You can do this in two different ways: - Via [Composio Connect](https://dashboard.composio.dev/login?utm_source=toolkits&utm_medium=framework_template&utm_campaign=claude-code&utm_content=composio_connect&next=%2F~%2Forg%2Fconnect%2Fclients%2Fclaude-code) - Direct and easiest approach - Via [Composio SDK](https://docs.composio.dev/docs?utm_source=toolkits&utm_medium=framework_template&utm_campaign=claude-code&utm_content=composio_sdk) - Programmatic approach with more control ## Also integrate Castingwords with - [OpenAI Agents SDK](https://composio.dev/toolkits/castingwords/framework/open-ai-agents-sdk) - [Claude Agent SDK](https://composio.dev/toolkits/castingwords/framework/claude-agents-sdk) - [Claude Cowork](https://composio.dev/toolkits/castingwords/framework/claude-cowork) - [Codex](https://composio.dev/toolkits/castingwords/framework/codex) - [OpenClaw](https://composio.dev/toolkits/castingwords/framework/openclaw) - [Hermes](https://composio.dev/toolkits/castingwords/framework/hermes-agent) - [CLI](https://composio.dev/toolkits/castingwords/framework/cli) - [Google ADK](https://composio.dev/toolkits/castingwords/framework/google-adk) - [LangChain](https://composio.dev/toolkits/castingwords/framework/langchain) - [Vercel AI SDK](https://composio.dev/toolkits/castingwords/framework/ai-sdk) - [Mastra AI](https://composio.dev/toolkits/castingwords/framework/mastra-ai) - [LlamaIndex](https://composio.dev/toolkits/castingwords/framework/llama-index) - [CrewAI](https://composio.dev/toolkits/castingwords/framework/crew-ai) ## TL;DR - Only one MCP URL to connect multiple apps with Claude Code with zero auth hassles. - Programmatic tool calling allows LLMs to write its code in a remote workbench to handle complex tool chaining. Reduces to-and-fro with LLMs for frequent tool calling. - Handling Large tool responses out of LLM context to minimize context rot. - Dynamic just-in-time access to 20,000 tools across 1000+ other Apps for cross-app workflows. It loads the tools you need, so LLMs aren't overwhelmed by tools you don't need. ## Connect Castingwords to Claude Code ### Connecting Castingwords to Claude Code using Composio 1. Add the Composio MCP to Claude ```bash claude mcp add --scope user --transport http composio https://connect.composio.dev/mcp ``` ## What is Claude Code? Claude Code is Anthropic's command line developer tool that lets you use Claude directly inside your terminal. Instead of switching between your editor, browser, and chat, you can stay in your project folder and ask Claude to help you build, debug, refactor, and understand code right where you're working. Key features include: - Terminal-Native Experience: Work with Claude directly in your command line without switching contexts - MCP Support: Built-in support for Model Context Protocol servers to extend Claude's capabilities - Project Context: Claude understands your project structure and can read, write, and modify files - Interactive Development: Ask questions, debug code, and get help in real-time while coding - Multi-Platform: Works on macOS, Linux, WSL, and Windows ## What is the Castingwords MCP server, and what's possible with it? The Castingwords MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Castingwords account. It provides structured and secure access to transcription services, so your agent can place new orders, check account balances, manage webhooks, and upgrade or refund audio files on your behalf. - Seamless transcription ordering: Let your agent initiate new audio or video transcription jobs using just a media URL—no manual uploads needed. - Account balance and SKU checks: Effortlessly retrieve your prepay balance or list available transcription services and pricing before placing orders. - Webhook management and testing: Register, verify, and test webhooks to automatically receive transcript completion notifications in your own systems. - Transcription order management: Upgrade completed jobs (for example, to add timestamps), or cancel and refund audio files before work begins if needed. ## Supported Tools | Tool slug | Name | Description | |---|---|---| | `CASTINGWORDS_CANCEL_AUDIOFILE` | Cancel and Refund Audio File | Tool to cancel an ordered audio file and issue a refund if applicable. Use when no transcription work has been done on the file (Pre-Processing, Audio Processing, Error states). | | `CASTINGWORDS_GET_PREPAY_BALANCE` | Get Prepay Balance | Tool to retrieve the current prepay balance for the account. Use when you need to check available funds before placing new transcription orders. | | `CASTINGWORDS_GET_TRANSCRIPT` | Get Transcript | Tool to retrieve the transcript for a given audiofile in the requested format (txt, doc, rtf, or html). Use after a transcription order has been completed. | | `CASTINGWORDS_GET_WEBHOOK` | Get registered webhook URL | Tool to retrieve the currently registered webhook URL for account notifications. Use when you need to verify your webhook setup. | | `CASTINGWORDS_ORDER_TRANSCRIPT` | Order Transcript | Create a transcription order for audio/video files at publicly accessible URLs. Returns order ID and audiofile IDs for tracking. Requires prepaid balance for non-test orders. Use test=true to validate URLs without charges. | | `CASTINGWORDS_ORDER_UPGRADES` | Order Upgrades | Tool to order an upgrade for a specific audio file. Use after transcription is complete to add items like timestamps or extra editing. Example: 'Order timestamps for file 12345'. | | `CASTINGWORDS_REGISTER_WEBHOOK` | Register Webhook | Registers a webhook URL to receive CastingWords event notifications. When events occur (e.g., transcript completion, refund issued, difficult audio), CastingWords will POST to your registered URL with event details. Use CASTINGWORDS_GET_WEBHOOK to verify the current webhook, and CASTINGWORDS_TEST_WEBHOOK to test notifications. | | `CASTINGWORDS_SKU_LIST` | List Available SKUs | Retrieves all available CastingWords transcription service SKUs with pricing. Use this tool to discover available services (transcription, captions, etc.) and their per-minute prices before placing an order. Returns SKU codes needed for order placement. | | `CASTINGWORDS_TEST_WEBHOOK` | Test Webhook Call | Tool to request a test webhook call for a specific event type. Use after registering a webhook URL to ensure webhook notifications are functioning properly. | ## Supported Triggers None listed. ## Creating MCP Server - Stand-alone vs Composio SDK The Castingwords MCP server is an implementation of the Model Context Protocol that connects Claude Code (and other AI assistants like Claude and Cursor) directly to your Castingwords account. It provides structured and secure access so Claude can perform Castingwords operations on your behalf. With Composio's managed implementation, you don't have to create your own developer app. For production, if you're building an end product, we recommend using your own credentials. The managed server helps you prototype fast and go from 0-1 faster. ## Step-by-step Guide ### 1. Prerequisites Before starting, make sure you have: - Claude Pro, Max, or API billing enabled Anthropic account - Composio API Key - A Castingwords account - Basic knowledge of Python or TypeScript ### 1. Install Claude Code To install Claude Code, use one of the following methods based on your operating system: ```bash # macOS, Linux, WSL curl -fsSL https://claude.ai/install.sh | bash # Windows PowerShell irm https://claude.ai/install.ps1 | iex # Windows CMD curl -fsSL https://claude.ai/install.cmd -o install.cmd && install.cmd && del install.cmd ``` ### 2. Set up Claude Code Open a terminal, go to your project folder, and start Claude Code: - Claude Code will open in your terminal - Follow the prompts to sign in with your Anthropic account - Complete the authentication flow - Once authenticated, you can start using Claude Code ```bash cd your-project-folder claude ``` ### 3. Set up environment variables Create a .env file in your project root with the following variables: - COMPOSIO_API_KEY authenticates with Composio (get it from [Composio dashboard](https://dashboard.composio.dev/login?utm_source=toolkits&utm_medium=framework_template&utm_campaign=claude-code&utm_content=api_key&next=%2F~%2Forg%2Fconnect%2Fclients%2Fclaude-code)) - USER_ID identifies the user for session management (use any unique identifier) ```bash COMPOSIO_API_KEY=your_composio_api_key_here USER_ID=your_user_id_here ``` ### 4. Install Composio library No description provided. ```python pip install composio-core python-dotenv ``` ```typescript npm install @composio/core dotenv ``` ### 5. Generate Composio MCP URL No description provided. ```python import os from composio import Composio from dotenv import load_dotenv load_dotenv() COMPOSIO_API_KEY = os.getenv("COMPOSIO_API_KEY") USER_ID = os.getenv("USER_ID") composio_client = Composio(api_key=COMPOSIO_API_KEY) composio_session = composio_client.create( user_id=USER_ID, toolkits=["castingwords"], ) COMPOSIO_MCP_URL = composio_session.mcp.url print(f"MCP URL: {COMPOSIO_MCP_URL}") print(f"\nUse this command to add to Claude Code:") print(f'claude mcp add --transport http castingwords-composio "{COMPOSIO_MCP_URL}" --headers "X-API-Key:{COMPOSIO_API_KEY}"') ``` ```typescript import 'dotenv/config'; import { Composio } from '@composio/core'; const { COMPOSIO_API_KEY, USER_ID } = process.env; if (!COMPOSIO_API_KEY || !USER_ID) { throw new Error('COMPOSIO_API_KEY and USER_ID required in .env'); } const composioClient = new Composio({ apiKey: COMPOSIO_API_KEY }); const composioSession = await composioClient.create(USER_ID, { toolkits: ['castingwords'], }); const composioMcpUrl = composioSession?.mcp.url; console.log(`MCP URL: ${composioMcpUrl}`); console.log(`\nUse this command to add to Claude Code:`); console.log(`claude mcp add --transport http castingwords-composio "${composioMcpUrl}" --headers "X-API-Key:${COMPOSIO_API_KEY}"`); ``` ### 6. Run the script and copy the MCP URL No description provided. ```python python generate_mcp_url.py ``` ```typescript node --loader ts-node/esm generate_mcp_url.ts # or if using tsx tsx generate_mcp_url.ts ``` ### 7. Add Castingwords MCP to Claude Code In your terminal, add the MCP server using the command from the previous step. The command format is: - claude mcp add registers a new MCP server with Claude Code - --transport http specifies that this is an HTTP-based MCP server - The server name (castingwords-composio) is how you'll reference it - The URL points to your Composio Tool Router session - --headers includes your Composio API key for authentication After running the command, close the current Claude Code session and start a new one for the changes to take effect. ```bash claude mcp add --transport http castingwords-composio "YOUR_MCP_URL_HERE" --headers "X-API-Key:YOUR_COMPOSIO_API_KEY" # Then restart Claude Code exit claude ``` ### 8. Verify the installation Check that your Castingwords MCP server is properly configured. - This command lists all MCP servers registered with Claude Code - You should see your castingwords-composio entry in the list - This confirms that Claude Code can now access Castingwords tools If everything is wired up, you should see your castingwords-composio entry listed: ```bash claude mcp list ``` ### 9. Authenticate Castingwords The first time you try to use Castingwords tools, you'll be prompted to authenticate. - Claude Code will detect that you need to authenticate with Castingwords - It will show you an authentication link - Open the link in your browser (or copy/paste it) - Complete the Castingwords authorization flow - Return to the terminal and start using Castingwords through Claude Code Once authenticated, you can ask Claude Code to perform Castingwords operations in natural language. For example: - "Transcribe this podcast episode from its URL" - "Check my available transcription balance now" - "Order timestamps upgrade for file 12345" ## Complete Code ```python import os from composio import Composio from dotenv import load_dotenv load_dotenv() COMPOSIO_API_KEY = os.getenv("COMPOSIO_API_KEY") USER_ID = os.getenv("USER_ID") composio_client = Composio(api_key=COMPOSIO_API_KEY) composio_session = composio_client.create( user_id=USER_ID, toolkits=["castingwords"], ) COMPOSIO_MCP_URL = composio_session.mcp.url print(f"MCP URL: {COMPOSIO_MCP_URL}") print(f"\nUse this command to add to Claude Code:") print(f'claude mcp add --transport http castingwords-composio "{COMPOSIO_MCP_URL}" --headers "X-API-Key:{COMPOSIO_API_KEY}"') ``` ```typescript import 'dotenv/config'; import { Composio } from '@composio/core'; const { COMPOSIO_API_KEY, USER_ID } = process.env; if (!COMPOSIO_API_KEY || !USER_ID) { throw new Error('COMPOSIO_API_KEY and USER_ID required in .env'); } const composioClient = new Composio({ apiKey: COMPOSIO_API_KEY }); const composioSession = await composioClient.create(USER_ID, { toolkits: ['castingwords'], }); const composioMcpUrl = composioSession?.mcp.url; console.log(`MCP URL: ${composioMcpUrl}`); console.log(`\nUse this command to add to Claude Code:`); console.log(`claude mcp add --transport http castingwords-composio "${composioMcpUrl}" --headers "X-API-Key:${COMPOSIO_API_KEY}"`); ``` ## Conclusion You've successfully integrated Castingwords with Claude Code using Composio's MCP server.

With a standalone Castingwords MCP server, the agents and LLMs can only access a fixed set of Castingwords tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from Castingwords and many other apps based on the task at hand, all through a single MCP endpoint. ### Can I use Tool Router MCP with Claude Code? Yes, you can. Claude Code fully supports MCP integration. You get structured tool calling, message history handling, and model orchestration while Tool Router takes care of discovering and serving the right Castingwords tools. ### Can I manage the permissions and scopes for Castingwords while using Tool Router? Yes, absolutely. You can configure which Castingwords scopes and actions are allowed when connecting your account to Composio. You can also bring your own OAuth credentials or API configuration so you keep full control over what the agent can do. ### How safe is my data with Composio Tool Router? All sensitive data such as tokens, keys, and configuration is fully encrypted at rest and in transit. Composio is SOC 2 Type 2 compliant and follows strict security practices so your Castingwords data and credentials are handled as safely as possible. --- [See all toolkits](https://composio.dev/toolkits) · [Composio docs](https://docs.composio.dev/llms.txt)
