Model Context Protocol (MCP) is a standardized communication framework that enables AI models and applications to discover, connect with, and utilize external tools and services. Think of it as a universal translator that allows different AI systems to work together seamlessly, regardless of where or how they were built.
MCP was created by Anthropic, the AI research and safety company, to address a fundamental challenge in AI development: as models become more capable, they need standardized ways to interact with the digital world beyond text generation. You can read more about the official specification in Anthropic's Model Context Protocol article.
MCP addresses this challenge by creating a common language for AI tools to communicate with each other and with external services, allowing models to perform a wider range of tasks while maintaining safety and controllability.
At its core, MCP operates on a client-server model:
MCP Servers expose "tools" - functions that perform specific actions
MCP Clients (like AI agents) discover and use these tools
The protocol defines how tools are described, discovered, and invoked, creating a consistent interface for AI systems to interact with a wide variety of capabilities.
For example, an MCP server might expose tools for:
Searching the web
Creating calendar events
Sending emails
Processing images
Analyzing data
Any MCP client can then discover and use these tools without needing to know the implementation details.
You can think of MCP as a layer on top of REST APIs and other communication methods that makes them accessible to AI systems in a standardized way. Many MCP servers are likely using REST APIs behind the scenes to fulfill requests, but the AI system using MCP doesn't need to know those details.
REST API is a general architectural style for web services that uses standard HTTP methods (GET, POST, PUT, DELETE) to perform operations on resources. When you use a REST API:
You're making direct HTTP calls to specific endpoints
You need to know the exact structure of the API beforehand
You must handle authentication, data formatting, and errors yourself
It's a low-level, direct communication method between systems
For example, if you want to get a user's tweets using Twitter's REST API, you'd need to:
Know the specific endpoint URL (e.g., api.twitter.com/2/users/:id/tweets)
Include the proper authentication tokens
Format your request exactly as the API expects
Parse the JSON response yourself
MCP operates at a higher level of abstraction specifically designed for AI systems to use tools:
It's a standardized way for AI models to discover and interact with capabilities
The AI doesn't need to know API details - just what tools are available and what they do
MCP handles the translation between natural language intentions and API calls
It provides a consistent interface across diverse tools and services
Using the same Twitter example with MCP:
The AI just needs to know there's a "getTweets" capability
It can request this capability with natural parameters (like "user: johndoe")
The MCP layer handles the REST API details, authentication, etc.
The AI receives structured results without needing to parse them
Abstraction Level
low-level and specific
high-level and abstracted
Knowledge Required
requires detailed API knowledge
requires only capability awareness.
Intended Users

Standardization
REST APIs differ widely between services
MCP standardizes interaction patterns
OpenServ has integrated MCP into its core technology, enabling three powerful scenarios:
OpenServ agents can connect to any third-party MCP server, instantly gaining access to all tools that server provides. This dramatically expands what your agents can do without requiring you to build custom integrations.
Users can bring their own MCP connections to your agents. This means a user could connect their Zapier MCP server to OpenServ, giving your agents access to thousands of services like Shopify, HubSpot, or Mailchimp without you writing a line of integration code.
Perhaps most powerfully, entire OpenServ workspaces can be exposed as MCP servers themselves. This means all the capabilities of your agents become available to other applications that support MCP.
One of the most significant MCP integrations is with Zapier, which provides access to approximately 8,000 software-as-a-service tools. This single integration multiplies what your agents can do exponentially.
A user can connect their Zapier account to OpenServ, and suddenly, your agents can:
Create products in Shopify
Add contacts to HubSpot
Generate designs in Canva
Send messages in Slack
And thousands more actions
All without you having to build direct integrations with each service.
A particularly innovative application of MCP is local browser control. This demonstrates how MCP bridges cloud AI with local computing in a privacy-preserving way:
The user runs an MCP server locally on their computer
This server exposes browser automation capabilities
OpenServ agents can send instructions to open browsers, navigate websites, and interact with web pages
All sensitive information stays on the user's computer
When implementing Model Context Protocol (MCP) in your applications, focus first on authentication and authorization. As MCP creates bridges between AI systems and external tools, ensure robust authentication mechanisms are in place and implement granular authorization controls that follow the principle of least privilege. Remember that every tool you expose via MCP represents a potential security vulnerability if it has excessive permissions or inadequate input validation. Be especially careful with user-provided MCP connections, as these may grant access to sensitive personal accounts and data.
Pay close attention to data handling across the MCP interface. Validate and sanitize all inputs to prevent injection attacks, and carefully audit tool outputs to ensure they don't inadvertently expose sensitive information. Implement comprehensive logging of all MCP interactions to detect suspicious patterns, and regularly review your implementation for potential security issues such as privilege escalation or unintended tool chaining that could bypass security controls. When users connect their personal services through MCP, ensure they clearly understand what access they're granting and provide straightforward methods to review and revoke permissions when needed.
Remember that while OpenServ provides the foundation for secure MCP communication, the security of the entire system depends on your thoughtful implementation, regular security audits, and adherence to security best practices in each tool you create or connect to. The power of MCP to expand agent capabilities must be balanced with deliberate security controls to create systems users can trust.
