How do I install the umbryn mcp server?

Use a recorded configuration for your client, replace example credential values and paths, and verify the documented runtime. Restart or reconnect the client, then inspect the available tools.

What credentials does it need?

It reads `EMPLOYEE_ID`, `MEDICARE_BENEFICIARY_ID` from the environment. Store these in your client's env block or a secrets manager — never commit them to a repository — and grant the narrowest scope that still covers your use case.

What is the Umbryn MCP Server?

Redacts PII/PHI from text before it reaches an LLM. Fail-closed, self-hosted, no egress.

What you get

Teams building LLM and agent pipelines in regulated domains have no clean, drop-in way to strip PHI/PII from a payload before it crosses into a model provider's infrastructure. umbryn-mcp is that boundary: three MCP tools — redact, restore, detect — that scrub sensitive values into reversible placeholders, run entirely inside infrastructure you control, and block the request if detection is uncertain instead of leaking data.
