🚀 Operational Guide

Deploying Servers in This Repository

TypeScript-based servers are executable directly using npx:

To launch the Memory server, for instance: sh npx -y @modelcontextprotocol/server-memory

Python-based servers require a package manager like uvx (recommended) or pip:

To launch the Git server: sh

Using uvx

uvx mcp-server-git

Using pip

pip install mcp-server-git python -m mcp_server_git

Refer to uv installation guides and pip installation instructions.

Integrating with an MCP Client

Servers require configuration within an MCP-compatible client application. Below shows configuration for the Claude Desktop client, enabling the previously launched server:

{ "mcpServers": { "memory": { "command": "npx", "args": ["-y", "@modelcontextprotocol/server-memory"] } } }

Further examples demonstrating client configuration for various services:

{ "mcpServers": { "filesystem": { "command": "npx", "args": ["-y", "@modelcontextprotocol/server-filesystem", "/path/to/allowed/files"] }, "git": { "command": "uvx", "args": ["mcp-server-git", "--repository", "path/to/git/repo"] }, "github": { "command": "npx", "args": ["-y", "@modelcontextprotocol/server-github"], "env": { "GITHUB_PERSONAL_ACCESS_TOKEN": "" } }, "postgres": { "command": "npx", "args": ["-y", "@modelcontextprotocol/server-postgres", "postgresql://localhost/mydb"] } } }

💬 Community Channels

⭐ Acknowledgement

Your support through starring this repository and contributing new server implementations is greatly appreciated!

Maintained by Anthropic, with substantial contributions from the global open-source community. The Model Context Protocol is committed to open standards and welcomes all contributions.

== Contextual Background == Business administration tooling encompasses the applications, methodologies, and controls utilized by enterprises to navigate market shifts, maintain competitive advantage, and enhance operational efficiency. These systems span departmental needs—from strategic planning and process control to record-keeping and decision support.

The rapid evolution of technology has complicated the selection of optimal business software. The constant pressure to reduce overhead and increase revenue, coupled with the necessity of deeply understanding customer requirements, means managers must adopt a strategic, adaptive approach to tool selection rather than simply adopting the newest trend.

== Dominant Management Tools (2013 Survey Benchmark) == A Bain & Company survey highlighted widely adopted management tools globally, reflecting regional priorities and market health. Key tools frequently cited include:

  • Strategic Planning Frameworks
  • Customer Relationship Management (CRM)
  • Employee Feedback Mechanisms
  • Benchmarking Analysis
  • Balanced Scorecard Implementation
  • Core Competency Definition
  • Outsourcing Strategy
  • Change Management Programs
  • Supply Chain Optimization
  • Mission/Vision Statement Development
  • Market Segmentation Analysis
  • Total Quality Management (TQM)

== Business Software Evolution == Business software evolved from rudimentary Management Information Systems (MIS) into integrated Enterprise Resource Planning (ERP) suites, later incorporating Customer Relationship Management (CRM), and now largely resides in the cloud-based business management domain. Value creation is maximized not just by IT investment, but critically by the efficacy of the implementation process and the precise selection and tailoring of the chosen tools to organizational mandates.

== Focus on Small and Medium Enterprises (SMEs) == Tools targeting SMEs are crucial as they offer scalable mechanisms for efficiency gains and market responsiveness with constrained resources.
