MCP, MCP server
Package Intel
A pay-per-call API selling npm, PyPI and crates.io (Rust) package health, dependency-graph, and vulnerability data to AI coding agents over the x402 payment protocol — plus an MCP server so agents in Claude Desktop/Cursor can call it an
Compatibility: Not stated.
Grade B
Minor issues only, no Medium or High. Worth a quick look at the findings below before installing.
Not a guarantee. A hygiene check of the source at the commit shown, not a security audit.
NETWORK_NO_FIXED_HOST NETWORK_UNNAMED_HOST SECRETS_PATH_DOTENV SECRETS_ENV_READ
Why this grade
- NETWORK_NO_FIXED_HOST Low
Makes a network call whose host is not written as a fixed address.
action/index.mjs, line 81
const snapRes = await fetch(url("/v1/package"), { headers: { accept: "application/json" } }); - NETWORK_UNNAMED_HOST Low
Calls a fixed host that the description does not name.
action/index.mjs, line 81
const snapRes = await fetch(url("/v1/package"), { headers: { accept: "application/json" } }); - SECRETS_PATH_DOTENV Low
Mentions a .env file.
mcp-client/src/server.ts, line 25
if (existsSync(".env")) process.loadEnvFile(".env"); - SECRETS_ENV_READ Note
Reads an environment variable whose name contains KEY, SECRET, TOKEN, PASSWORD or CREDENTIAL.
mcp-client/src/server.ts, line 42
const privateKey = process.env.X402_PRIVATE_KEY;
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.
