How I built 16 open-source, includes Biopharma (latest) MCP packages in 120 days

Hey Indie Hackers,

When connecting LLMs or autonomous AI agents (Claude, Cursor, LangChain) to clinical databases, two major problems occur:

1. Unsanitized PII/PHI leaks passing directly into LLM prompts.
2. Lack of regulatory auditability (such as FDA 21 CFR Part 11 timestamping).

Over the last 120 days, I’ve been building and open-sourcing the SEOSiri Model Context Protocol (MCP) suite. Today, I launched package #16: @seosiri/biopharma-mcp on NPM.

⚙️ The Technical Architecture

We engineered the server in TypeScript using NodeNext resolution with a 4-layer defensive gateway:

1. Transport Protection Layer: CORS origin restrictions using environment configuration tokens.
2. OAuth2 Security Gateway: Cryptographic JWT Bearer token validation for remote SSE streams inside Express.
3. Data Privacy Loop: Automatic regex redaction of SSN, DOB, email, and phone patterns prior to memory serialization.
4. Data-at-Rest Encryption: AES-256-GCM authenticated encryption for PostgreSQL connection parameters.

🚀 What the Server Does (10 Zod Tools)
~ calculate_4pl_curve: Fits 4-Parameter Logistic non-linear sigmoidal dose-response curves.
~assess_parallelism: Computes shared slope and asymptotes consistency via F-Test and TOST metrics.
~calculate_z_factor: Validates microplate high-throughput screening metrics from positive/negative controls.
~export_cdisc_sdtm: Converts unstructured JSON records into CDISC SDTM v1.7 / Allotrope compliant data models.
~generate_gxp_audit_log: Records immutably hashed operation logs to stderr for FDA 21 CFR Part 11 auditing.

💡 Distribution & Business Model
~Open Source (MIT): Full source code on GitHub and NPM (npm install @seosiri/biopharma-mcp) to build developer trust and search authority.
~Edge Deployment: Deployed at biopharma.seosiri.com via Cloudflare Workers.
Interactive Portal: An interactive D3 network graph explorer at developers.seosiri.com (not ordered yet there but will soon).,For details reading, visit- https://www.seosiri.com/2026/08/biopharma-mcp.html
~B2B Consulting: Generating high-ticket consulting leads for custom enterprise MCP development, VPC setups, and compliance interlocks.
