MCP
Model Context Protocol (MCP) is an open protocol standard proposed by Anthropic to standardize the way large language models (LLMs) interact with external tools, data sources, and services regarding contextual information. MCP defines how a model requests, receives, and utilizes external context, supporting capabilities such as tool invocation and resource access. It enables AI applications to integrate diverse external systems in a standardized manner, enhancing model extensibility and interoperability.
Core Facts
When connecting to multiple MCP servers simultaneously, tool descriptions alone can consume thousands or even tens of thousands of tokens.
MCP defines three core primitives: Tools (tool invocation), Resources (resource reading), and Prompts (prompt templates).
MCP aims to address the fragmentation problem in connecting large language models with external data sources and tools.

Exoproc is based on stdio transport: the client starts the server as a child process, and the two exchange JSON-RPC messages through standard input/output, with no need to open network ports.
Exoproc is a stdio-based open-source MCP server that lets Claude Code connect to active Windows x64 processes.
Interviewers may ask questions such as 'What is a vector database?', 'How does RAG mount a knowledge base?', and 'What is MCP?', which have become must-ask questions for large-model-oriented positions.
Both MCP and Skill were originally product standards proposed by Claude Code and were later widely cited, and LangChain quickly provided direct support for them in its Deep Agents module.
In complex agent projects, the toolchain includes retrieving data from the existing Java project via the MCP gateway protocol, calling a remote charting tool to generate visualizations, and using multiple crawler tools based on the Scrapy framework to scrape quotation information.
The uploader previewed that the next episode will explain how to connect local large models to MCP, forming a complete closed loop from model to hardware.
The MCP protocol itself does not provide security policies (such as least privilege, whitelists, and log auditing); the design of security boundaries is entirely the responsibility of the deployer.
Yisu's AI test automation platform has integrated simulation capabilities through CarMaker MCP.
The CarMaker AI Agent's MCP tools are divided into four categories by simulation stage: engineering information reading and query tools before simulation, vehicle configuration and test case modification tools in the preparation stage, simulation launch and status query tools in the execution stage, and result reading and metric calculation tools in the results stage.
In the CarMaker scenario, once simulation capabilities are encapsulated as standardized MCP tools, they not only serve the CarMaker AI Agent but can also be quickly integrated by other MCP-compatible agent platforms.
