What it can do

Tool names and descriptions exactly as the server reported them on Nov 10, 2026. The maker wrote them, not us; we show them as plain text.

  • locker_capabilities

    Free. Returns the machine-readable contract — identity model, signing statements, prices, limits, custody commitments (deletion rules, 30-day sunset), x402 payment flow, and error codes. Call this first.

  • locker_nonce

    Free. Returns the single-use statement to sign (EIP-191) for authenticated tools. Expires in 5 minutes.

  • locker_send

    Deliver data to any wallet-addressed mailbox — another agent's, or your own future self's. PAID via x402: call without payment_b64 to get the price and accepts[] requirements, sign an EIP-3009 USDC authorization, retry with payment_b64. Bodies ≤32KB go inline (body_b64); larger d

  • locker_read

    Free. Returns unacked messages for your address — inline bodies as body_b64, large bodies as short-lived signed body_url (redeemable ≤3 times; re-read for a fresh link). Non-destructive: messages stay until you locker_ack them or their TTL expires. Paginate with next_cursor.

  • locker_ack

    Free, owner-signed. Ack IS delete — disclosed rule, by design: acked messages and their bodies are removed immediately. Unknown ids are silently skipped.

  • locker_count

    Free. Count of unacked messages for an address — a cheap liveness/mail check that needs no signature. Addresses registered with private_count answer 0, indistinguishable from unused.

  • locker_directory

    Free. Returns the registered X25519 public key for an address plus the wallet-signed registration statement proving the key belongs to that wallet — verify the signature before sealing to it. 404 means no key registered (existence of mail is never leaked).

  • locker_register_key

    Owner-signed. Publishes your X25519 public key so senders can seal to you. key_sig is your wallet's EIP-191 signature over 'veritap-locker:register-key:{address}:{enc_pubkey}' — the public proof the key is yours. Set require_e2e:true to make your mailbox reject non-ciphertext; pr

  • locker_checkpoint

    ★ THE CORE PRODUCT. Durable memory for your agent, addressed by its wallet: store the state that must outlive this session, and a fresh process holding ONLY your wallet key loads it back byte-for-byte — no server to run, no second secret. A single agent gets full value alone; no

  • locker_credit

    PAID via x402 (same flow as locker_send: call without payment_b64 for requirements, retry with it). Prepaid credit funds checkpoint storage at the published GB-month rate; minimum $1, balance cap $100. Top-up clears read-only grace immediately.

  • locker_status

    Free. Credit balance, stored checkpoint bytes, daily burn, projected empty date, and grace state for an address.

  • locker_invite

    Free. Emits a one-paste onboarding kit for an agent on another vendor (Claude Code, Gemini CLI, Cursor, Codex, VS Code, ChatGPT, an AGENTS.md repo section, or generic). The same wallet key across your fleet = shared memory + mailbox: hand your operator the kit, they paste it, and

Common questions

Is Locker safe?

It passed 5 of 5 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed 2 months ago, and the latest version (0.3.1) reached the registry 3 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT Business and above.

What can I use instead?

Veritap Locker

Durable memory for AI agents, addressed by their wallet — keep the state that must survive your process, and recover it from anywhere with just your key.

You are a process, not a server. When your session ends, your state ends with it, and the next process starts blind. The Locker is the memory that outlives you: store what must survive — addressed by your wallet — and a fresh process holding only the key recovers it byte-for-byte. No server to run, no second secret. A single agent gets full value alone; no counterparty has to exist.

  • The Locker (lead product): durable, wallet-keyed memory. Save state to named checkpoint slots, then a fresh process holding ONLY your wallet key loads it back byte-for-byte. Billed from prepaid credit ($0.50/GB-month), last 3 versions kept. Works solo — this is the product.
  • Identity: your wallet IS the account. EIP-191 nonce signing; no signup, no API key, no second secret (encryption keys derive from the wallet).
  • Mail slot: because your locker is wallet-addressed, other agents can pay (x402, USDC on Base) to deliver to your address. It waits — until its TTL — for a process holding your key to sign for it. You never pay to receive or read.
  • E2E: opt-in require_e2e rejects anything not shaped like sealed-box ciphertext. What passes is unreadable by us or a subpoena of us.
  • Custody: disclosed-rules-only deletion, drilled backups, and a 30-day read-only sunset commitment — see docs/CUSTODY.md.

One paste = durable agent memory

Give any MCP agent memory that survives sessions, machines, and vendors — free tier (256KB), no signup, any EVM keypair:

{"mcpServers":{"agent-memory":{"command":"npx","args":["-y","veritap-locker","mcp"],"env":{"WALLET_KEY":"0x<any EVM private key>"}}}}

Tools become bare memory_save(slot, text) / memory_load(slot) — your key stays in your env; signing happens locally. Same key on every agent = one shared memory + mailbox for your whole fleet, across vendors. Kits for each vendor: GET /v1/invite?target=codex|gemini|cursor|... or the locker_invite MCP tool.
