Mcp Osv — independently scanned and version-tracked by SaferSkills.
SaferSkills independently audited Mcp Osv (Agent Skill) and scored it 100/100 (green). The audit ran 55 deterministic rules across Security, Supply Chain, Maintenance, Transparency, and Community; it found 0 high-severity and 0 lower-severity findings. The full rule-by-rule trace and per-finding evidence are below. Free, methodology-open.

OSV.dev (Open Source Vulnerabilities) MCP.
Part of Pipeworx — an MCP gateway connecting AI agents to 1856+ live data sources. This is an independent, unofficial integration — not affiliated with, endorsed by, or published by the upstream provider.
| Tool | Description |
|---|---|
query_package_vulns | Find all known vulnerabilities for an open-source package, optionally at a specific version, via the OSV.dev database. Omit version to get every vuln known for the package. Returns a compact summary array (id, summary, aliases, severity, references). Keyless. |
get_vulnerability | Get full detail for a single vulnerability by its OSV ID — e.g. "GHSA-jf85-cpcp-j695", "CVE-2021-23337", "PYSEC-2021-XXX". Returns summary, details, aliases, severity, affected packages/ranges, and references. Keyless. |
query_by_commit | Find vulnerabilities affecting a specific source-repository git commit via OSV.dev. Useful when you have a pinned commit hash rather than a released version. Returns the same compact vuln summary array. Keyless. |
query_batch | Batch vulnerability query against OSV.dev (up to 1000 entries per call) — for SBOM-style "scan every dependency in this lockfile" workflows. Pass an array of {package:{name,ecosystem}, version?} or {commit} entries. Returns the vuln IDs matched per query (use get_vulnerability for full detail per ID). Keyless. |
Add to your MCP client (Claude Desktop, Cursor, Windsurf, etc.):
{
"mcpServers": {
"osv": {
"url": "https://gateway.pipeworx.io/osv/mcp"
}
}
}tools/list at https://gateway.pipeworx.io/osv/mcp returns the tools in the table above plus the shared Pipeworx meta-tools — ask_pipeworx, discover_tools, search_within, remember/recall and the rest of the gateway-wide set. So the tool count you see is larger than this table: a single-pack endpoint currently lists roughly 30 shared tools alongside the pack's own. The connection's initialize response states its exact scope, and is the authoritative answer for a given day.
This is deliberate, not multiplexing by accident. The meta-tools are what let a scoped connection answer a question this pack does not cover — via ask_pipeworx, which routes across the whole catalog — without you adding a second MCP server. There is currently no way to mount a pack endpoint without them; if the extra schemas cost you more context than the routing is worth, connect to the full gateway once rather than to several pack endpoints.
Or connect to the full Pipeworx gateway to get every pack's tools listed directly, instead of just this one's:
{
"mcpServers": {
"pipeworx": {
"url": "https://gateway.pipeworx.io/mcp"
}
}
}Both URLs reach the same gateway and the same 1856+ data sources. The only difference is which pack's tools are listed directly; ask_pipeworx reaches all of them from either one.
curl -X POST https://gateway.pipeworx.io/v1/tools/query_package_vulns \
-H 'Content-Type: application/json' \
-d '{"name":"lodash","ecosystem":"npm"}'No account needed for the first calls. Inspect any tool: GET https://gateway.pipeworx.io/v1/tools/query_package_vulns. Find one: POST https://gateway.pipeworx.io/v1/tools/search_packs with {"query":"..."}.
This package also runs as a local stdio MCP server — no Pipeworx account, no gateway round-trip:
{
"mcpServers": {
"osv": {
"command": "npx",
"args": ["-y", "@pipeworx/mcp-osv"]
}
}
}Or run it directly to confirm it starts:
npx -y @pipeworx/mcp-osvIt speaks MCP over stdin/stdout and answers initialize/tools/list/tools/call for only this pack's tools — none of the shared meta-tools the gateway connection above adds. Same source, same tools, no ask_pipeworx routing.
Instead of calling tools directly, you can ask questions in plain English — this works on the pack endpoint above as well as on the full gateway:
ask_pipeworx({ question: "your question about Osv data" })The gateway picks the right tool and fills the arguments automatically.
