NETWORK_NO_FIXED_HOST NETWORK_UNNAMED_HOST SECRETS_PATH_DOTENV SECRETS_ENV_READ OBFUSCATION_FILE_OVER_READ_CAP OBFUSCATION_FILE_CAP_REACHED

Why this grade

  • NETWORK_NO_FIXED_HOST Low

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

    packages/api/src/model-router/embed-client.ts, line 109 const resp = await fetch(`${this.url}/embed`, {

  • NETWORK_UNNAMED_HOST Low

    Calls a fixed host that the description does not name.

    packages/api/src/model-router/embed-client.ts, line 109 const resp = await fetch(`${this.url}/embed`, {

  • SECRETS_PATH_DOTENV Low

    Mentions a .env file.

    packages/api/src/db/neo4j.ts, line 3 // Server-side, loopback bolt (NEO4J_URL/USER/PASSWORD in .env). The methodist

  • SECRETS_ENV_READ Note

    Reads an environment variable whose name contains KEY, SECRET, TOKEN, PASSWORD or CREDENTIAL.

    packages/api/src/db/backfill-qdrant-versioning.ts, line 19 ...(process.env.QDRANT_API_KEY ? { apiKey: process.env.QDRANT_API_KEY } : {}),

  • OBFUSCATION_FILE_OVER_READ_CAP Note

    A file was over the read cap and was not fully read.

    packages/mcp/src/profiles/methodist-v2/assets/content.ts, line 1 // AUTO-GENERATED by gen-content.mjs from source/{methodology,door_prompts,record_schemas}.

  • OBFUSCATION_FILE_CAP_REACHED Note

    The 400 file cap was reached before every file was read.

    packages/mcp/src/profiles/methodist-v2/assets/content.ts, line 1 // AUTO-GENERATED by gen-content.mjs from source/{methodology,door_prompts,record_schemas}.

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.

What was checked

Plain notes from the hygiene checks.

  • Permissions

    Pass

    No shell or command execution found, and no extra permission was declared.

  • Install and update

    Pass

    No install-time script found, and dependencies are pinned or absent.

  • Network

    Concern

    can reach a host that is not written as a fixed address. can reach oauth2.googleapis.com. The description does not name that host. can reach openrouter.ai. The description does not name that host. can reach api.github.com. The description does not name that host.
