Code MCP MCP server exists for a simple reason — assistants are far more useful when they can act on Code MCP directly instead of describing what you should do. This monorepo contains the VSCode MCP Server and its companion VSCode Extension, which together enable AI agents and assistants, like Goose or Claude, to interact with VSCode through the Model Context Protocol.
Once Code MCP is connected, these are the calls the assistant has available:
create_diff — The create_diff tool exposed by this serveropen_file — The open_file tool exposed by this serveropen_project — The open_project tool exposed by this servercheck_extension_status — The check_extension_status tool exposed by this serverget_extension_port — The get_extension_port tool exposed by this serverlist_available_projects — The list_available_projects tool exposed by this servervscode-mcp-server on npm is all you need. Most clients run it directly, so configuration is a few lines and a restart.
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. Code MCP's toolset — create_diff, open_file, open_project and 3 more — is a fair guide to whether it matches your workflow. It is maintained by block; worth a glance at recent repository activity before you build anything load-bearing on it.
We check each listing at SyncDev against the project's documentation before it goes live — if something here drifts out of date, it is a bug worth reporting.
