Overview

AI-generated overview

Non-custodial MCP server for tokenized stock tokens on Robinhood Chain 4663: registry lookups, prices, swap quotes and unsigned transaction plans.

What you can do
Look up canonical stock tokens, ETFs and core assets, and read metadata, Chainlink prices and wallet balances for them on chain 4663. Quote swaps across several venues, run pre-trade checks, and build unsigned swap plans the user signs. Manage agent sessions with scoped permissions, limits and a kill switch, plus session policy guardrails. Read Morpho Earn vault status and positions, and build unsigned deposit and withdraw plans. Check pricing, subscription tiers, fees, liquidity and system status, and build optional tip plans.
When to use it
Use it when an assistant needs to work with tokenized stocks on Robinhood Chain 4663: verifying official token addresses, reading prices and balances, comparing swap routes, or preparing transactions for a user to sign. It is not for US brokerage equities, which the server says belong to a separate trading server.
Requirements
A remote streamable HTTP endpoint at aatos.dev. An x-api-key header is optional for free tools and required for Pro tools such as quoting, simulation and plan building; the key is issued after an on-chain ETH payment. Access to Robinhood Chain 4663 and its price feeds.
Before you install
Pro and Team access is paid in ETH on-chain to a treasury, and swap plans include an ETH fee of about 10 bps; tips are optional. The server builds unsigned plans only and does not sign or broadcast, so the user signs and pays gas. Treat only registry addresses as real tokenized stocks, and stop when a quote or simulation reports it is not executable. Session and policy tools change agent permissions and limits.

Installation

In SourceWeft

  1. Open AI Agent Tokenized Stock OS in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/dev.aatos%2Faatos/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows
