erpnext-agent 0.30.0

ERPNext and Frappe REST/RPC MCP Server for Agentic AI!

Erpnext MCP

ERPNext and Frappe Framework enterprise resources planner. Built with the highest architectural standards, incorporating dynamic facades, custom API routing, and FastMCP tool decoration.

Documentation — Installation, deployment, usage across the MCP, API, and CLI interfaces, and guidance for provisioning the ERPNext / Frappe platform are maintained in the official documentation.

Overview

Erpnext MCP provides a high-performance, model-optimized interface to Erpnext capabilities. It isolates the model from underlying API transport complexity, ensuring safe, idempotent, and highly traceable system interactions.

---

Features

• Dynamic Facade Orchestration: Integrates multi-inheritance clients cleanly under a single facade.
• Battle-Tested Resilience: Out-of-the-box credential authentication, connection polling, and request retry strategies.
• FastMCP Declarative Tools: Fast, native schema registration with full inline validation.
• Complete Test Intent Diversity: Deep, automated unit, integration, and mock tests ensuring high code coverage.

⚙️ Dynamic Tool Selection & Visibility

This MCP server supports dynamic toolset selection and visibility filtering at runtime. This allows you to restrict the set of exposed tools in order to prevent blowing up the LLM's context window.

You can configure tool filtering via multiple input channels:

• CLI Arguments: Pass --tools or --toolsets (or their disabled counterparts --disabled-tools and --disabled-toolsets) during startup.
• Environment Variables: Define standard environment variables:
  • MCP_ENABLED_TOOLS / MCP_DISABLED_TOOLS
  • MCP_ENABLED_TAGS / MCP_DISABLED_TAGS
• HTTP SSE Request Headers: Pass custom headers during transport initialization:
  • x-mcp-enabled-tools / x-mcp-disabled-tools
  • x-mcp-enabled-tags / x-mcp-disabled-tags
• HTTP SSE Request Query Parameters: Append query parameters directly to your transport connection URL:
  • ?tools=tool1,tool2
  • ?tags=tag1

When query strings or parameters are supplied, an LLM-free Knowledge Graph resolution layer (using DynamicToolOrchestrator) matches query intents against known tool tags, names, or descriptions, with safe fallback and automated 24-hour background cache refreshing.

Installation

Install in editable mode directly inside your active workspace:

pip install -e .[all]

Or via the uv tool:

uv pip install -e .

---

Usage

You can launch the FastMCP server in stdio mode via Python module execution:

import asyncio
from erpnext_agent.mcp_server import get_mcp_instance

async def main():
    mcp = get_mcp_instance()
    # Execute stdio loop or launch server
    print("MCP Server ready.")

if __name__ == "__main__":
    asyncio.run(main())

For direct shell launch, execute:

python -m erpnext_agent.mcp_server

---

Configuration

The package is fully configurable via the environment variables listed below:

Variable	Description	Default	Required
ERPNEXT_URL	ERPNext / Frappe server endpoint URL	http://localhost:8000	Yes
ERPNEXT_TOKEN	API authentication token (api_key:api_secret)	your_api_key:your_api_secret	Yes

A local template is supplied inside .env.example. Copy this file as .env and fill out your specific service endpoint parameters before starting execution.

---

MCP Tools

The following declarative FastMCP tools are registered and available to upstream AI agents:

Tool Name	Description	Parameters
get_document	Get specific Frappe/ERPNext document by doctype and name	doctype: str, name: str
create_document	Create new Frappe/ERPNext document	doctype: str, data: dict
call_method	Call a whitelisted ERPNext RPC method	method: str, params: dict = None

See docs/overview.md or docs/concepts.md for deeper operational examples.

---

Architecture

This package uses the standardized Agent-Utilities dynamic facade architecture:

graph TD
    User([User Agent]) --> Server[FastMCP Server]
    Server --> Facade[Api Dynamic Facade]
    Facade --> ClientBase[ApiClientBase]
    Facade --> Auth[Credentials Auth Handler]
    ClientBase --> Service([External Service API])

---

Deployment

Bare-Metal (Standard pip)

1. Set up your Python virtual environment (>= 3.10).
2. Install the package: pip install .[all]
3. Export credentials:

   export ERPNEXT_URL="http://localhost:8000"
   

4. Run: python -m erpnext_agent.mcp_server

Container (Docker Compose)

A standard compose structure is provided inside the docker/ folder. Build and deploy:

docker compose -f docker/compose.yml up --build -d

---

Additional Deployment Options

erpnext-agent can also run as a local container (Docker / Podman / uv) or be consumed from a remote deployment. The Deployment guide has full, copy-paste mcp_config.json for all four transports — stdio, streamable-http, local container / uv, and remote URL:

• Local container / uv — launch the server from mcp_config.json via uvx, docker run, or podman run, or point at a local streamable-http container by url.
• Remote URL — connect to a server deployed behind Caddy at http://erpnext-mcp.arpa/mcp using the "url" key.
