Oxiploitability

oxiploitability-mcp

Oxiploitability is a Rust MCP server for sourced CVE research. It combines NVD vulnerability records, FIRST EPSS probabilities, CISA KEV entries, OSV package advisories, CVE.org records and a public proof-of-concept index. It can also check supported SBOMs, lockfiles, project directories and container images.

This product uses the NVD API but is not endorsed or certified by NVD. EPSS is published by FIRST, KEV by CISA, package advisories by OSV.dev, CVE records by CVE.org and public proof-of-concept links by the nomi-sec/PoC-in-GitHub index.

mcp-name: io.github.abelreqma/oxiploitability-mcp

Tools

Findings name their source and link to its record. nvd-cpe, cve.org-cna and osv:* identify product or package evidence; nvd-description is a lead with confirmed: false. A missing score, KEV entry or PoC is not evidence that a vulnerability is safe or unexploited. Check partial, warnings, needs_verification and not_checked before relying on an answer.

Lookup tools do not write local files. scan_sbom creates a new report without replacing an existing one; an image scan may pull the image through Trivy or Syft if installed. See PRIVACY.md for outbound data and local files.

Install from a checkout

From this repository, install the native executable with:

cargo install --path . --locked

The executable is normally ~/.cargo/bin/oxiploitability. Rust builds native executables for each operating system and CPU architecture, so use a matching build and its full path in desktop client settings; desktop apps may not inherit your shell's PATH.

An NVD API key is optional. Set NVD_API in the private environment of a CLI client if you have one; do not commit a key to this repository. Without a key, the server uses NVD's lower request limit.

Configure a client

Claude Desktop on macOS

Add this entry to mcpServers in ~/Library/Application Support/Claude/claude_desktop_config.json, preserving other servers, and restart Claude Desktop when convenient:

{
  "mcpServers": {
    "oxiploitability": {
      "command": "/absolute/path/to/oxiploitability",
      "args": []
    }
  }
}

The optional NVD key field in the packaged MCPB extension has a known Claude Desktop delivery issue for some binary servers. A keyless setup works without it. Release bundles can also be installed as platform-specific .mcpb files through Settings > Extensions > Advanced settings > Install Extension.

Claude Code

claude mcp add --transport stdio --scope user oxiploitability -- /absolute/path/to/oxiploitability

Codex CLI

codex mcp add oxiploitability -- /absolute/path/to/oxiploitability

Start a fresh Codex chat after adding the server. If you edit ~/.codex/config.toml instead, use [mcp_servers.oxiploitability] with command = "/absolute/path/to/oxiploitability".

Hermes Agent

Merge this entry under mcp_servers in ~/.hermes/config.yaml:

mcp_servers:
  oxiploitability:
    command: /absolute/path/to/oxiploitability

Run hermes mcp test oxiploitability to check discovery. In an existing Hermes chat, use /reload-mcp after changing the config.

Development and release

cargo fmt --check
cargo clippy --all-targets --locked -- -D warnings
cargo test --locked
python3 -m unittest discover -s mcpb -p 'test_*.py'

Tests use local mock HTTP responses. CI builds the macOS, Linux and Windows bundles before release. To publish, create a v* tag and manually run gh workflow run release.yml --ref vX.Y.Z for that tag; the workflow verifies the staged assets before publishing to crates.io and the MCP Registry. Do not run it until the client installations have been checked.
