TOOLS

Supported Tools

Every Voiceflow action and event your agent gets out of the box.

Create Variable

Create one user-defined variable in a Voiceflow project environment and return its assigned ID and configuration.

Delete Variable

Permanently delete one user-defined variable by ID.

Export Environment

Return a complete JSON snapshot of one Voiceflow environment, including agent, workflows, tools, functions, variables, and knowledge-base records.

Get Agent Configuration

Return one project environment's agent configuration; optionally include its large global prompt and instructions.

Get Conversation State

Read a user's Voiceflow conversation variables, storage, and execution stack for a draft or published environment.

Get Transcript

Return one transcript with its full conversation logs, properties, evaluations, and recording URL.

Import Knowledge Document from URL

Crawl one public web URL into a Voiceflow knowledge base and return the created document and ingestion status.

List Agent Components

List playbooks, API tools, functions, project-level evaluations, MCP servers or tools, attached tools, or tests for a Voiceflow project and, where applicable, an environment.

List Environments

Return a project's environments, aliases, release history, and live traffic percentages.

List Knowledge Documents

Return all knowledge-base documents in one project environment with their IDs, sources, ingestion status, and chunking settings.

List Projects

Return every Voiceflow project in one workspace, including project IDs used by agent, runtime, and authoring tools.

List Variables

Return system and user-defined variables in one project environment with IDs, defaults, descriptions, and ownership flags.

List Workspaces

Return every Voiceflow workspace accessible to the connected account, including IDs needed to list projects.

Publish Environment

Publish a Voiceflow environment as a named release.

Query Knowledge Base

Retrieve relevant document chunks and optionally synthesize an answer from a project's draft or published Voiceflow knowledge base.

Query Project Analytics

Return one Voiceflow project-level analytics metric as a time series for a requested date range and interval.

Search Transcripts

Search a project's conversation transcripts by time, environment, version, session, and transcript-property filters, returning one bounded page.

Send Conversation Message

Send one text turn to a Voiceflow agent and return its typed response traces; this invokes the agent and may consume model usage.

Update Conversation Variables

Merge named variable values into one user's existing conversation state without replacing storage or the execution stack.

Update Variable

Update selected editable fields of one user-defined variable; omitted fields remain unchanged.

SETUP GUIDE

  transport: {
    type: 'http',
    url: session.mcp.url,
    headers: {
      'x-api-key': 'your-composio-api-key',
    },
  },
});

const tools = await client.tools();
const { text } = await generateText({
  model: openai('gpt-4o'),
  tools,
  messages: [{
    role: 'user',
    content: 'YOUR_SPECIFIC_PROMPT_HERE'
  }],
  maxSteps: 5,
});

console.log(`Agent: ${text}`);

Use the MCP server with your AI agent (Anthropic Claude or Mastra)

FAQ

Frequently asked questions

Yes, Voiceflow requires you to configure your own API key credentials. Once set up, Composio handles secure credential storage and API request handling for you.

Yes! Composio's Tool Router enables agents to use multiple toolkits. Learn more.

Yes. Composio is SOC 2 Type II compliant and is built to keep your Voiceflow connection and credentials secure. OAuth tokens and API keys are encrypted, and sensitive customer data is protected at rest and in transit.

Composio also undergoes independent security testing and continuously monitors its systems for security threats. You can review the latest reports and policies in the Composio Trust Center.

Composio maintains and updates all toolkit integrations automatically, so your agents always work with the latest API versions.

Create the key in your Voiceflow account settings, then paste it once on Composio's connection page. Composio stores it encrypted and uses it only for the Voiceflow actions your agent runs. Nobody else in your workspace can read it, and you can revoke it inside Voiceflow at any time.

When you connect a Voiceflow account through Composio, every action runs under that account, so anything the agent creates, sends, or changes shows up in Voiceflow as done by you. Keep an approval step in your prompt for actions with side effects, such as sending or deleting, and have the agent draft first.

Whatever the credentials you connect allow inside Voiceflow. If Voiceflow lets you scope a key to specific permissions, create a scoped one so the agent can only do what you intend. You can revoke the key inside Voiceflow at any time.

Yes. Composio supports multiple connected accounts for the same app, and that works in Claude, ChatGPT, or any other assistant you connect through Composio. Give each Voiceflow connection a name such as work or personal, and the assistant uses the one you mention in the request. Each account keeps its own credentials and nothing is merged.

The connection stops working the moment Voiceflow rejects the old key. Create a new key in Voiceflow and reconnect the account from the Composio dashboard or by asking your agent to reconnect Voiceflow. Nothing else changes.

Composio's free Hobby plan includes 100,000 tool calls per month with no credit card, which covers most personal Voiceflow use. Paid plans add higher limits and team features. Your Voiceflow plan and its API limits still apply as usual.

Built-in connectors usually give one AI access to a limited set of apps. Many people use Composio because it lets their AI connect to more apps than it normally supports, or connect to multiple accounts for the same app (e.g. connect Claude to multiple Voiceflow accounts).

With Composio, you connect Voiceflow once and then use it across different AI assistants without setting it up separately in each one. Connect your apps to Composio once, then connect Composio to whichever AI you use, whether that's Claude, ChatGPT, Hermes, or your own custom assistant.
