Building

Delphi IDE

1. Open DelphiLSPMCPServer.dpr
2. Select Project → Build

Command Line

dcc64 DelphiLSPMCPServer.dpr

---

Usage

Command Line Options

DelphiLSPMCPServer [options]

Options:
  --lsp-path       Path to LSP executable
  --workspace      Workspace root or file:// URI
  --log-level     debug, info, warning, error
  --debug                Enable verbose diagnostics
  --wait                 Wait for debugger before startup
  --help                 Show help

---

Dynamic Workspace Discovery

Starting with v0.05, the server can automatically determine the active workspace.

Detection Strategy

1. MCP initialize request

   • Reads rootUri or rootPath

2. Current Working Directory fallback

3. Automatic .dpr / .lpr project detection

This allows AI agents to switch projects dynamically without restarting the server configuration.

---

AI Optimization

The repository includes:

• DelphiLSP.md

This file instructs AI agents to prioritize semantic tools such as:

• hover
• goto_definition

instead of relying on text-based searches.

Recommended GEMINI.md Setup

# Project Context

Refer to DelphiLSP.md for semantic code analysis instructions.
Use LSP semantic tools instead of grep/text searching whenever possible.
