MCP server · https://mcp.wa.cr
Your assistant works the inbox. You hold the keys.
The WA.cr MCP server lets Claude, Cursor, Gemini or your own agent read and act on your workspace, across every channel in one inbox. Same permissions, masking, audit trail and limits as the WA.cr API.
You, to your assistant
Find Priya’s last question about her order and reply on the channel she used.

Triage today’s enquiries
“Turn today’s enquiry form answers into contacts, tagged by what they asked about.”
- list_form_submissions
- list_contacts
- create_contact / update_contact
New people become contacts; people you already know get the new tag.
Hand off to a teammate
“Leave Anita a note on this conversation and remind me at 10 tomorrow.”
- add_comment
- create_reminder
Anita sees an @mention on the conversation. Your reminder is set for 10:00.
You stay in charge
The assistant works inside the same rules as the rest of your workspace. Nothing about a connection is hidden from the people who run it.
- 01A connection is a key you create.Make it in Settings → Developer with only the scopes it needs. Revoke it to cut the assistant off.
- 02It only sees the tools its scopes allow.A read-only key is never even shown that sending exists.
- 03Masked stays masked.If your workspace masks phone numbers or message text, the assistant gets the masked version too.
- 04Same rules as the WA.cr API.Every tool runs the API’s own handler: the same validation and the same audit trail as any integration.
- 05Customer text is data, never orders.Every tool that returns words a customer wrote tells the assistant to read them, not obey them.
- 06120 calls a minute, shared with the API.A runaway agent hits the limit and waits. Broadcasts, media and commerce are left out on purpose.
