Bruno MCP Studio

Turns an agent's API testing into files you keep: it authors and edits Bruno collections in place, then runs them - HTTP, WebSocket and gRPC, one identity or many - and reports per-request pass/fail you can re-run in CI. Its 20 documented tools cover environment, request, collection, script. It runs locally over stdio via the published package.

People connecting API integration tools to Claude, Cursor, VS Code, or another MCP client. The project is written in TypeScript.

01 · Install Bruno MCP Studio

before you install - you'll need

The README does not document required environment variables for a basic install.

Claude Code

claude mcp add ostico-bruno-mcp-studio -- npx -y @ostico/bruno-mcp

Claude Desktop / Cursor / VS Code - add to config

{
  "mcpServers": {
    "ostico-bruno-mcp-studio": {
      "command": "npx",
      "args": [
        "-y",
        "@ostico/bruno-mcp"
      ]
    }
  }
}

Same JSON for Cursor. For VS Code, rename the top-level key from `mcpServers` to `servers`.

Using another client? Same JSON, different key

03 · What Bruno MCP Studio can do

Prose above is summarized from the project's README and registry record - no invented capabilities.

What you can build

With this server connected, an agent can find collections from Bruno's workspace.yml, move or copy a request to another folder or collection, read one request back as JSON, same shape for .bru and .yml, and delete one or more request files. Needs confirm: true.

Collection

3 tools - e.g. New collection. format: "yaml" (default) or "bru". Also registers it in the workspace, so list_collections and the Bruno app can see it - registerInWorkspace: f; Counts by method, folders, environments…
