About quantakrypto pqc-tools
quantakrypto pqc-tools is an open-source post-quantum readiness toolkit for security teams and developers. Its MCP server lets coding agents scan cryptography, inventory findings, and plan migration; the suite also includes CLI, CI, and conformance-testing tools.
Key features
- 01Scan code and infrastructure for vulnerable cryptography
- 02Report readiness scores and compliance evidence
- 03Plan migration and suggest remediation
- 04Test ML-KEM, ML-DSA, and SLH-DSA conformance
Use cases
- 01Audit a codebase before post-quantum migration
- 02Gate new findings in CI workflows
- 03Give coding agents tools to assess readiness
MCP support
The MCP server exposes 16 post-quantum readiness tools to AI coding agents, including scanning, inventory, explanation, migration planning, and remediation. It supports local stdio and hostable HTTP.
Configuration
Remote servers need no local install. Pick your client, then copy the config or install in one click.

Details
From the project READMEquantakrypto-tools
Open-source post-quantum readiness tooling by quantakrypto. Find quantum-vulnerable cryptography in any codebase, wire post-quantum readiness into your editor and your CI, and conformance-test post-quantum implementations — with zero runtime dependencies (Node built-ins only).
Design goals: simple, clean, reusable code; zero runtime dependencies; everything documented, tested, and example-driven.
What's inside
| Tool | What it does | Get it |
|---|---|---|
qScan (@quantakrypto/qscan) | CLI that finds quantum-vulnerable crypto (RSA, (EC)DH, ECDSA, EdDSA, …) across 14 languages (JS/TS, Python, Go, Java/Kotlin/Scala, C#, Rust, Ruby, PHP, Elixir, C/C++, Swift, Objective-C, Dart, Solidity/Move/Cairo) and prints a readiness score. SARIF / JSON / CBOM / evidence (ISO 27001 A.8.24) / OpenVEX output, baselines, incremental & parallel scans. Compliance mandate gate: --mandate cnsa-2.0 / nist-ir-8547 reports each prohibited finding with its dated clause and fails the build on the mandate's deadlines (--lead-months, --fail-now). Opt-in --triage (BYOK LLM re-rank/explain) and a qremediate codemod CLI. | npx @quantakrypto/qscan ./ |
MCP (@quantakrypto/mcp) | Model Context Protocol server that gives AI coding agents post-quantum readiness tools (16 tools — scan, inventory, explain, suggest-hybrid, CBOM, plan-migration, triage, remediate, probe-endpoint, …). Local stdio + hostable HTTP. | claude mcp add quantakrypto npx @quantakrypto/mcp |
Sieve (@quantakrypto/sieve) | Conformance battery for ML-KEM (FIPS 203), ML-DSA (FIPS 204), and SLH-DSA (FIPS 205) implementations, driven over a JSON stdin/stdout protocol. | npx @quantakrypto/sieve --help |
Action (@quantakrypto/action) | GitHub Action that runs the qScan/Sieve/qProbe checks in CI, writes SARIF for code-scanning upload, annotates the diff, and fails the build only on new quantum-vulnerable crypto. | uses: quantakrypto/pqc-tools/packages/action@v1 |
agent (@quantakrypto/agent) | Optional, zero-dependency BYOK (bring-your-own-key) LLM client (native fetch; Anthropic + OpenAI-compatible adapters) that powers qScan --triage and qremediate --llm. Networked, key-holding — kept isolated (see also qProbe). | npm i @quantakrypto/agent |
qProbe (@quantakrypto/qprobe) | Actively probes live TLS/SSH endpoints you own for post-quantum readiness — PQC-hybrid key exchange (X25519MLKEM768) and classical certificate posture. Gated behind an ownership attestation; reports, never modifies ("engine disposes"). See THREAT-MODEL. | npx @quantakrypto/qprobe --i-own-this host |
All of qScan, MCP, the Action, agent, and qProbe share the engine in
@quantakrypto/core (npm i @quantakrypto/core) — detectors,
the vulnerable-dependency DB, the readiness score, SARIF/JSON/CBOM/evidence/OpenVEX
reporting, and the
offline agent-plane primitives (context redactor, verify_fix gate, codemods, patch
policy). Sieve is standalone: it tests other implementations and implements no
crypto itself.
Infrastructure coverage. Beyond application source, the shared core engine
carries config-scope detectors for Terraform/OpenTofu IaC and cloud KMS, JSON
Web Keys, Kubernetes / cert-manager / Istio, CI/CD artifact & code signing
(cosign/GPG/jarsigner/codesign/minisign), secrets at rest (SOPS/age, PGP, Sealed
Secrets), message brokers (Kafka/MQTT), databases (pgcrypto, libpq sslmode), and
JOSE/JWE key management — so qscan, the Action, and MCP flag infrastructure
crypto with no extra install. qProbe adds the live-endpoint dimension (see the
table above). The narrative anchor for infrastructure is harvest now, decrypt
later: data and secrets captured today are decryptable once a CRQC exists.
Quick start
# 1. Scan a codebase for quantum-vulnerable cryptography.
npx @quantakrypto/qscan ./
# 2. Give your AI coding agent post-quantum readiness tools.
claude mcp add quantakrypto npx @quantakrypto/mcp
# 3. Conformance-test a post-quantum implementation (adapter speaks the JSON protocol).
npx @quantakrypto/sieve --impl "node ./my-impl.js" --param ml-kem-768
# 4. Gate against a compliance mandate's dated deadlines (CNSA 2.0 / NIST IR 8547).
# Verdicts also ride in --format json/sarif/evidence; --policy lets an org
# acknowledge families it is knowingly migrating (exempt from early gating).
npx @quantakrypto/qscan ./ --mandate cnsa-2.0 [--policy .quantakrypto/crypto-policy.json]
Add the CI gate by dropping
packages/action/examples/quantum-readiness.yml
into .github/workflows/, or wire it up directly:
- uses: quantakrypto/pqc-tools/packages/action@v1
with:
path: "."
severity-threshold: "high"
Each package README has the full options reference and more examples: qScan · MCP · Sieve · Action · core · agent.
Using quantakrypto alongside a PQC library (liboqs / OQS)
quantakrypto does not implement post-quantum cryptography, by design — it is
the scanner, the CI gate, and the conformance harness you wrap around a real PQC
library like liboqs / Open Quantum Safe. They
compose: quantakrypto finds and gates classical crypto (qscan, the Action),
tells you what to migrate to and in what order (qscan --tier, MCP
plan_migration, qremediate), and conformance-tests the replacement
(sieve runs any ML-KEM/ML-DSA/SLH-DSA implementation against FIPS 203/204/205,
with exact-value KATs when you supply official NIST ACVP vectors). liboqs
supplies the primitives.
See the worked end-to-end walkthrough — scan → migrate → verify → gate — in
examples/liboqs-migration/.

Development
Requires Node ≥ 20.
npm install # links the workspaces
npm run build # tsc --build (project references)
npm test # node:test across all packages
The toolchain is intentionally tiny: TypeScript + tsx (to run node:test on
.ts) are the only dev dependencies; there are no runtime dependencies.
Documentation & compliance
Full documentation lives in docs/:
- Objectives & scope — what the toolchain is for, what each library does, the load-bearing decisions, and the deliberate scope boundaries. Start here.
- Architecture decisions — the immutable "why" behind each load-bearing choice (zero deps, shared core contract, two-plane agent, …).
- Standards & compliance — what the tools touch and could align to: NIST FIPS 203/204/205, SP 800-208, CNSA 2.0, SARIF, CWE, ISO/IEC 27001 (A.8.24), Common Criteria, FIPS 140-3, EU DORA/NIS2, US M-23-02 / NSM-10, and OSS assurance (SLSA, OpenSSF Scorecard, SPDX/REUSE).

New to MCP?
From what the protocol is to installing your first server, these answers cover most first questions.
An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
