With VS Code’s MCP resource support, which includes support for resource templates, resources returned from MCP tool calls become available to the model, can be saved in chat, and can be attached as context via the Add Context button in chat. Developers can browse resources across MCP servers, or for a specific server, by using the MCP: Browse Resources command, or using the MCP: List Servers command.
VS Code 1.101 offers experimental support for sampling, which allows MCP servers to make requests back to the model, and now supports MCP servers that require authentication, enabling interaction with an MCP server that operates on behalf of a user account for that service. Developers now can enable development mode to debug MCP servers by adding a dev key to the server config.
Finally, new MCP extension APIs enable extensions to publish collections of MCP servers. This means VS Code extension authors can bundle MCP servers with their extensions or build extensions that dynamically discover MCP servers from other sources.
