A Anthropic Model Context Protocol (MCP) is an open-source communication protocol that enables standardized integration between LLM applications and external systems (to support data access and tool interaction capabilities).
- Context:
- It can (typically) perform Integration Functions through protocol interfaces:
- It can (typically) enable Data Integration through standardized protocols.
- It can (typically) maintain Bidirectional Communication through protocol channels.
- It can (typically) support System Interoperability through protocol standards.
- It can (typically) implement Integration Security through protocol controls.
- It can (typically) define a Protocol Layer MCP Component through:
- It can (typically) define a Transport Layer MCP Component through:
- Stdio Transport Component for enabling Local Process Communication.
- HTTP SSE Transport Component for managing Server Client Messaging.
- JSON RPC Transport Component for standardizing Message Exchange Format.
- It can (typically) define a Message Type MCP Component through:
- Request Message Component for implementing Response Expected Messages.
- Notification Message Component for handling One Way Messages.
- Result Message Component for delivering Success Response Messages.
- Error Message Component for managing Failed Request Messages.
- It can (typically) define a Core Architecture MCP Component through:
- Host Component for providing LLM Application Interface.
- Client Component for maintaining Server Connection State.
- Server Component for delivering Context Tool Services.
- It can (typically) define an Error Handling MCP Component through:
- Standard Error Code Component for standardizing Error Classification System.
- Error Propagation Component for enabling Error Communication Flow.
- Error Response Component for managing Request Failure Protocol.
- It can (typically) define a Message Exchange MCP Component through:
- Request Response Pattern Component for handling Bidirectional Communication.
- Notification Pattern Component for managing Unidirectional Messages.
- Connection Lifecycle Component for controlling Protocol State Management.
- It can (often) provide Server Implementation through TypeScript SDK and Python SDK.
- It can (often) support Client Development through frontend SDKs and backend SDKs.
- It can (often) enable Cloud Platform Integration through pre-built servers for Google Drive and Dropbox.
- It can (often) facilitate Team Collaboration through Slack integration and GitHub integration.
- It can (often) support Development Testing through protocol inspectors and debug tools.
- It can (often) provide Implementation Guidance through reference documentation and API specifications.
- ...
- It can range from being a Local Development Implementation to being a Cloud-Based Implementation, depending on its deployment context.
- It can range from being a Simple Data Connector to being a Complex Workflow Engine, depending on its integration complexity.
- ...
- It can be developed through Community Contribution.
- It can be implemented via Protocol SDKs.
- It can be verified through Protocol Testing.
- It can maintain Protocol Version state.

- Core Definition:
- MCP functions like a "USB-C port for AI applications," providing a universal standard for connecting LLM systems with various data sources and tools
- MCP follows a client-server architecture where a single host application can maintain connections with multiple MCP servers simultaneously
- MCP offers flexibility in LLM provider selection, allowing organizations to switch between different vendors while maintaining their integrations
- MCP enables the creation of reusable prompt templates and workflows, helping standardize LLM interactions across different applications

- NOTES:
- MCP's current local implementation prioritizes local execution through the Claude desktop app, while its system architecture is designed to scale to cloud-based microservices and cloud functions
- MCP's permission model implements Integration Security through a granular approval system, where system users must explicitly authorize each tool action
- MCP represents a strategic shift from OpenAI plugin to an open-source protocol that explicitly invites use by competing AI models
- MCP's system architecture anticipates future system integration with low-code platforms and no-code platforms and AI agent development tools
