Compatibility & limits
An honest look at where Xvantage MCP stands across different AI tools, including what we've seen work best from real‑world testing. We update this page as we add and test more clients.
Looking for pricing?
Every AI client has its own pricing model and it changes often — we don't publish prices here to avoid giving you stale info. Refer to each platform's product site for current rates. We've linked them from the Quick start cards.
AI client support
| Client | Status | Notes |
|---|---|---|
| Claude Desktop | Fully supported | Our most tested path. Strongest tool‑call reliability and handles partial names without exact matches. |
| Claude.ai web | Fully supported | Via built‑in integrations UI. Easiest onboarding. |
| ChatGPT Custom GPTs | Fully supported | Strong conversational quality. Good for sharing a pre‑built GPT. |
| OpenAI Platform | Fully supported | Assistants API and Agents SDK. Excellent accuracy for dev builds. |
| Cursor | Fully supported | Developer IDE workflows with native MCP support. |
| Windsurf | Fully supported | Cascade agent mode. Similar experience to Cursor. |
| GitHub Copilot | Partial | Requires VS Code 1.99+, Copilot Business or Enterprise, and MCP policy enabled by an admin. |
| Microsoft Copilot Studio | Partial | Works across Trial, M365 Copilot, and Standalone licenses. Enterprise setup takes longer. |
| Google Gemini Agent Builder | Inconsistent | Capable but needs extensive system‑prompt tuning. Better for teams already deep in GCP. |
| Other MCP‑compatible tools | Should work | Any client that supports remote MCP servers. |
Which models perform best?
We see the strongest results with Claude Sonnet and GPT‑4 class models. Smaller or older models may struggle to pick the right tool or interpret results.
