概要

Kamy — the document layer for AI-native software

Tagline: Generate, sign, prove. One API.

Kamy is one developer-first MCP for the full document chain: generate, sign, edit, verify, audit. Render PDFs from templates, sign them with PAdES B-LT cryptographic signatures (own CA + RFC 3161 timestamps + embedded CRL), edit / fill / redact existing PDFs, and produce a tamper-evident audit trail anyone can verify at https://kamy.dev/verify — no Kamy account required.

Replaces the typical stitched stack of DocuSign + a PDF generation API + a homegrown audit logger with one vendor, one API, one audit boundary.

Tools exposed

Tool	What it does
`render_pdf`	Render a PDF from a template (invoice, contract, certificate, etc.) or raw HTML/CSS. Returns a signed URL valid for 1 hour plus persistent retrieval.
`sign_pdf`	Apply a PAdES B-LT cryptographic seal. Own CA + RFC 3161 timestamp + embedded CRL. Returns a public verify URL.
`edit_pdf`	Fill AcroForm widgets, stamp text or signature images, redact PII regions on existing PDFs.
`verify_pdf`	Verify any Kamy-signed PDF. Returns cert chain, timestamp, byte range, audit row, tamper-evidence boolean.
`list_templates`	List system templates + your custom ones, filterable by tag.
`install_sdk`	Print install commands for the TypeScript / Python SDK.
`ask_kamy`	Query the Kamy docs in natural language.

Install

For Claude Code:

claude mcp add --transport http kamy https://mcp.kamy.dev/mcp
For Cursor, add to ~/.cursor/mcp.json:

{
  "mcpServers": {
    "kamy": {
      "url": "https://mcp.kamy.dev/mcp",
      "transport": "streamable-http",
      "env": {
        "KAMY_API_KEY": "<YOUR_KAMY_API_KEY>"
      }
    }
  }
}
Get a free API key at kamy.dev/dashboard/api-keys (no credit card, 100 renders/month included).

Canonical flow: generate → sign → prove
import { kamy } from "@kamydev/sdk";

// 1. Generate
const doc = await kamy.documents.render({
  template: "invoice",
  data: { invoiceNumber: "INV-001", lineItems: [...] },
});

// 2. Sign with PAdES B-LT (recipient-verifiable, audit-trailed)
const signed = await kamy.signatures.signWithPki({ renderId: doc.id });

// 3. Anyone verifies the document independently — no Kamy account
console.log(signed.verify_url);
// → https://kamy.dev/verify/<sha256>
Use cases
AI agents that produce documents. Your agent issued a refund, signed a contract, approved a release. Every action gets a tamper-evident, third-party-verifiable receipt. When the customer disputes, when the auditor asks, when the regulator knocks — you have evidence, not log files.

Compliance-grade SaaS. Your fintech / healthtech / regtech app needs PDFs that pass legal review without a separate post-processor. Render PDF/A, sign with cryptographic certs, archive with hash anchoring, retrieve on demand. SOC 2 evidence on autopilot.

Embedded document workflows. Your customers need contracts, invoices, receipts inside your product. Embed them. White-label brand kits, customer-owned audit trails, embeddable verify widgets.

What makes the verify path different
Every signed Kamy document is independently verifiable forever, by anyone, without trusting Kamy. The PAdES signature chains to a CA, the timestamp chains to FreeTSA, the audit row chains to a public hash. We're a layer; we shouldn't be a single point of trust.

Try the verify widget at https://kamy.dev/verify — drag any signed Kamy PDF in.

invoice · receipt · quote · contract · agreement · certificate · shipping-label · report
