LspSAFE

An Model Context Protocol (MCP) server that provides LLMs/AI Agents with the capabilities of a language server protocol (LSP) server. This gives the AI the ability to get language aware context from the codebase.

Example

Input:

Use lsp to give me insights into the following typescript code:

let foo = "bar";
function x() {
let foo = 123;
console.log(foo);
}
x();
console.log(foo);

Output:

I'll use LSP (Language Server Protocol) to analyze your TypeScript code. Let me break down what's happening:
Here's what the code does and the insights from LSP analysis:

1. Variable Shadowing:

There are two variables named foo:

A global foo (string type) initialized with the value "bar"
A local foo (number type) inside the function x() initialized with the value 123

2. Execution Flow:

First, the global foo is declared and assigned the value "bar"
When function x() is called, the local foo variable is declared and assigned 123
The console.log(foo) inside the function outputs 123 (the local variable)
After the function finishes, console.log(foo) outputs "bar" (the global variable)

3. Scope Isolation:

The LSP confirms that TypeScript correctly identifies the different types:

The global foo is a string type
The local foo inside the function is a number type

Changes to the local foo don't affect the global foo

This is a classic ex
