Using AI tools with Conversation API

You can use AI tools to facilitate the generation of code that you can use with Sinch's Conversation API.

In the sections below, we provide guidance on how LLMS, AI tools, and AI agents can consume and navigate our documentation using several different methods.

If you are using an AI tool, LLM, or agent to navigate our documentation site, you can visit our llms.txt page (located at https://developers.sinch.com/llms.txt) for a map of all the documentation files for Sinch.

This page is in plaintext, and it provides the title of each page, a description, and a link to the Markdown version of the page for easy LLM consumption and analysis.

Most pages on Sinch's developer documentation site has a Markdown counterpart.

The Markdown version of the page is in plaintext, making it easier for AI tools, LLMs, and agents to consume the contents.

To access the Markdown version of a page, simply append .md to the end of the URL. For example, to access the Markdown version of this page, simply add .md to the end of the URL in the address bar.

Additional examples are provided in the table below:

For a complete directory of Markdown pages, see our llms.txt page.

In order to generate code samples using AI tools, you may connect directly to Sinch's documentation MCP server. This will make several tools available to your system that facilitate endpoint identification, information lookups, and general context-setting.

The tools are described in the table below. Note that, while you may not have to explicitly call out these tools when designing your prompt (or using the prompts we provide later in this document), you must still ensure the tools are activated in whatever AI environment you work in:

You may connect to our documentation MCP server by clicking the Connect MCP button:

Alternatively, copy the following URL and add it to your AI tool: https://developers.sinch.com/mcp. Some examples of how to add the Sinch documentation MCP server tools to your AI solution are detailed in the tabs below:

    "sinch-mcp": {
      "url": "https://developers.sinch.com/mcp"
    }
  }
}

Skills files (or "skills") provide AI-specific guidance, hints, troubleshooting tips, and use-case information that can help your AI agents better understand various topics. They are especially helpful when using AI tools and agents in coding environments.

Sinch provides skills that help your AI solution navigate our documentation, generate code samples, and perform API calls.

To view Sinch's skills files, visit the Sinch Skills GitHub repo. The sub-sections below provide concise installation, usage, and structural information. For a more thorough explanation of Sinch Skills, see our dedicated developer document on Sinch Skills.

To make use of our skills files, you must install them in your coding environment. Information on ways to install Sinch's skills files are included on the tabs below:

Once Sinch's skills have been installed, your AI tool or agent should make use of them automatically. AI tools and agents will consult the skills files whenever you make a request.

Each skill lives in its own folder under skills/. The SKILL.md file contains YAML frontmatter (name and description) and markdown sections including Overview, Getting Started, Key Concepts, Common Patterns, Gotchas & Best Practices, and Links sections.

Sinch has developed several plugins and extensions for AI developer tools. These extensions and plugins help AI streamline code creation using Sinch's APIs.

The extensions, plugins, related artifacts, and installation instructions can be found in the corresponding IDE marketplaces, extension registries, and code repositories. The supported tools are linked below:

Tool	Description
Codex	Bundles the Sinch Build skills catalog with the hosted Sinch Docs MCP server. Codex can search authoritative Sinch developer documentation and follow product guides for Conversation API (SMS, RCS, WhatsApp), Voice, Verification, Numbers, Number Lookup, 10DLC, Elastic SIP Trunking, Fax, Mailgun, Provisioning, and Authentication. Documentation search requires no credentials. Optional bundled scripts can call live Sinch APIs, such as sending a test message or managing webhooks, using your own Sinch credentials and only with your approval; these calls may incur charges.
VS Code	This VS Code extension supports multiple Sinch and Mailgun products: Sinch Conversation API - One simple API to reach customers over multiple channels and deliver a mobile-first experience that's out of this world! Sinch Number Validation - Validate phone numbers in real-time to ensure deliverability and reduce costs. Mailgun Email Validation - Validate email addresses (single and bulk) to improve email deliverability and maintain sender reputation.
Open VSX	This Open VSX extension supports multiple Sinch and Mailgun products: Sinch Conversation API - One simple API to reach customers over multiple channels and deliver a mobile-first experience that's out of this world! Sinch Number Validation - Validate phone numbers in real-time to ensure deliverability and reduce costs. Mailgun Email Validation - Validate email addresses (single and bulk) to improve email deliverability and maintain sender reputation.
JetBrains	This JetBrains plugin supports the following Sinch products: Sinch Conversation API - One simple API to reach customers over multiple channels and deliver a mobile-first experience that's out of this world! Mailgun - Email validation and delivery service for verifying addresses and ensuring reliable email communication.
Cursor	This Cursor plugin contains skills for various Sinch products, commands to set up MCP, send messages, retrieve senders, list webhooks, create webhooks, update webhooks, delete webhooks, view webhook trigger lists, and view help information. An MCP JSON file is also provided here.
Kiro	A Kiro Power that connects the Sinch Build platform to your AI-assisted development workflow — send SMS, WhatsApp, and RCS messages, verify phone numbers, make voice calls, and manage virtual numbers without leaving your IDE. More information can be found at the Sinch Kiro Power repo.
Sinch Plugins	This repository contains Sinch plugins and related artifacts for AI developer tools. The repository supports: A Claude Code plugin that integrates the Sinch Conversation API, allowing you to send SMS messages, manage webhooks, and inspect your Sinch configuration directly from your terminal. This plugin includes the Sinch Build MCP (sinch) and the Sinch Docs MCP (sinch-docs). A Cursor IDE plugin that integrates the Sinch Conversation API, allowing you to send SMS and RCS messages, manage webhooks, and interact with your Sinch configuration directly from Cursor IDE. This plugin includes the Sinch Build MCP (sinch) and the Sinch Docs MCP (sinch-docs). A Gemini CLI extension that integrates the Sinch Conversation API, allowing you to send SMS messages, manage webhooks, and interact with your Sinch configuration directly from Gemini CLI. This extension includes the Sinch Build MCP (sinch) and the Sinch Docs MCP (sinch-docs via httpUrl). An Antigravity CLI plugin that integrates the Sinch Conversation API and related products. This is the native Antigravity successor to the Gemini CLI extension above; both remain available. A Codex plugin that bundles the Sinch Build skills catalog with the hosted, no-auth Sinch Docs MCP. It is read-only: Codex can search Sinch developer documentation and follow product guides.
