A stable endpoint for clients that snapshot tool definitions
Some agent platforms, Salesforce Agentforce among them, save a copy of every tool definition when you register an MCP server. When we improve a tool description on our side, the platform marks the server out of sync and blocks your agent until you register it again, and registering again can clear your agent's configuration.
For those platforms, connect to https://gateway.ansvar.eu/stable/mcp. It runs on the same servers as https://gateway.ansvar.eu/mcp, with the same sign-in, credentials, plans and tool behaviour. The difference is the tool list. On the stable endpoint, tool names, descriptions and input schemas are frozen. We change them only in a deliberate refresh, announced to you before it happens. A tool we add after a freeze does not appear on the stable endpoint until the next refresh.
The stable endpoint checks each call against the frozen schema, the one your platform saved. Plan limits and the usual argument checks still apply. If your client reloads the tool list on its own, keep using /mcp: it gets every improvement the day we ship it.
