aid: harbinger-health name: Harbinger Health x-enrichment: date: '2026-08-04' status: enriched artifacts_added: 33 pass: local-v1 url: https://raw.githubusercontent.com/api-evangelist/harbinger-health/refs/heads/main/apis.yml x-type: company x-source: harvest:secondary-market description: >- Harbinger Health is a Cambridge, Massachusetts biotechnology company founded out of Flagship Pioneering's Flagship Labs in 2018 that is building blood-based early cancer detection on the premise that the earliest phases of oncogenesis are marked by the reactivation of core developmental programs. Its proprietary Harbinger HX platform pairs cell-free DNA methylation assay chemistry tuned for low tumour fraction with machine learning operating under biologically informed constraints, and supports cancer signal detection, tumour content estimation and tissue-of-origin inference. RESOLVE, the company's clinical application of that platform, is positioned to generate clarity in the uncertain window between suspicion of cancer and diagnosis, across cancer types and clinical contexts, and is run out of a CLIA-certified and CAP-accredited high-complexity laboratory. The company raised a 100 million dollar round to expand its blood-based detection suite and is led by CEO Ajit Singh with Chief Innovation Officer Tony Shuber, a co-founder of Exact Sciences. Harbinger Health's API posture is minimal and clinical rather than commercial: there is no developer portal, no published documentation, no OpenAPI, no SDKs, no pricing and no self-serve API access, and the developer., docs., api., portal., status. and trust. subdomains do not resolve. What it does publish is unusual for a company with no developer programme - the corporate site serves a live, anonymously readable WordPress REST API (268 routes across 15 namespaces), an RFC 8414 OAuth 2.1 authorization-server metadata document, an RFC 9728 protected-resource document, and a real Model Context Protocol server namespace gated behind an mcp scope, alongside the WordPress Abilities API. That makes Harbinger Health machine-discoverable at the agent layer while none of its clinical, laboratory or diagnostic capability is exposed programmatically to third parties. accessModel: pricing: free onboarding: unknown trial: false try_now: false public: false label: No published developer API; corporate-site content and MCP surfaces only confidence: high source: - probe generated: '2026-08-04' method: probed image: https://kinlane-images.s3.amazonaws.com/shared/apis-json/apis-json-logo.jpg tags: - Health - Healthcare - Biotechnology - Cancer Detection - Diagnostics - Genomics - Artificial Intelligence - Machine Learning - Life Sciences - Clinical Laboratory - Precision Medicine - United States - Company created: '2026-08-04' modified: '2026-08-04' specificationVersion: '0.23' maintainers: - FN: Kin Lane email: kin@apievangelist.com - FN: APIs.json email: info@apis.io apis: - aid: harbinger-health:harbinger-health-mcp-server name: Harbinger Health MCP Server description: >- A live Model Context Protocol server namespace published on Harbinger Health's own host at https://harbinger-health.com/wp-json/mcp/, exposing two servers - mcp-oauth-server and mcp-adapter-default-server - over POST/GET/DELETE. It is protected by a real OAuth 2.1 deployment: https://harbinger-health.com/.well-known/oauth-authorization-server returns RFC 8414 metadata (authorization code with PKCE S256, refresh tokens, public clients, client ID metadata documents) and https://harbinger-health.com/.well-known/oauth-protected-resource returns RFC 9728 metadata naming the MCP server as the protected resource with a single mcp scope. An anonymous tools/list JSON-RPC call returns HTTP 401 mcp_unauthorized, so the tool catalogue and its input schemas require an authenticated introspection; the tool set is almost certainly drawn from the WordPress Abilities API registered at wp-abilities/v1, which is likewise 401 to anonymous callers. This is a site-content agent surface, not a clinical or diagnostic one. humanURL: https://modelcontextprotocol.io/ baseURL: https://harbinger-health.com/wp-json/mcp/mcp-oauth-server tags: - MCP - Agents -
