Enterprise MCP Health Gateway

A runnable MVP for onboarding enterprise tenants and agents, exposing governed health capabilities through MCP, storing downstream credentials, and monitoring tool activity from an analytics dashboard.

Included

• Multi-tenant enterprise onboarding

• One-time admin and agent keys, stored only as SHA-256 hashes

• Per-agent tool and purpose permissions

• Encrypted downstream credential vault using Fernet

• Streamable HTTP MCP server using the stable official Python SDK line

• Deterministic policy enforcement outside the model

• Provider-neutral demo health tools

• Pseudonymized, structured audit events

• Dashboard for calls, success rate, denials, p95 latency, active agents and tool usage

• Docker Compose deployment

• Unit tests

The included health connector is synthetic and deterministic. Replace app/connectors/demo.py with a production adapter for Thryve or another health data provider.

Run with Docker

cp .env.example .env
docker compose up --build

Open the dashboard at http://localhost:8000.

Local demo credentials:

Admin key: adm_demo_change_me
Agent token: mcp_demo_change_me
MCP endpoint: http://localhost:8001/mcp

Change all demo keys and SECRET_KEY before using the project outside local development.

Test the MCP service

MCP_AGENT_TOKEN=mcp_demo_change_me python examples/client.py

The example client lists tools and calls prepare_prevention_brief for a synthetic member. The tool call appears in the dashboard within the next refresh.

Run without Docker

python -m venv .venv
source .venv/bin/activate
pip install -e ".[dev]"
mkdir -p data
cp .env.example .env

uvicorn app.api:app --reload --port 8000
python -m app.mcp_server

Admin API examples

Create a tenant:

curl -X POST http://localhost:8000/api/v1/onboard \
  -H 'Content-Type: application/json' \
  -d '{"organization_name":"Example Insurer","admin_email":"admin@example.com"}'

Create an agent:

curl -X POST http://localhost:8000/api/v1/agents \
  -H 'Content-Type: application/json' \
  -H 'X-Admin-Key: adm_demo_change_me' \
  -d '{
    "name":"Prevention Agent",
    "environment":"production",
    "allowed_tools":["list_authorized_capabilities","get_member_activity_summary","assess_data_quality","prepare_prevention_brief"],
    "allowed_purposes":["operational","prevention"]
  }'

Store a downstream credential:

curl -X POST http://localhost:8000/api/v1/credentials \
  -H 'Content-Type: application/json' \
  -H 'X-Admin-Key: adm_demo_change_me' \
  -d '{"provider":"garmin","name":"production-oauth","secret":"replace-me"}'

Production hardening still required

This repository is an MVP, not a compliance certification. Before production, add:

• An external OAuth 2.1 / OIDC authorization server and protected-resource metadata

• Workload identity or signed JWT validation instead of opaque demo bearer keys

• PostgreSQL, schema migrations, backups and tenant-level database controls

• A managed KMS or secret manager instead of application-derived Fernet keys

• Consent and legal-basis records linked to each member and purpose

• Retention, deletion, data-subject request and regional processing workflows

• Signed tool manifests and deployment approvals

• Immutable or tamper-evident audit storage and SIEM export

• Rate limits, circuit breakers, batch limits and human approval services

• Provider-specific OAuth and token refresh handling

• Security testing for prompt injection, tool poisoning, SSRF and confused-deputy attacks

Important design choices

• The model never authorizes itself. Tool and purpose policy is checked by deterministic code.

• Provider credentials never enter MCP tool output or model context.

• Member identifiers are hashed before audit storage.

• Tools return evidence, confidence, limitations and explicit non-diagnostic boundaries.

• Reward and prevention outputs require human review in this MVP. Triggering redeploy to clear Dockerfile validation cache.
