Click on "Deploy Server".
Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state.
In the chat, type
@followed by the MCP server name and your instructions, e.g., "@lsp-mcp-rsget hover info for line 42 in app.js"
That's it! The server will respond to your query, and you can continue using it as needed.
Here is a step-by-step guide with screenshots.
lsp-mcp-rs
MCP server that bridges to any LSP. One binary, multiple language servers.
Build
cargo build --releaseBinary: target/release/lsp-mcp-rs.exe
Related MCP server: VSCode LSP MCP Server
Configure
Create config.toml next to the binary:
[servers.lua]
command = "C:/path/to/lua-language-server.exe"
args = ["--stdio"]
extensions = [".lua"]
[servers.rust]
command = "rust-analyzer"
args = []
extensions = [".rs"]
[servers.python]
command = "pyright-langserver"
args = ["--stdio"]
extensions = [".py"]Add to Claude Desktop config (claude_desktop_config.json):
{
"mcpServers": {
"lsp": {
"command": "X:\\path\\to\\lsp-mcp-rs.exe",
"args": []
}
}

All position arguments are 0-indexed.
How it works
MCP request comes in with a file path
File extension maps to configured LSP server
LSP spawns on first use, stays running
Request forwarded to LSP, response returned via MCP

The Remote MCP server acts as a standardized bridge between LLM applications (like Claude, ChatGPT, and Cursor) and external services, enabling AI agents to access external tools and resources. Its primary capability is providing a centralized search tool to discover other MCP servers and their respective tools. Unlike local implementations, it runs remotely with OAuth authentication and permission controls for security.
