Connect AcqPath to an MCP client

Remote Streamable HTTP at api.getacqpath.com/mcp. No seller API key is required for public capabilities and quote preparation.

Separate stock marketplace endpoint

SUPPORTED SECURE MODE: tested official TypeScript/Node x402 2.25.0 and Python x402 2.22.0 with the AcqPath SIWX adapter on /v1/rights/preflight; unchanged signer and random nonce, recommended when payer-signed request binding is required. SUPPORTED STOCK WIRE MODE: the same official stock clients without SIWX, custom nonce, signer or buyer hook on /v1/rights/preflight/x402, fresh only, 0.02 USDC. Stock binds one request atomically at first valid use; it does not sign the POST body in advance. Zero-config compatibility outside this fixed stock endpoint, stock SIWX-only hooks, Payments MCP and generic paid proxies are not supported by this integration.

Same signed authorization plus same normalized request recovers the existing stock result; changed input or another route is rejected after binding. A pre-use leaked stock authorization can be raced for another same-priced request. Keep signed HTTP requests private. Never create a replacement authorization after an uncertain payment.

Rights Gateway: select the paid operation

LIVE Base USDC pricing: Secure Preflight 0.02 fresh / 0.05 deep per prepared settled report; Ingestion Gate 0.04 + 0.02 per distinct URL fresh or 0.06 + 0.04 per URL deep (1–4 eligible public HTTPS URLs); Revalidation 0.03 fresh / 0.06 deep. Stock x402 stays fresh-only 0.02 and reviewed-only. No new subscription, prepaid, API-key billing or invoicing plan is active.

A Secure Preflight may offer a disclosed paid UNKNOWN or no-declaration diagnostic after meaningful public-source observation. An outage with no usable source observation, invalid URL or exhausted safety budget is not billable Preflight. Gateway pricing covers a bounded observation attempt after verified authorization. UNKNOWN never authorizes content use.

Current supported buyer integration

Fresh 0.02 USDC; deep 0.05 USDC on Base eip155:8453. Pin the exact recipient, USDC asset, fee and Ed25519 verification key. The adapter verifies offer, report, receipt and delivery binding. Private checkpoint files retain bearer authorizations and are not application-level encrypted; protect them with private ACLs and encrypted storage.

Cursor / generic mcpServers configuration

Use a client that supports remote Streamable HTTP. Keep quote results containing claim_token in a private application path, not a shared conversation.

{
  "mcpServers": {
    "acqpath": {
      "url": "https://api.getacqpath.com/mcp"
    }
  }
}

VS Code mcp.json

Add the remote server to a workspace MCP configuration after reviewing its tool permissions.

{
  "servers": {
    "acqpath": {
      "type": "http",
      "url": "https://api.getacqpath.com/mcp"
    }
  }
}

This registers the public endpoint. It does not authorize a wallet or implement paid HTTP redemption.

Tools and payment boundary

acqpath_capabilities: read current capability metadata. acqpath_rights_quote: prepare a report quote; may fetch metadata and consume quota; returns a sensitive claim.

The runtime also lists a disabled legacy provider-routing tool. Exclude acqpath_quote from the integration allowlist. The distribution metadata cannot change the core tools/list response.

Initialize and list tools to test the connection. Only call quote when the selected supported resource actually needs evidence.
