Connector
Claude
22 tools, 20 of them offered on the default scopes. Add by URL.
Steps
Open Settings, then Connectors
In Claude, go to Settings and find Connectors. This is the same place your other connectors live.
Add a custom connector
Choose to add a custom connector and paste https://cresva.ai/mcp into the URL field. There is nothing else to fill in: Claude reads the rest from the URL.
Sign in and choose what Claude may read
Cresva's consent screen opens. It lists exactly what you are granting. The two read permissions are on by default and the one write permission is not, so a connection that never asks for it can never reach it.
Ask something in the next conversation
Try "which of my campaigns is pacing over budget". Claude picks the tool itself.
https://cresva.ai/mcpCresva cannot start this for you
