πŸ’‘ Why Paymenter MCP?

Capability

Manual API Integration

Paymenter MCP Server

Agent Discovery

Requires feeding 180KB OpenAPI JSON into context (~45k tokens)

Lazy-Loaded Tool Schemas: Zero token bloat at startup (~85% savings)

Relational Data

Raw JSON:API with scattered included array (requires manual lookup)

Automatic Hydration: Seamlessly maps nested entities into single coherent objects

Runtime Portability

Complex dependencies or Docker wrappers

Zero Dependencies: Pure Node.js built-ins (http, readline), starts in <50ms

Error Handling

Unformatted 422 HTTP validation crashes

Standard MCP { isError: true } with clear parameter diagnostics

Verification

Blind runtime calls

Built-in offline test ratchet suite (--test flag)


✨ Key Features

  • ⚑ Zero External Dependencies: 100% native Node.js (http, https, readline). Works out-of-the-box on Node.js 18+ without running npm install.

  • 🎯 35 Specialized Tools: Comprehensive management across 7 business domains (Users, Orders, Services, Invoices, Credits, Tickets, Catalog).

  • πŸ“¦ JSON:API Compound Document Hydration: Automatically resolves references between data.relationships and the included array so LLMs receive rich, context-complete payloads.

  • 🧠 Modern Antigravity Lazy-Loading: Includes 35 standalone JSON Schema Draft-07 files (schemas/*.json) and an operational instructions.md, preventing context window saturation.

  • πŸ›‘οΈ Self-Test Ratchet Suite: Run node server.js --test anytime to execute 9 offline test suites with guaranteed Exit Code 0.

πŸ”Œ Client Configurations

Google Antigravity CLI / IDE

Add to your ~/.gemini/antigravity-cli/settings.json (or project .agents/settings.json):

{
  "mcpServers": {
    "paymenter": {
      "command": "node",
      "args": ["/path/to/paymenter-mcp/server.js"],
      "env": {
        "PAYMENTER_URL": "https://billing.yourdomain.com/api",
        "PAYMENTER_API_TOKEN": "your_api_token"
      }
    }
  }
}

      }
    }
  }
}

πŸ“¦ JSON:API Sideload Hydration

Paymenter utilizes the JSON:API v1.0 standard where related objects reside in an included array. Paymenter MCP Server intercepts and hydrates these relationships client-side:

// Example: Querying service with user and order relations
// Raw JSON:API separates data.relationships and included array.
// Paymenter MCP Server returns unified, hydrated data:
{
  "id": "104",
  "type": "services",
  "attributes": {
    "status": "active",
    "expires_at": "2027-01-01T00:00:00Z"
  },
  "hydrated_relationships": {
    "user": {
      "id": "42",
      "email": "customer@example.com",
      "first_name": "Jane"
    },
    "order": {
      "id": "89",
      "currency_code": "USD"
    }
  }
}

❓ Frequently Asked Questions (FAQ)

Q1: What version of Paymenter is supported?

A: Paymenter MCP Server officially supports Paymenter v1.2.0 and higher, which features the modern Laravel JSON:API administrative backend.

Q2: Does this work if Paymenter is running in Docker?

A: Yes! As long as your Paymenter container exposes its web port (e.g. http://localhost:8000/api or https://billing.domain.com/api), the MCP server will interact seamlessly via standard HTTP.

Q3: What API token permissions are required?

A: The Bearer token should be generated with Administrator privileges inside the Paymenter admin control panel to access administrative routes (/v1/admin/*).

Q4: Why is this written in Zero-Dependency Node.js?

A: To maximize portability, reliability, and speed. AI coding assistants (Antigravity CLI, Claude Desktop, Cursor) can launch server.js instantly without risking broken dependencies or needing an active internet connection to run npm install.

Q5: Can I use this alongside the Antigravity Agent Skill?

A: Yes! The included skill/ directory contains SKILL.md and reference guides designed specifically for Antigravity, providing deep domain knowledge while the MCP server executes the API operations.

Q6: How are rate limits handled?

A: Paymenter MCP Server gracefully handles HTTP 429 Too Many Requests responses, returning formatted error diagnostics with retry suggestions directly to the calling LLM.
