Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

sinch-api-webhooks-list scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 4d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

List Webhooks

List all webhooks configured for your Sinch Conversation app. Webhooks allow you to receive real-time notifications about message events and other activities.

IMPORTANT: Execute this command directly. Do NOT generate script files. Do NOT create Python/JavaScript files. Perform the API call immediately using the instructions below.

Input

  • --format / -f: Output format (json or table) - optional, defaults to table

Arguments: $ARGUMENTS

Instructions

Execute these steps directly - do not write code or scripts:

  1. Check if $ARGUMENTS is empty or only contains the command name:

    • If empty or no meaningful arguments provided, use default format (table)
    • If user specifies a format preference, use that
    • Proceed to step 1
  2. Parse and validate arguments from $ARGUMENTS or use defaults:

    • If --format is not provided, default to "table"
    • Validate that format is either "json" or "table"
    • Normalize format to lowercase
  3. Try to call mcp__sinch__sinch-mcp-configuration to get the current configuration.

  4. If MCP is NOT available, retrieve configuration from environment variables:

    • CONVERSATION_PROJECT_ID
    • CONVERSATION_REGION
    • CONVERSATION_APP_ID
    • CONVERSATION_KEY_ID
    • CONVERSATION_KEY_SECRET
    • If any are missing, report: "Sinch API is not configured. Please set the required environment variables."
  5. Use the Sinch Conversation API to list webhooks:

    • Endpoint: GET https://{region}.conversation.api.sinch.com/v1/projects/{projectId}/apps/{appId}/webhooks
    • Extract region, projectId, and appId from the configuration
    • Include authorization header with the access token
  6. Use OAuth2 authentication to generate access token from key ID and secret.

  7. Display the results based on the requested format:

    • Table format: Display a formatted table with columns: ID, Target URL, Triggers (comma-separated), Target Type
    • JSON format: Display the raw JSON response
  8. Handle errors gracefully:

    • If configuration is incomplete, report: "Sinch API is not configured. Please set the required environment variables."
    • If the API call fails, display the error message with relevant details (status code, error description)
    • If no webhooks are found, display: "No webhooks found for this app."

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
