## Introduction / Main Floor: agent-lsp: The LSP Code Intelligence Hub Built for AI Agents

An open-source tool that bridges the Language Server Protocol and Model Context Protocol, providing AI coding agents with over 50 code analysis tools, 20 predefined skill workflows, and 8 speculative execution capabilities, supporting CI validation integration for 30 programming languages.

## Background: Blind Spots of AI Coding Tools

Current mainstream AI coding assistants (such as Claude Code, Cursor, GitHub Copilot, etc.) have a fundamental flaw when generating code: they cannot see the complete code picture. When AI tries to modify a function, it doesn't know who calls this function, doesn't know what renaming would break, and can't confirm whether the build still passes after modification. This 'blind men touching an elephant' style of code editing leads AI to frequently produce incorrect modifications, forcing developers to spend a lot of time correcting them.

Language Servers could have provided these answers—they hold complete semantic information of the code, including definition jumps, reference lookups, type hierarchies, call relationships, etc. However, existing MCP (Model Context Protocol) and LSP bridging solutions have two fatal problems: either they cold start every request, leading to slow responses; or they directly expose the original tools to AI, which often can't use these tools correctly.

## Core Architecture of agent-lsp

agent-lsp is a stateful runtime based on real language servers. It builds a persistent code knowledge base through one-time workspace indexing, and on this basis adds a layer of skill encapsulation, encoding correct multi-step operations into reusable workflows.

## Bridge Between LSP and MCP

This project cleverly bridges two major protocols:

- **LSP (Language Server Protocol)**: The standard protocol for editors to obtain code intelligence, providing functions such as completion, diagnostics, definition jumps, etc.
- **MCP (Model Context Protocol)**: The standard way for AI tools to discover and call external tools

As an intermediate layer, agent-lsp exposes the intelligent capabilities of language servers to AI agents in the form of MCP tools, while ensuring the index remains in a hot state through stateful session management, enabling fast responses across files and projects.

## CI Validation Support for 30 Languages

Unlike other solutions that only list supported languages in configuration files, agent-lsp actually runs 30 real language servers for end-to-end validation in the continuous integration process. Every code push triggers automated tests for languages such as Go, Python, TypeScript, Rust, Java, C/C++, C#, Ruby, PHP, Kotlin, Swift, Scala, Zig, Lua, Elixir, Gleam, Clojure, Dart, Terraform, Nix, Prisma, SQL, MongoDB, etc. This "walk the talk" validation method ensures the reliability of language support.

## Speculative Execution: A Unique Innovation

agent-lsp's most innovative feature is speculative execution—simulating the impact of changes in memory before writing modifications to disk. This is a capability that no other MCP-LSP implementations have.

## Atomic Edit Simulation

The `simulate_edit_atomic` tool can preview the diagnostic impact of any edit, allowing users to see what will be broken before actually touching the files. This is particularly critical for assessing refactoring risks.

## Chain Change Evaluation

The `simulate_chain` tool goes a step further: it can evaluate a series of interdependent edits (such as renaming a function, updating all callers, modifying return types), and report which step first introduces an error. This allows complex refactoring to be fully validated before submission.
