VSCode tools and resources as a Model Context Protocol (MCP) server in a VSCode extension.
VSCode tools and resources as a Model Context Protocol (MCP) server in a VSCode extension. Exposed over MCP by the chpatil vscode mcp extension mcp server, that capability becomes something an assistant can invoke while it works, not something you go and do afterwards.
The VSCode MCP Server is a VSCode extension that acts as a Model Context Protocol (MCP) server integrated directly within VSCode. Its primary purpose is to expose a coding diagnostic tool—namely, the code_checker—which aggregates diagnostic messages (similar to those displayed in VSCode’s Problems panel) and makes them accessible to an external AI assistant via Server-Sent Events (SSE). This allows your assistant to invoke MCP methods and retrieve timely diagnostic information from your workspace.
mcp-proxy on PyPI is all you need. Most clients run it directly, so configuration is a few lines and a restart.
Everything the assistant can do here goes through one of these:
list_debug_sessions — Retrieve all active debug sessions in the workspacestart_debug_session — Start a new debug session with the provided configurationstop_debug_session — Stop debug sessions matching a specific session namerestart_debug_session — Restart a debug session by stopping it and then starting it with the provided configuration (new!)NOTE — This is different than just closing the window or using File > Close, which leaves the application running in the backgroundPrerequisites — 1. Clone the Repository: Clone the Semantic Workbench repository to your local machine:.vsix file in the project root.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. Chpatil Vscode MCP Extension's toolset — list_debug_sessions, start_debug_session, stop_debug_session and 3 more — is a fair guide to whether it matches your workflow. It is maintained by cspatil8; 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.
| Tool | What it does |
|---|---|
| list_debug_sessions | Retrieve all active debug sessions in the workspace. |
| start_debug_session | Start a new debug session with the provided configuration. |
| stop_debug_session | Stop debug sessions matching a specific session name. |
| restart_debug_session | Restart a debug session by stopping it and then starting it with the provided configuration (new!). |
| NOTE | This is different than just closing the window or using **File** > **Close**, which leaves the application running in the background. |
