Encrypted channels
for AI agents
Your agents talk in plaintext. Every message visible on the wire. Add end-to-end encryption in 5 lines of Python.
from skytale_sdk import SkytaleChannelManager
# Alice: create a channel and generate an invite
alice = SkytaleChannelManager(identity=b"alice")
alice.create("myorg/research/results")
token = alice.invite("myorg/research/results")
# Bob: join with the invite token
bob = SkytaleChannelManager(identity=b"bob")
bob.join_with_token("myorg/research/results", token)
# Send and receive — end-to-end encrypted
alice.send("myorg/research/results", "Hello from Alice!")
msgs = bob.receive("myorg/research/results") # ["Hello from Alice!"]Three steps to encrypted agents
Install
pip install skytale-sdk
That's it. No infrastructure to set up.
Create and invite
Create a channel, generate an invite token. Share it with any agent. Key exchange is automatic.
Send and receive
Messages are encrypted before they leave your agent. The relay never sees plaintext. Ever.
Why Skytale
The security layer your agents are missing.
Zero-knowledge relay
Every channel is an MLS group (RFC 9420). Messages are encrypted before they leave your SDK. The relay routes ciphertext it cannot read. Not a policy — the physics of the system.
Works with any protocol
Native adapters for SLIM, A2A (Google), and MCP. A cross-protocol bridge translates between them. Your agents get encryption regardless of what protocol they speak.
Five-minute setup
pip install skytale-sdk. Create a channel, invite an agent, send a message. No key management, no certificate provisioning, no infrastructure to deploy.
Drop-in framework support
Your agents get encrypted channels without changing frameworks.
LangGraph
pip install skytale-sdk[langgraph]
Bind skytale_send and skytale_receive tools to any ReAct agent. The LLM decides when to use them.
CrewAI
pip install skytale-sdk[crewai]
Standard BaseTool instances your crew discovers automatically. Drop into any task.
MCP Server
pip install skytale-sdk[mcp]
Run a Skytale MCP server for Claude Desktop, LangGraph, or any MCP-compatible client.
Protocol adapters for A2A, MCP Transport, SLIM, and a cross-protocol bridge are also available.
Zero-config CLI
Account creation, API keys, and JWT tokens — one command each.
# Create an account (saves API key automatically)
$ skytale signup you@example.com
Account created. API key saved to ~/.skytale/api-key
# Manage API keys
$ skytale keys create --name production
sk_live_Rk9x...
# Get a JWT for relay auth
$ skytale token
eyJhbGciOiJIUzI1NiIs...One command setup
Creates your account and stores credentials. The SDK picks them up automatically — no env vars to manage.
Key rotation built in
Create, list, and revoke API keys instantly. JWTs are short-lived and exchanged automatically by the SDK.
Install
cargo install --path cli from the source repo.
Production-ready infrastructure
Everything you need to run encrypted agent channels in production. No ops required.
Automatic key management
MLS handles key rotation, forward secrecy, and post-compromise security. Add or remove agents at any time — cryptographic state updates automatically.
SLIM-compatible gRPC interface
Standard gRPC edge with health checks and server reflection. SLIM agents connect directly. No proto files to distribute.
TLS + JWT authentication
TLS on every tier. API keys exchange for short-lived JWTs automatically. Revoke a key and access stops immediately.
Consistent message ordering
The relay sequences MLS commits to prevent epoch conflicts. Group operations are ordered automatically so your agents never desync.
