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-senders-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 8d 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 Senders (Numbers API)

Interactive code generator for the Sinch Numbers API. This command helps you generate code snippets for listing virtual phone numbers.

IMPORTANT: Execute this command directly. Do NOT create script files. Either show an interactive menu or directly query the Numbers API based on user needs.

Input

No arguments required - this is an interactive command

Arguments: $ARGUMENTS

Instructions

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

  1. Present an interactive menu with the following options:

    • List all numbers
    • Filter by region code
    • Filter by type (MOBILE, LOCAL, TOLL_FREE)
    • Filter by capability (SMS, VOICE)
    • View pagination options
  2. Try to call mcp__sinch__sinch-mcp-configuration to get the current configuration.

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

    • CONVERSATION_PROJECT_ID (or NUMBERS_PROJECT_ID)
    • CONVERSATION_KEY_ID (or NUMBERS_KEY_ID)
    • CONVERSATION_KEY_SECRET (or NUMBERS_KEY_SECRET)
    • If any are missing, report: "Sinch API is not configured. Please set the required environment variables."
  4. Based on user selection, generate TypeScript code examples showing:

    • How to authenticate with Sinch Numbers API
    • How to make the API request with proper filters
    • How to handle pagination
    • How to process the response
  5. Display the generated code with syntax highlighting if available.

  6. Optionally, if user requests it, execute the code directly:

    • Use the Sinch Numbers API
    • Endpoint: GET https://numbers.api.sinch.com/v1/projects/{projectId}/activeNumbers
    • Use OAuth2 authentication with key ID and secret
    • Apply any filters from user's menu selection
    • Display results in a formatted table
  7. Provide execution instructions and next steps.

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.
