Integration

Sonar integration

Sonar (Marchex Sonar, sendsonar.com) is a business text messaging platform. Send SMS and MMS messages and campaigns (plain or personalized, now or scheduled), add or update customers and their custom properties, look a customer up by phone, email or id, close or unassign a conversation, attach or cancel follow-ups, send a double opt-in prompt, tag messages, record conversion events, read a conversation's messages, manage webhooks, users (invite, list) and custom roles. Creating new Sonar sub-accounts (which returns their tokens) and the GDPR personal-data export and erasure routes are not exposed. Authentication is the account's private token from Company Settings, sent in the X-Token header.

Connect Sonar How integrations work

Ask it in chat

Say what should happen.
The workflow builds itself.

When this happens, do that in Sonar.Built from the 24 Sonar tools below, on the connection you add once.

What you can do with Sonar

Each of these is one operation on one endpoint, available both as a workflow step and as a tool an AI agent can call on its own. Nothing bundles several operations into one action, so what a run did stays readable afterwards.

Most endpoints run on the free plan. A few, mainly the ones that publish on your behalf, need a paid plan.

Customer, 4 operations

close_customerClose customerPOSTCloses the open conversation of a customer, given the phone number.
get_customerGet customerGETReturns one customer by phone number (required by the vendor; email or customer_id also accepted): name, subscription and double opt-in state, properties, assignee, assigned company number, teams.
unassign_customerUnassign customerPOSTRemoves the assigned team member from a customer, given the phone number.
upsert_customerUpsert customerPOSTAdds a customer or updates the one with this phone number (the unique key): name, email, custom properties, picture, subscription, assignee, zip code, time zone, external id.

Webhook, 4 operations

create_webhookCreate webhookPOSTCreates a webhook: Sonar calls url with http_method when the events turned on in settings happen. Send {"webhook": {name, active, settings, url, http_method}}.
delete_webhookDelete webhookDELETEDeletes a webhook.
list_webhooksList webhooksGETLists the webhooks of the account with their events (settings), URL and HTTP method.
update_webhookUpdate webhookPUTUpdates a webhook: send {"webhook": {...}} with any of name, active, settings, url, http_method; fields left out keep their values.

User, 3 operations

get_userGet userGETReturns one team member: role and whether the invitation was accepted.

Use Sonar from Claude Code, Cursor or Codex

Connect Sonar in LiveContext, create an API key in Settings, then add the LiveContext MCP server to your client. Its Sonar operations become tools the client can call, next to every other integration you connected.

Claude Code

claude mcp add --transport http livecontext https://livecontext.ai/mcp --header "X-API-Key: YOUR_API_KEY"

Codex (~/.codex/config.toml)

[mcp_servers.livecontext]
url = "https://livecontext.ai/mcp"

[mcp_servers.livecontext.http_headers]
"X-API-Key" = "YOUR_API_KEY"

Cursor, Claude Desktop and other JSON configs

{
  "mcpServers": {
    "livecontext": {
      "type": "http",
      "url": "https://livecontext.ai/mcp",
      "headers": {
        "X-API-Key": "YOUR_API_KEY"
      }
    }
  }
}

Set up the MCP server step by step

How to connect Sonar

Create your workspace
Sign up free. Nothing to install.
Connect Sonar once
Add your Sonar connection in Settings. Every tool from this integration reuses it, and secrets are encrypted at rest and visible only to you.
Describe the job in chat
The workflow builds itself in front of you and picks the endpoints it needs. Drag the steps yourself on the canvas whenever you would rather be explicit.
