And MCP makes the experience even better. With Castingwords MCP integration, you can draft, triage, summarise emails, and much more, all without leaving the terminal or the app, whichever you prefer. ## 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 Code](https://composio.dev/toolkits/castingwords/framework/claude-code) - [Claude Cowork](https://composio.dev/toolkits/castingwords/framework/claude-cowork) - [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 ### Why use Composio? Apart from a managed and hosted MCP server, you will get: - CodeAct: A dedicated workbench that allows GPT to write its code to handle complex tool chaining. Reduces to-and-fro with LLMs for frequent tool calling. - Large tool responses: Handle them to minimise 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 GPTs aren't overwhelmed by tools you don't need. ## Connect Castingwords to Codex ### How to install Castingwords MCP in Codex ### Run the setup command Run this command in your terminal to add the Composio MCP server to Codex. ```bash codex mcp add composio --url https://connect.composio.dev/mcp ``` ## 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 provides comprehensive access to Castingwords operations through Composio.

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 Codex? Yes, you can. Codex 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)
