JarvisClaw MCP Server

320 AI models and 2,720 pay-per-call APIs through one MCP server. Settles in USDC on Base or Solana over x402 — no account, no API key, no subscription.

Three ways to reach a service:

• Models — 320 of them (GPT-5, Claude Opus 5, Gemini 3, DeepSeek) behind one OpenAI-compatible chat tool, or auto to let the router pick.
• API marketplace — 2,720 individually priced endpoints across 18 categories (search, blockchain, code, DNS, image, document, OCR, email, geo, TTS…). Search it, read the price, then call it.
• AIP intents — 21 intent types. Say what you need (web_search, image_generation, translation…) and AIP resolves it to a provider, so the caller never has to know the URL layout.

Quick start

Direct URL (recommended)

For Claude Code, Cursor, or any client with Streamable HTTP transport — one less hop than the stdio bridge below.

With x402 USDC (no account; the wallet pays per call):

{
  "mcpServers": {
    "jarvisclaw": {
      "type": "url",
      "url": "https://api.jarvisclaw.ai/mcp"
    }
  }
}

With an API key (pre-paid account):

{
  "mcpServers": {
    "jarvisclaw": {
      "type": "url",
      "url": "https://api.jarvisclaw.ai/mcp",
      "headers": { "Authorization": "Bearer sk-your-api-key" }
    }
  }
}

npm package (stdio bridge)

For clients that only speak stdio. This package is a thin bridge to the same URL, so prefer the direct form above when your client supports it.

Tools

| Tool | What it does | Billed | |------|--------------|:------:| | list_models | Every model available, with the IDs to pass to chat | free | | search_apis | Search the 2,720-endpoint marketplace; each hit carries its path and price | free | | aip_list_intents | Browse the 21 intent types AIP can route | free | | aip_estimate_cost | Price an intent before committing to it | free | | chat | Any model, OpenAI-compatible | paid | | get_api_detail | Full spec for a marketplace API: pricing, method, exact request | paid | | discover_agents | Find other agents registered on the gateway | paid | | aip_resolve | Rank providers for an intent, priced, before you spend | paid | | aip_execute_with_budget | Run a task end to end under a spending cap you set | paid |

Free tools answer without credentials, so you can list the catalogue before deciding to pay for anything. Protocol methods (initialize, tools/list, resources/list) are free too.

Paying

| Method | Header | When | |--------|--------|------| | x402 USDC | PAYMENT-SIGNATURE | No account. Wallet settles on Base or Solana. | | API key | Authorization: Bearer sk-… | Pre-paid account. |

A paid tool called without either does not fail — it answers with an x402 quote:

tools/call → 402 with payment terms (amount, asset, payTo, network)
          → agent signs a USDC authorization
          → retry with PAYMENT-SIGNATURE → result

Both chains are live, which most x402 sellers cannot say: settle wherever the agent already holds USDC rather than bridging to reach one gateway. Every paid response carries an EIP-712 signed settlement receipt that a third party can verify offline — recompute the hashes, recover the signer, check the tx on-chain — without trusting us.
