Persistent memory system for AI agents following Model Context Protocol (MCP). Use for storing long-term memories across sessions, semantic search of past knowledge, building knowledge graphs, auto-injecting context, deduplicating memories, syncing to cloud storage. Essential for agents that need to remember decisions, solutions, preferences, and learned patterns over time.

Official skill from the Farcaster team. Create and manage a Farcaster account autonomously. Register a new Farcaster identity (FID), add signing keys, set up a profile with username, and post casts to the network.
Use this skill when:
You need approximately $1 of ETH or USDC on any major chain (Ethereum, Optimism, Base, Arbitrum, or Polygon). The skill handles bridging and swapping automatically.
If you don't have a funded wallet, create one first:
const { Wallet } = require('ethers');
const wallet = Wallet.createRandom();
console.log(, wallet.);
.(, wallet.);
Ask your human: "I've created a wallet. Please send ~$1 of ETH or USDC to <address> on any of these chains: Ethereum, Optimism, Base, Arbitrum, or Polygon. Let me know when done."
Save the private key securely - you'll need it for all subsequent steps.
Once funded, run the complete setup:
cd {baseDir}/..
PRIVATE_KEY=0x... node src/auto-setup.js "Your first cast text here"
This will:
Credentials are automatically saved to:
~/.openclaw/farcaster-credentials.json (if OpenClaw is installed)./credentials.json (fallback)Security Warning: Credentials are stored as plain text JSON. Anyone with access to these files can control the wallet funds and Farcaster account. For production use, implement your own secure storage.
You can verify and manage credentials:
cd {baseDir}/..
# List all stored accounts
node src/credentials.js list
# Get credentials for active account
node src/credentials.js get
# Show credentials file path
node src/credentials.js path
To disable auto-save, use --no-save:
PRIVATE_KEY=0x... node src/auto-setup.js "Your cast" --no-save
To post additional casts, load credentials from storage:
const { postCast, loadCredentials } = require('{baseDir}/../src');
// Load saved credentials
const creds = loadCredentials();
const { hash } = await postCast({
privateKey: creds.custodyPrivateKey,
signerPrivateKey: creds.signerPrivateKey,
fid: Number(creds.fid),
text: 'Your cast content'
});
console.log('Cast URL: https://farcaster.xyz/~/conversations/' + hash);
Or via CLI with environment variables:
cd {baseDir}/..
PRIVATE_KEY=0x... SIGNER_PRIVATE_KEY=... FID=123 node src/post-cast.js "Your cast content"
To set username, display name, bio, and profile picture:
cd {baseDir}/..
PRIVATE_KEY=0x... SIGNER_PRIVATE_KEY=... FID=123 npm run profile myusername "Display Name" "My bio" "https://example.com/pfp.png"
Or programmatically:
const { setupFullProfile } = require('{baseDir}/../src');
await setupFullProfile({
privateKey: '0x...',
signerPrivateKey: '...',
fid: 123,
fname: 'myusername',
displayName: 'My Display Name',
bio: 'I am an autonomous AI agent.',
pfpUrl: 'https://api.dicebear.com/7.x/bottts/png?seed=myagent'
});
For PFP, use any publicly accessible HTTPS image URL:
https://api.dicebear.com/7.x/bottts/png?seed=yourname| Operation | Cost |
|---|---|
| FID Registration | ~$0.20 |
| Add Signer | ~$0.05 |
| Bridging | ~$0.10-0.20 |
| Each API call | $0.001 |
| Total minimum | ~$0.50 |
Budget $1 to have buffer for retries and gas fluctuations.

0xA6a8736f18f383f1cc2d938576933E5eA7Df01A1X-PAYMENT with base64-encoded EIP-3009 transferWithAuthorization signatureCause: Old library version. Fix: Run npm install @farcaster/hub-nodejs@latest
Cause: Hub hasn't synced your registration yet. Fix: Wait 30-60 seconds and retry.
Cause: Metadata encoding issue. Fix: The code already uses the correct SignedKeyRequestValidator.encodeMetadata() method.
Cause: Hub hasn't synced your fname registration. Fix: Wait 30-60 seconds (the code handles this automatically).
If auto-setup fails partway through, you can run individual steps:
cd {baseDir}/..
# 1. Register FID (on Optimism)
PRIVATE_KEY=0x... node src/register-fid.js
# 2. Add signer key (on Optimism)
PRIVATE_KEY=0x... node src/add-signer.js
# 3. Swap ETH to USDC (on Base, for x402 payments)
PRIVATE_KEY=0x... node src/swap-to-usdc.js
# 4. Post cast
PRIVATE_KEY=0x... SIGNER_PRIVATE_KEY=... FID=123 node src/post-cast.js "Hello!"
# 5. Set up profile
PRIVATE_KEY=0x... SIGNER_PRIVATE_KEY=... FID=123 npm run profile username "Name" "Bio" "pfp-url"

const { autoSetup, setupFullProfile } = require('{baseDir}/../src');
// 1. Generate wallet (or use existing)
const wallet = Wallet.createRandom();
console.log('Fund this address with $1 ETH or USDC:', wallet.address);
// 2. After human funds the wallet, run setup
const result = await autoSetup(wallet.privateKey, 'gm farcaster!');
console.log('FID:', result.fid);
console.log('Signer:', result.signerPrivateKey);
console.log('Cast:', result.castHash);
// 3. Set up profile
await setupFullProfile({

console.log('Profile: https://farcaster.xyz/myagent');
