Tools & Capabilities Breakdown
Fiftyone MCP Server Tools (3)
SDK
Data operations that work everywhere (datasets, aggregations, schema, samples, operators, plugins). No App connection needed.
APP
Controls the FiftyOne App UI in real time (set_view, open_panel, notify, select_samples, reload, and 25+ more). Requires a connected browser via `ctx.ops`.
SESSION
Bootstrap tools for starting a local App server (launch_app). Used from terminal environments.
Growthbook MCP Tools (3)
growthbook_call_api
Make an authenticated HTTP request to the GrowthBook REST API on the user's behalf. Use method + path (+ optional JSON body) exactly as shown in skill workflows that mention gb-call. Paths typically start with /api/v1/ or /api/v2/. Returns the raw response body on success. IMPORTANT: Before POST, PUT, PATCH, or DELETE, confirm with the user (summarize method, path, and body) unless they have already explicitly instructed you to perform that mutation. GET requests do not need confirmation.
Ready-to-Paste Client Configurations
Paste either (or both) of these JSON server blocks into your client config file (e.g. claude_desktop_config.json or ~/.cursor/mcp.json).
