FIWARE MCP Server

This is a first implementation of a FIWARE Model Context Protocol (MCP) Server that provides a bridge between the Context Broker and other services. The server implements basic operations for interacting with a FIWARE Context Broker.

Objectives

Create a basic MCP server implementation for FIWARE
Provide simple tools for Context Broker interaction
Demonstrate basic intent CRUD operations with the Context Broker
Serve as a foundation for more complex MCP implementations

Features

Context Broker version checking
Query capabilities for the Context Broker
Entity publishing and updating

Prerequisites

Python 3.7 or higher
pip (Python package installer)
Access to a FIWARE Context Broker instance

Installation

Clone this repository:

git clone <repository-url>
cd FIWARE_MCP_01

Install the required dependencies:

pip install -r requirements.txt

Claude Desktop integration

mcp install server.py

# Custom name
mcp install server.py --name "FIWARE MCP Server"

# Environment variables, if any
mcp install server.py -v API_KEY=abc123 -v DB_URL=postgres://...
mcp install server.py -f .env

Usage

Start the MCP server:

python server.py
# or
mcp run server.py

The server will start on 127.0.0.1:5001 by default.

Available Tools

CB_version
- Checks the version of the Context Broker
- Default parameters: address="localhost", port=1026
- Returns: JSON string with version information
query_CB
- Queries the Context Broker
- Parameters:
  - address (default: "localhost")
  - port (default: 1026)
  - query (default: "")
- Returns: JSON string with query results
publish_to_CB

Example Usage

# Example entity data
entity_data = {
    "id": "urn:ngsi-ld:TemperatureSensor:001",
    "type": "TemperatureSensor",
    "temperature": {
        "type": "Property",
        "value": 25.5
    },
    "@context": "https://uri.etsi.org/ngsi-ld/v1/ngsi-ld-core-context.jsonld"
}

# Publish to Context Broker
result = publish_to_CB(entity_data=entity_data)

Configuration

The server can be configured by modifying the following parameters in server.py:

Host address
Port number
Timeout settings
