Integration

eTermin integration

eTermin is an online appointment booking system (German, GDPR hosted in Frankfurt). Find free time slots, create, list, update and delete appointments, read deleted appointments, manage CRM contacts and vouchers, set calendar absences and weekly or date-specific working times, and read calendars, services, service groups, sent message logs, customer ratings and survey results. Creating and changing calendars, services and service groups, anchor times, return times, number-search user mappings, the sync-system appointment routes, booking page logs, contact permission and frequency settings, and the contact update route (whose identifier the vendor does not document; use create_contact with updatewhenexistsgdt=1 to upsert) are not exposed. Authentication sends three headers on every call: publickey (your API key), salt and signature. eTermin's docs ask for a random salt per request; this connection sends one fixed salt with its signature, which you compute once as base64(HMAC-SHA256(salt, secret key)) as in eTermin's code samples.

Say what should happen.
The workflow builds itself.

When this happens, do that in eTermin.Built from the 33 eTermin tools below, on the connection you add once.

What you can do with eTermin

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 eTermin from Claude Code, Cursor or Codex

Connect eTermin in LiveContext, create an API key in Settings, then add the LiveContext MCP server to your client. Its eTermin 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": {
