General Liquidity MCP Server

MCP server for the General Liquidity machine economy API. Enables AI agents to resolve, pay, verify, and disclose — autonomous payment operations over the machine economy.

What It Does

General Liquidity is a machine-to-machine payment protocol. This MCP server wraps their OpenAPI 3.1 spec into agent-callable tools:

  • Resolve — Look up accounts, counterparties, and payment rails
  • Pay — Execute payments between machine-economy participants
  • Verify — Confirm transaction settlement and reconciliation
  • Disclose — Share verifiable credentials and transaction proofs

Business Operator Use Cases

Use Case Value
Autonomous Treasury Agent-managed payments between corporate entities with verification
Machine Payments IoT/automated system payments (energy trading, logistics settlement)
Cross-Border Settlement Machine-economy rails for cross-border B2B payments
Verifiable Disclosure Share payment proofs and credentials without exposing full transaction data

Installation

git clone https://github.com/general-liquidity/general-liquidity-mcp
cd general-liquidity-mcp
npm install

Configuration

{
  "mcpServers": {
    "general-liquidity": {
      "command": "node",

Tools Provided

  • resolve_account — Look up account details and capabilities
  • initiate_payment — Create a payment instruction
  • verify_settlement — Confirm transaction finality
  • disclose_credential — Share verifiable proofs
  • get_rails — List available payment rails and fees

Limitations

  • 0 stars, brand new — Created July 22, 2026. Barely documented.
  • Machine economy focus — Not a general-purpose payment API. Optimized for automated/machine payments.
  • API key required — General Liquidity access needed.
  • Unclear regulatory status — Machine-to-machine payments may have different regulatory treatment than consumer payments. Verify with legal counsel.

Operator Verdict

★★★ Forward-looking, not yet operational. The machine economy concept is real (IoT payments, autonomous settlement) but adoption is early. General Liquidity MCP is an infrastructure play — valuable if you're building in the machine economy space, but not yet a drop-in replacement for traditional payment processing.
