A unified MCP (Model Context Protocol) server that provides advanced code manipulation and analysis capabilities for multiple programming languages
A unified MCP (Model Context Protocol) server that provides advanced code manipulation and analysis capabilities for multiple programming languages through Language Server Protocol integration. The typescript mcp mcp server wraps that behind the Model Context Protocol, so an assistant can use it through 14 defined tools rather than through you.
Everything the assistant can do here goes through one of these:
lsp_get_hover — Get type information and documentation for symbolslsp_find_references — Find all references to a symbol across the codebaselsp_get_definitions — Navigate to symbol definitions with optional code bodylsp_get_diagnostics — Check for errors and warnings in fileslsp_get_all_diagnostics — Get diagnostics for entire projectlsp_get_document_symbols — List all symbols in a filelsp_get_workspace_symbols — Search symbols across the entire workspacelsp_get_completion — Get code completion suggestionslsp_get_signature_help — Get parameter hints for function callslsp_format_document — Format entire documents using language serverlsp_rename_symbol — Rename symbols across the codebaselsp_get_code_actions — Get available quick fixes and refactoringsInstallation goes through your MCP client rather than a global install: point it at @mizchi/lsmcp on npm and it is fetched when the client starts. The copy-paste blocks for Claude Desktop, Claude Code and Cursor are further down this page.
Plenty of developer tooling servers cover similar ground. The differences that matter in practice are scope of access and how much setup stands between you and a working tool call. Typescript MCP's toolset — lsp_get_hover, lsp_find_references, lsp_get_definitions and 11 more — is a fair guide to whether it matches your workflow. It is maintained by mizchi; worth a glance at recent repository activity before you build anything load-bearing on it.
SyncDev reviews every entry in this directory against the project's own documentation before publishing, and revisits them as servers change.
