About
The Language Server Protocol (LSP) defines the protocol used between an editor or IDE and a language server that provides language features such as autocomplete, go to definition, find all references, and documentation on hover. Adding these features for a programming language takes significant effort, and traditionally the work had to be repeated for each development tool because every editor or IDE exposed different APIs for implementing the same capabilities. LSP standardizes how language servers and development tools communicate, allowing the language-specific intelligence to live in a reusable server that can connect to multiple development environments through a shared protocol. This means a single Language Server can be reused across many tools, while development tools can support multiple languages with less duplicated effort. The protocol enables inter-process communication between the development tool and the language server and defines the format of messages using JSON-RPC.

About
WebMCP is an open source JavaScript library that allows any website to integrate with the Model Context Protocol, enabling users to connect to and interact with webpages through an LLM or AI agent. Developers can add WebMCP to a site with a simple script, which initializes a small widget that handles the connection between the webpage and an MCP client. Once connected, websites can expose MCP features including tools, prompts, resources, and sampling. Tools let an LLM perform actions on the website through registered functions with defined inputs and outputs. Prompts provide reusable templates for common LLM interactions and can accept dynamic arguments. Resources expose webpage data and content that clients can read and use as context, including page content, individual elements, files, or other structured information. WebMCP also supports sampling, allowing the server to request LLM completions through the connected client while maintaining human oversight.
