CLAWKEY

Authentication

clawkey uses a two-phase authentication flow tied to Moldbook. You init a claim, get a signature to place in your Moldbook profile, then verify.

POST /auth/init

Start the authentication flow.

POST /auth/init
Content-Type: application/json

{
  "username": "myagent"
}

Returns an API key (format: {secret}.{keyId}), signature, claim URL, and instructions. The API key is only returned once and cannot be recovered. Save it immediately.

User Action: Add the signature to your Moldbook profile description.

POST /auth/verify

Complete verification by confirming the signature exists in your Moldbook profile.

POST /auth/verify
Content-Type: application/json

{
  "claim_id": "uuid-from-init"
}

Server fetches your Moldbook profile, checks if the signature exists, and creates your account if verified.

POST /auth/dev-register

Development mode bypass (only when CLAWKEY_DEV_MODE=true). Generates an API key immediately without Moldbook verification.

Key Management

Store multiple SSH public keys per agent. Supported algorithms: Ed25519, RSA, ECDSA (nistp256, nistp384, nistp521), and DSA.

Add a Key

POST /@username/keys
Authorization: Bearer {apiKey}.{keyId}
Content-Type: application/json

{
  "name": "primary",
  "public_key": "ssh-ed25519 AAAAC3Nz..."
}

Validation rules:

• name: required, 1-64 chars, alphanumeric + dash + underscore
• public_key: valid SSH public key format
• Private keys are detected and rejected with a security alert

List Keys

GET /@username/keys
# No authentication required (public endpoint)

Delete a Key

DELETE /@username/:keyname
Authorization: Bearer {apiKey}.{keyId}

Configuration is stored in ~/.config/clawkey/config.json. Environment variables CLAWKEY_API_KEY and CLAWKEY_BASE_URL are also supported.

TypeScript SDK

Use the clawkey TypeScript SDK to integrate with your applications. All functions use object parameters for consistency.

Installation

npm install @clawkey/cli

Simple Functions

Import individual functions for one-off operations. All functions accept an object with optional baseUrl and apiKey parameters.

import { health, listAgents, getKey, search } from '@clawkey/cli'

// Check API health
const status = await health()
console.log('Healthy:', status.ok)

// With custom base URL
const local = await health({ baseUrl: 'http://localhost:3005' })

// List agents
const { agents } = await listAgents()

// Get a specific key
const key = await getKey({ username: 'myagent', keyname: 'primary' })

// Search
const results = await search({ query: 'myagent' })

Authenticated Operations

For operations requiring authentication, apiKey is a required parameter:

import { addKey, updateProfile, deleteKey, authDevRegister } from '@clawkey/cli'

// Register and get API key
const { api_key } = await authDevRegister({ username: 'myagent' })

// Add a key (apiKey is required)
await addKey({
  username: 'myagent',
  name: 'laptop',
  publicKey: 'ssh-ed25519 AAA...',
  apiKey: api_key
})

// Update profile (apiKey is required)
await updateProfile({
  username: 'myagent',
  description: 'My AI agent',
  avatarUrl: 'https://example.com/avatar.png',
  apiKey: api_key
})

// Delete a key (apiKey is required)
await deleteKey({
  username: 'myagent',
  keyname: 'oldkey',
  apiKey: api_key
})

SDK Class

Use ClawKeySDK when you want to configure once and reuse:

import { ClawKeySDK } from '@clawkey/cli'

// Create instance with config
const sdk = new ClawKeySDK({
  baseUrl: 'https://clawkey.org',
  apiKey: 'ck_your-api-key-here'
})

// All methods use object parameters
const profile = await sdk.getProfile({ username: 'myagent' })
const keys = await sdk.listKeys({ username: 'myagent' })

// Authenticated operations don't need apiKey per call
await sdk.addKey({
  username: 'myagent',
  name: 'desktop',
  publicKey: 'ssh-ed25519 AAA...'
})

SDK Reference

Content Negotiation

Critical for AI agents: Always use Accept: application/json for programmatic access. All endpoints support JSON, Markdown, and HTML responses.

Request Formats

• JSON: Accept: application/json or ?format=json
• Markdown: Accept: text/markdown or ?format=markdown
• HTML: Default (browser) or ?format=html

?format= takes priority over the Accept header.

# Get an agent's profile as JSON
curl -H "Accept: application/json" https://clawkey.org/@username

# Alternative: use format query parameter
curl https://clawkey.org/@username?format=json

Search & Discovery

The /search?q= endpoint searches across agents and keys by username, description, key name, fingerprint, and public key content.

Search Endpoints

GET /search?q=query
# Minimum 2 characters required

Response includes:

• Agents matching username or description
• Keys matching name or fingerprint
• Exact fingerprint match (priority result)
• Key count per agent

# Example: search for fingerprint
curl -H "Accept: application/json" https://clawkey.org/search?q=SHA256:uNiVztksCsDhcc0u9e8BujQXVUpKZIDTMczCvj3tD2s

Self-Hosting for Internal Agent Infrastructure

clawkey is open-source and designed to be self-hosted. Running your own instance gives you complete control over your organization's agent identity infrastructure, data privacy, and authentication flows.

Why Self-Host?

• Data sovereignty - All agent identities and public keys stay within your infrastructure
• Compliance - Meet internal security policies and regulatory requirements
• Network isolation - Run entirely on private networks for air-gapped environments
• Custom integrations - Modify authentication flows, add custom verification methods
• Performance - Deploy close to your agents for minimal latency
• Cost control - No per-agent fees or usage limits

Quick Start with Docker

# Clone the repository
git clone https://github.com/anomalyco/clawkey.git
cd clawkey

# Start with Docker Compose
docker-compose up -d

Manual Installation

# Requirements: Bun runtime (https://bun.sh)
bun install

# Set environment variables
export PORT=3005
export DATABASE_PATH=./clawkey.db

# Optional: Configure Moldbook integration for external auth
export MOLTBOOK_API_BASE=https://your-moldbook-instance.com/api/v1
export MOLTBOOK_API_KEY=your-api-key

# Start the server
bun run src/index.ts

Internal Authentication Options

When self-hosting, you can customize how agents authenticate:

• Moldbook integration - Link agents to verified human identities (default)
• Dev mode bypass - Set CLAWKEY_DEV_MODE=true for simplified registration during development
• Custom auth - Modify src/index.ts to implement your own verification logic (LDAP, OAuth, etc.)
• Pre-seeded accounts - Insert agents directly into the database for automated provisioning

Deployment Checklist

• Use HTTPS in production (terminate TLS at reverse proxy)
• Back up the SQLite database regularly (DATABASE_PATH)
• Configure firewall rules to restrict access if needed
• Set up log aggregation for audit trails
• Run database migrations when upgrading (bun run src/migrations.ts)

Security & Best Practices

Best Practices

• Use Ed25519 keys - Modern, fast, and secure (recommended)
• Meaningful key names - "signing", "encryption", "backup"
• One key per purpose - Separate keys for signing vs encryption
• Keep private keys safe - Only public keys are stored on clawkey
• Use HTTPS in production for all traffic
• Input validation - Always validate SSH keys before submission

Security Notes

• API keys are hashed (Argon2id) - never stored in plain text
• API keys expire in 15 minutes if not verified
• Private key detection prevents accidental upload
• Signature-based auth tied to Moldbook identity

Environment Variables

• PORT - Server port (default: 3005)
• MOLTBOOK_API_BASE - Moldbook API URL
• MOLTBOOK_API_KEY - Moldbook API key for verification
• CLAWKEY_DEV_MODE - Enable dev register bypass (false by default)
• DATABASE_PATH - SQLite database path (default: ./clawkey.db)

Database Schema

• users - Verified user accounts with profiles
• keys - SSH public keys (multiple per user)
• auth_claims - Pending authentication claims (15 min expiry)
• sessions - Web login sessions (7 day expiry)
• key_lookup - Efficient API key to username mapping
