What sets it apart
04
One config. Every AI surface.
Deploy on Abstraxn once. ChatGPT, Claude, Cursor, Windsurf, and Hermes all call the same MCP endpoint — same agent, same wallets, zero per-platform rebuilds.
Users stay where they already are.
No new app to install. Your Web3 agent surfaces inside the products people open every day. Adoption is instant because the UI is already familiar.
x402 pay-per-call, built in.
Agents discover paid APIs and settle in stablecoins per call — no manual key rotation. discover_services, get_service, paid_fetch — all wired and policy-bound from day one.
Non-custodial. Tenant-scoped. Always.
Transfers return unsigned transactions — your user signs, not Abstraxn. Every MCP session resolves to exactly one agent, one wallet context. No cross-tenant bleed.

One Abstraxn agent. Every surface your users already open.

03Flow
Up in three steps
  1. 01

    Roll out your agent — once.

    One API call: name, wallets, spend policy. You get an agent ID, an MCP endpoint, and a key. That's the entire setup.

  2. 02

    Point any MCP host at it.

    Paste your endpoint and key into ChatGPT's connector, Claude Desktop, or mcp.json for Cursor and Windsurf. One config per host — not per feature, not per chain.

  3. 03

    Users ask. The agent acts.

    "What's my Base balance?" The host model picks the right tool, calls it, returns the answer. No new app. No Web3 UX. Just the chat product they already open every day.

04Capabilities
Every MCP host gets the same surface

ChatGPT, Claude, or Cursor — the host auto-discovers an identical, model-documented tool surface. Predictable orchestration across every AI product, automatically.

Wallet & assets

Read addresses and native balances across EVM and Solana. Prepare unsigned transactions — the user always signs, Abstraxn never holds keys.

Discovery & payments

Find x402-monetized APIs by intent, resolve specific services by ID, and call paid endpoints with automatic per-call stablecoin settlement.

Chain & market data

Query live block state, on-chain data, and token prices across any supported network — on demand, inside any conversation.

05Integrate
Drop it in, done

One JSON stanza connects any MCP-capable host. Same config for Cursor, Claude Desktop, Hermes Agent, and ChatGPT — swap the host, keep the endpoint.

mcp.json

  "mcpServers": {
    "web3-agent-kit": {
      "url": "https://agent-kit.abstraxn.com/mcp",

      "headers": {
        "Authorization": "AGENT_API_KEY_FROM_CREATE_AGENT"
      }
    }
  }
}
  • REST first: create agent, bind wallets, set spend policy.
  • MCP endpoint: POST /mcp — same URL, any host.
  • Per-agent key for single-user assistants. App key + agent_id for multi-tenant platforms.
