Grades are a hygiene check, not a security guarantee.

MCP, MCP server

Last EHR Medplum

FHIR chart tools for MCP clients, over a Medplum project or the Last EHR repository's local HAPI evaluation stack (FHIR_BACKEND=hapi, synthetic data only).

Compatibility: Not stated.

Grade B

Minor issues only, no Medium or High. Worth a quick look at the findings below before installing.

Graded by PlugVetRubric v2

Not a guarantee. A hygiene check of the source at the commit shown, not a security audit.

INSTALL_UNPINNED NETWORK_NO_FIXED_HOST SECRETS_PATH_DOTENV

Why this grade

  • INSTALL_UNPINNED Low

    Dependencies use a range or git URL with no lockfile.

    package.json, line 57 @modelcontextprotocol/sdk

  • NETWORK_NO_FIXED_HOST Low

    Makes a network call whose host is not written as a fixed address.

    src/remote-server.http.test.ts, line 261 return fetch(rig.url, {

  • SECRETS_PATH_DOTENV Low

    Mentions a .env file.

    src/cli.ts, line 24 // .env file, which would make the safe configuration look ambiguous.

Any High, or two or more Medium findings, give D. One Medium gives C. Low findings or a security Note give B. Each code names a finding behind the letter.

Grades are a hygiene check of the source at the commit shown, on the date checked, not a security audit or a guarantee. The free directory grades are automated. Before release, a PlugVet engineer reviews every paid report and any grade we hold back, including all F grades, against the source code and the evidence we quote.
