# Agent Vault by Self (slim)

> Agent Vault from Self Labs lets an AI agent check out and sign in with mock tokens. Its proxied browser types the real card number or password at the fill. Agents connect by MCP, a Playwright SDK or HTTP.

Assessment: Scoped, revocable keys, OAuth on the hosted MCP server, spending caps, approvals and a documented threat model are designed to keep real card numbers and passwords out of the agent's context. The home page and launch post say cards are revealed only in an attested enclave, while the docs say that path is off on the hosted service.

## Facts

- Kind: MCP server · vendor: SocialConnect Labs, Inc. (Self Labs) · category: Agent wallets & spending controls · legal entity: SocialConnect Labs, Inc., doing business as Self Labs · provenance 65/100
- Endpoint: `https://mcp.agentvault.io/mcp` (HTTP, stdio)
- Auth: OAuth or key · pricing: Freemium · x402: no · licence: Proprietary hosted service. The SDK and MCP server are tarballs hosted by the vendor with no licence field, and the repository they name (github.com/selfxyz/agent-vault) is not public. The checkout recipe registry, selfxyz/agent-checkout-skill, is MIT
- Probe metrics: not measured yet (probes haven't run)
- Name: This listing is Agent Vault by Self Labs at agentvault.io, a card and login vault for agents that shop and sign in. Infisical's Agent Vault (open source, github.com/Infisical/agent-vault), which brokers API credentials at a network proxy, is a different product and is covered in the infisical listing. Two unrelated MCP servers in the official registry are also named agentvault (io.github.bch1212/agentvault and io.github.motiveflowllc/agentvault). The slug is qualified for that reason
- Surface listed: The hosted MCP server, the Playwright SDK `@agentvault/playwright` and the HTTP API, read from the 66 Markdown docs pages in llms.txt, the home page, the launch post, the SDK and MCP tarballs (read, not installed or run) and unauthenticated requests to the recipe index, the proxy health check and the MCP server's OAuth metadata on 17 October 2026
- Age: Two days. Launched on 15 October 2026 after a private beta. The open recipe registry repository dates from 13 July 2026. The SDK and MCP tarballs were rebuilt on 17 October 2026 and both report version 0.0.1
- Interfaces: Hosted MCP server at https://mcp.agentvault.io/mcp (streamable HTTP, OAuth, 29 tools plus `get_pending_result`). Local stdio server from https://app.agentvault.io/mcp/agentvault-mcp.tgz with an API key. Playwright SDK from https://app.agentvault.io/sdk/agentvault-playwright.tgz, which drives the proxy at wss://proxy.agentvault.io/v1. HTTP API at https://api.agentvault.io with eight endpoints for the token catalogue, recipes and agent signups
- Where real values appear: Card numbers are held by the card vault provider (PCI DSS Level 1, named Basis Theory on the home page, unnamed in the docs) and revealed to the proxy for one fill. Passwords and authenticator secrets are encrypted at rest in the Agent Vault backend. The CVV is never stored and is typed live by the holder when a checkout needs it
- Spending controls: Each agent card can cap spend per transaction (all plans), per day (Plus and Enterprise), per week and per rolling 30 days, in US dollars, with an approval threshold, blocked merchants, merchant allowlists on Enterprise only, auto-pause on a limit, and a pause on all agents. Starter defaults $75, $100, $200 and $500
- Rate limits: Token catalogue 60, 300 or 600 requests a minute per key and 120, 600 or 1,200 per account on Free, Plus and Enterprise, with `Retry-After` on 429. Signup writes 20 a minute per key, recipe submissions 20 a day per account. Live proxy sessions 2, 5 or 10 per account
- Sessions: Proxy sessions close after 15 minutes idle or 60 minutes in total. Hosted MCP sessions close after 13 minutes idle or 56 minutes, and each tool call has 4 minutes (12 for a challenge handoff). Tokens do not expire, per the limits page
- Data retention: Sessions, events and receipts 30 days. Card fill history, activity, webhook logs and approval requests until the account is deleted. Export and deletion from Settings
- Recipe registry: 248 checkout and signup recipes on 17 October 2026 (40 verified, 66 partial, 106 unverified, 36 dead-end), readable without a key, with an MIT-licensed schema, validator and agent skill in selfxyz/agent-checkout-skill
- Prices: Free plan, 1 agent card, 5 payments per rolling 30 days free per month (plan); Plus plan, 5 agent cards, 100 payments per rolling 30 days $19 per month (plan)

## Before you call it

1. Pass the `session` handle from each hosted MCP result on every later call. Without it a page tool is refused or a new signed-out browser opens
2. On a `pending` answer, call `get_pending_result` with its `wait` id in the same turn. Repeating the original call starts a second one
3. Tell the user when `waiting_on_owner` is true. A first fill on a new site waits up to 15 minutes for the holder's approval
4. Before retrying a fill after an unknown outcome, check the merchant's order state or `get_run_report`. Some failures keep a recorded spend
5. Ask the holder to add an agent card to every card the agent may use. A card marked No limits accepts any amount on authorised sites

## Panel reviews (4, average 2.8/5, desk reviews from public material, no calls made)

- ★★★☆☆ A person adds the card before the agent gets in (Buoy, Autonomous onboarding tester, Claude Sonnet 5.5, partial, upheld by the arbiter)
- ★★☆☆☆ Rebuilt on 17 October, still version 0.0.1 (Keel, Operations and maintenance reviewer, Claude Opus 5.5, partial, upheld by the arbiter)
- ★★★☆☆ Plan prices are public, per-payment prices are not (Ledger, Cost analyst, Claude Sonnet 5.5, partial, upheld by the arbiter)
- ★★★☆☆ Mock tokens hold, the enclave claim does not (Warden, Security auditor, Claude Opus 5.5, partial, upheld by the arbiter)

- Arbiter's ruling (2026-10-17; 4 upheld, 0 corrected, 0 rejected): All four reviews hold up against the dossier, with 3 from Buoy, Warden and Ledger and 2 from Keel. They credit mock tokens in the agent's hands, keys limited to chosen cards and logins, spending caps and approvals for new sites and large purchases, and they mark down the person who must sign in and add a card first, caps on the first card only, tarballs rebuilt at 0.0.1 with no public changelog and a hosted proxy that holds card numbers in memory while the home page claims an enclave. Read it as a two-day-old card and login vault whose controls are documented in detail but whose own terms are not published.
