Qualys MCP

A Model Context Protocol server for full Qualys portal management — expose VMDR, Policy Compliance, WAS, Cloud Agent, Container Security, TotalCloud, Patch Management, CSAM/GAV, EASM and administration to any MCP‑capable client (Claude, and other MCP hosts).

One process per Qualys console (run as many as you have subscriptions). Built on FastMCP, with a single client that speaks all three Qualys API families, a strict read / write / destructive safety model, and credentials that never touch chat or plaintext.

---

Highlights

• Broad coverage — 59 auto‑discovered feature modules spanning the whole portal: VMDR, PC, WAS, Cloud Agent, Container Security, TotalCloud/CloudView, Patch Management, CSAM/GAV, EASM, FIM, EDR, PCRS, and administration.
• ~400 tools — list_hosts, list_host_detections, launch_scan, search_was_findings, list_knowledgebase, get_cs_image_vulnerabilities, and hundreds more, each mapped 1:1 to a documented Qualys API operation.
• Three API regimes, one client — the classic "FO" XML API, the QPS REST API, and the JWT‑authenticated Gateway are all handled behind self._fo / self._qps / self._gateway.
• Safety tiers are load‑bearing — every tool is annotated read‑only, write, or destructive. Destructive tools (delete / purge / deactivate) are not even registered unless you opt in per console, and still require a per‑call confirmation token.
• Lazy auth — no network calls at import or construction; --check runs fully offline with no credentials.
• Secrets stay secret — on Windows, credentials live only in DPAPI‑encrypted blobs; on any OS you can supply them via environment variables. Nothing is ever written to the repo.

The three API regimes

Regime	Base path	Auth	Payload
Classic "FO"	/api/2.0/fo/, /msp/	Basic + X-Requested-With header	form → XML
QPS REST	/qps/rest/	Basic	XML <ServiceRequest> / JSON
Gateway	gateway.<pod>.apps.qualys.com	Bearer JWT (from /auth)	JSON

Architecture

qualys_mcp/
  server.py     FastMCP server; lazy auth; --check offline validation
  registry.py   auto-discovers modules/*.py
  client.py     one client, three API regimes (FO / QPS / Gateway-JWT)
  config.py     per-console config + platform (POD) -> URL map
  common/       auth (HTTP mw), errors, logging, rate_limit, utils, xml
  modules/      base.py + one file per feature module (the bulk of the surface)

Adding a capability is just dropping a file in qualys_mcp/modules/ — see docs/MODULE_BUILD_GUIDE.md.

Quick start

1. Install

python -m venv .venv
# Windows:      .\.venv\Scripts\pip install -e .
# macOS/Linux:  ./.venv/bin/pip install -e .

2. Offline sanity check (no credentials required)

python -m qualys_mcp --check

Lists every discovered module with its tool count and exits — a good first smoke test.

3. Provide credentials

You need a Qualys API user and your platform/POD code (e.g. US1, US2, EU1; find it under your console URL or Help → About).

Any OS — environment variables:

export QUALYS_USERNAME='api-user'
export QUALYS_PASSWORD='api-pass'
export QUALYS_PLATFORM='US2'          # or set QUALYS_API_URL / QUALYS_GATEWAY_URL
python -m qualys_mcp --transport streamable-http --host 127.0.0.1 --port 8781 --console-label consulting

Windows — DPAPI‑encrypted blobs (recommended for a persistent deployment):

# Encrypt once per console; the blob is user-scoped and stored under .secrets/
.\encrypt-qualys-creds.ps1 -Console consulting -Platform US2
.\encrypt-qualys-creds.ps1 -Console cloud      -Platform US2

# Launch one instance per console (:8781, :8782)
.\start-qualys-mcp.ps1
#   ...opt into destructive tools for a console only when you mean it:
.\start-qualys-mcp.ps1 -EnableDestructive cloud

# Optional: keep both alive across reboots via a Scheduled Task watchdog
.\register-qualys-mcp-task.ps1

See .env.example for every QUALYS_* setting.

4. Point your MCP client at it

A ready‑to‑use .mcp.json is included for Claude Code:

{
  "mcpServers": {
    "qualys-consulting": { "type": "http", "url": "http://localhost:8781/mcp" },
    "qualys-cloud":      { "type": "http", "url": "http://localhost:8782/mcp" }
  }
}

scripts/register_mcp_clients.py shows how to register the same local‑HTTP servers into several MCP clients at once.

Safety model

• Tools are annotated read‑only, write, or destructive.
• Destructive tools (delete, purge, deactivate, uninstall) are not registered unless the console runs with QUALYS_ENABLE_DESTRUCTIVE=true.
• Even when enabled, each destructive tool requires a matching confirm=<id> argument before it will act — so a destructive call can never happen by accident from a single prompt.

Read docs/SAFETY_AUDIT.md for the full tiering.

Module & tool inventory

• 59 modules auto‑discovered from qualys_mcp/modules/.
• ~360 tools registered by default; ~400 with QUALYS_ENABLE_DESTRUCTIVE=true (the extra ~40 are the guarded destructive tools that otherwise stay hidden).
• Spread across the three API regimes, with a handful of modules spanning two.

The full per‑module table (registry name, API family, tool counts, one‑line description) is in docs/MODULE_INDEX.md, and a complete endpoint → tool → action breakdown is in docs/ENDPOINTS_TOOLS_ACTIONS.md.

Configuration reference

Variable	Purpose
QUALYS_USERNAME / QUALYS_PASSWORD	API user credentials
QUALYS_PLATFORM	POD code (US1…KSA1) — auto‑fills API + Gateway URLs
QUALYS_API_URL / QUALYS_GATEWAY_URL	Explicit overrides for unlisted PODs
QUALYS_CONSOLE_LABEL	Names the console in logs and the server name
QUALYS_ENABLE_DESTRUCTIVE	true to register the destructive tier
QUALYS_MCP_MODULES	Comma‑separated allowlist to scope a console to its licensed modules
QUALYS_MCP_API_KEY	Optional shared secret for the HTTP transport

Development

pip install -e ".[dev]"
python -m qualys_mcp --check   # offline validation
pytest                          # unit tests (no network)
ruff check .                    # lint
