Natural Language, Real Actions

Just describe what you want. The MCP server translates your intent into QuantumAPI calls.

Store a Secret

prompt

// Ask your AI assistant:

"Create a secret called DATABASE_URL

with value postgres://user:pass@host/db"

>Secret created: { id: "s-1a2b...", name: "DATABASE_URL" }

Generate a Key

prompt

// Ask your AI assistant:

"Generate an ML-DSA-65 signing key

named release-signing-2026"

>{ id: "k-3c4d...", algorithm: "ML-DSA-65", status: "active" }

Encrypt Data

prompt

// Ask your AI assistant:

"Encrypt this token: sk-abc123..."

>{ ciphertext: "UsBU+Q4k9x...", algorithm: "ML-KEM-768" }

Check Usage

prompt

// Ask your AI assistant:

"Show my current API usage and costs"

>{ apiCalls: 12430, costs: { total: 4.21 } }

13 Tools, One Server

Secrets Management

List, create, update, and delete secrets. Values are always redacted — never sent to the LLM.

Key Management

Generate, rotate, and inspect post-quantum and classical cryptographic keys.

Encrypt & Decrypt

Encrypt and decrypt data with ML-KEM-768 or AES-256-GCM from a single prompt.

Health Check

Verify platform status, version, and uptime from your IDE.

Usage & Billing

Monitor API calls, storage, and costs without leaving your workflow.

Security by Design

Secret values and key material are never returned. API key via env var only.
