A2 Biotherapeutics (A2 Bio) is a clinical-stage biotechnology company headquartered in Agoura Hills, California, founded in 2018 by Alexander Kamb, Michael Gallo and Paul Kang. It develops logic-gated cell therapies for solid tumors on its proprietary Tmod platform, a two-receptor activator/blocker design that lets an engineered T cell attack tumor cells which have lost an HLA allele while sparing normal cells that retain it. A2 Bio operates no developer API programme and publishes no product, clinical or research API. It is catalogued here because its corporate website runs a live WordPress REST API with 298 discoverable routes, and because that same install exposes two Model Context Protocol servers guarded by an OAuth 2.1 authorization server the host advertises through RFC 8414 and RFC 9728 metadata.
