description: >-
  Aro Biotherapeutics is a Philadelphia-based biotechnology company developing tissue-targeted
  genetic medicines built on Centyrins, a proprietary engineered human protein scaffold that is
  small, stable and highly soluble. Aro conjugates Centyrins to oligonucleotide payloads
  (Centyrin-siRNA conjugates) to deliver RNA- and DNA-based therapeutics precisely to cells and
  tissues outside the liver, including muscle and immune cells. Its lead program, ABX1100, is a
  CD71-targeted Centyrin-siRNA conjugate for Pompe disease that has received FDA orphan drug
  designation. The company is privately held, raised a $41.5M Series B led by Cowen Healthcare
  Investments with participation from Johnson & Johnson Innovation, and is headquartered at 601
  Walnut Street, Philadelphia, PA. Aro publishes no developer program, API reference or SDK; the
  only machine-readable surface on its domain is the Wix-platform llms.txt and Site MCP endpoint.

  name: Aro Biotherapeutics Site MCP
  description: >-
    A live, anonymously reachable Model Context Protocol endpoint served from Aro Biotherapeutics'
    own host and advertised in the site's llms.txt. It is provided by the Wix platform, not built
    by Aro — it exposes generic Wix site tools (business details, site search, site API docs
    search, visitor-token issuance and a Wix REST API call/execute bridge) over the public content
    of www.arobiotx.com. A tools/list call returns 9 tools with real JSON Schema inputs. There is
    no Aro-authored API behind it.

  detail: >-
    Aro Biotherapeutics runs no developer programme and publishes no OpenAPI or SDK, but its Wix-hosted
    site does serve a real llms.txt and a live, anonymously callable Site MCP endpoint at
    /_api/mcp that returns 9 tools with JSON Schema inputs — both captured verbatim.
