abilities/v1`, `tec/v1` and `tribe/events/v1` namespaces are the ones above.

## Conventions

- Pagination: page / per_page; X-WP-Total, X-WP-TotalPages and RFC 5988 Link headers.
- Errors: WordPress envelope {"code","message","data":{"status"}} in application/json — not RFC 9457.
- Idempotency: none. Reversibility: DELETE trashes (410 on repeat, force=true for permanent); no restore operation. Rate limits: none documented, no headers observed.
