Build a Faro AI Clinical-Trial MCP Server for Agentic Healthcare Data Access in 2026

Faro AI raised a $37.3M Series B co-led by Merck Global Health Innovation Fund and S32 on August 30, 2026. Six of the top 10 pharma companies use Faro's structured clinical-development data platform. The capital targets a 50% reduction in clinical-trial timelines.

This guide builds a FastMCP server that exposes clinical-trial data operations as MCP tools: protocol search, patient-cohort matching, eligibility verification, and FDA-compliant dossier generation.

Step 3: Configure Claude Desktop

{
  "mcpServers": {
    "faro-clinical": {
      "command": "node",
      "args": ["/path/to/faro-clinical-mcp/dist/index.js"],

MCP Tool Reference

Production Reality Check

1. HIPAA compliance: All patient data must be de-identified (Safe Harbor method) before reaching the MCP server. Use patient_id hashes, not names.
2. 21 CFR Part 11: The dossier generator creates SHA-256 audit hashes for every entry. For FDA submission, add digital signatures via PKCS#7.
3. Access control: The MCP server should integrate with OAuth 2.0 and enforce RBAC — only authorized clinicians can access patient-matching tools.
4. Audit logging: Log every MCP tool call to an immutable append-only store (e.g., AWS CloudTrail or a PostgreSQL audit table).
5. Faro integration: In production, replace the simulated data layer with Faro AI's API for real structured clinical-development data.
