## Quo Frequently Asked Questions

**What are the Quo Messages tools?**

This page lists the Messages tools in the Quo integration: 3 tools for working with messages. Each is exposed through your firm's Weave MCP connection and available to members whose access level permits it.

**Why did sending a text to a US number fail?**

Sending to US numbers requires the connected Quo account to have completed US Carrier Registration, a Quo-side prerequisite. Once registered, send-message works for US recipients.

**How do I read a specific conversation's messages?**

list-messages takes a Quo phone number plus the participant(s), a single number for a 1:1 thread, or the full participant set for a group conversation.

**What is the Quo integration?**

The Quo integration connects your firm's Quo account to Weave. Quo is a cloud phone/SMS platform. This integration exposes calls, messages, contacts, conversations, and tasks as governed MCP tools, scoped per member by access level. It groups 36 tools into 6 categories, exposed through your firm's Weave MCP connection and filtered per member by access level.

**How does my firm connect Quo to Weave?**

An admin connects Quo once for the whole firm by entering your Quo workspace API key in the Weave console. Every member then works through that single connection; there is no per-user Quo login. Your key is encrypted at rest and stays inside Weave's infrastructure.

**Do I need to install or configure anything locally?**

No. Weave is fully hosted, so there is nothing to install, run, or maintain on your own machines. After an admin connects Quo once from the console, each member simply points their AI assistant at your firm's Weave MCP endpoint, and the tools they are allowed to use appear automatically based on their access level.

**Can everyone on my team use every tool?**

No. Tools are exposed per member by access level, so each person only sees the Quo tools their role permits.

**Are changes made through these tools reversible?**

Reads are always safe. Sending a text cannot be undone, once sent it can't be recalled, and it spends the workspace's prepaid SMS credits. Deletes are irreversible: delete-contact and delete-task permanently remove the record from Quo. Most other actions can be reversed with a follow-up tool (for example reopen-task or unassign-task).

**Why can't I send a text to a US number?**

Sending SMS to US numbers requires your Quo account to have completed US Carrier Registration. That is a Quo-side prerequisite; once it is done, send-message works for US recipients.
