Integration

CallHub integration

CallHub is a calling and texting platform for campaigns and nonprofits. Manage contacts, phonebooks, tags, custom fields and Do Not Call lists; create call center campaigns and SMS broadcasts; rename, start, pause, end and delete call center, SMS and voice broadcast campaigns; manage agents and teams; upload media; read rented and validated numbers and credit usage. Starting a campaign calls or texts real people and is billed by usage (call duration, messages); texting and calling rules (opt-in, opt-out, recording consent) are the sender's duty. Rate limits: 20 requests per second overall, 2 per second for reads and 1 per second for creates, with daily caps. Contact addresses, cities, states, zip codes and custom field values, webhook target URLs and uploaded media URLs are not returned. Left out: changing a contact (its update may clear the withheld fields), the agent console (agent tokens, live calls, SIP), exports and download links, number renting, credit sharing, webhook creation, peer-to-peer, relational and voice broadcast creation, and routes with undocumented responses. Authentication: the account API key sent as 'Authorization: Token <key>', on the account's regional API domain.

Connect CallHub How integrations work

Ask it in chat

Say what should happen.
The workflow builds itself.

When this happens, do that in CallHub.Built from the 64 CallHub tools below, on the connection you add once.

What you can do with CallHub

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.

Use CallHub from Claude Code, Cursor or Codex

Connect CallHub in LiveContext, create an API key in Settings, then add the LiveContext MCP server to your client. Its CallHub 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
