Create an audience segment from explicit subscription IDs, explicit emails, or custom-field rules; returns the segment and its initial calculation status.

Create Subscription

Create a new publication subscription without reactivating an unsubscribed address or sending a welcome email; supports attribution, initial custom fields, and newsletter-list assignment.

List Custom Fields

List the custom-field definitions available for subscriber metadata and dynamic audience segments in a publication, returning one page controlled by page and limit with pagination metadata for retrieving additional fields.

List Posts

Search a publication's posts by status, audience, channel, slug, tags, or author and optionally include content, recipients, or statistics.

List Publications

List publications accessible to the API key, optionally including publication statistics; use the returned publication IDs with publication-scoped tools.

List Segment Members

List full subscriber records currently included in an audience segment, optionally including stats, custom fields, referrals, tags, or premium tiers.

List Segments

List audience segments in a publication, filtered by segment type or calculation status, with optional latest statistics.

List Subscriptions

Search a publication's subscriptions by exact email or filter by status and tier, returning one cursor-controlled page of subscriber records.

Update Draft Post

Update content or presentation settings on an existing draft after verifying it is still a draft; refuses confirmed, archived, or sent posts and cannot publish or schedule.

Update Subscription Custom Fields

Set or remove custom-field values on one subscription without changing its email, tier, billing link, or subscribed status.

SETUP GUIDE

Connect Beehiiv MCP Tool with your Agent

1

Install Composio

typescript
npm install @composio/core ai @ai-sdk/mcp @ai-sdk/openai
Install the Composio SDK and your agent framework
2

Create a session with MCP enabled

typescript
import { Composio } from "@composio/core";

const composio = new Composio();
const { mcp } = await composio.create("your-user-id", {
  toolkits: ["beehiiv"],
  mcp: true,
});
Create a session scoped to Beehiiv and read its MCP URL and headers
3

Connect your agent to the MCP server

typescript
import { createMCPClient } from "@ai-sdk/mcp";
import { openai } from "@ai-sdk/openai";
import { generateText, stepCountIs } from "ai";

const client = await createMCPClient({
  transport: { type: "http", url: mcp.url, headers: mcp.headers },
});

const { text } = await generateText({
  model: openai("gpt-5.6-sol"),
  tools: await client.tools(),
  prompt: "Send newsletter to beta-subscribers segment",
  stopWhen: stepCountIs(10),
});

console.log(text);
await client.close();
Pass the session's MCP URL and headers to your agent and run a Beehiiv request

});

while (response.output.some((o) => o.type === "function_call")) {
  const outputs = await composio.provider.handleToolCalls(session, response.output);
  response = await client.responses.create({
    model: "gpt-5.6-sol",
    tools,
    previous_response_id: response.id,
    input: outputs,
  });
}

console.log(response.output_text);
Send a request, execute the Beehiiv tool calls through the session, and print the final answer

FAQ

Frequently asked questions

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

When you connect a Beehiiv account through Composio, every action runs under that account, so anything the agent creates, sends, or changes shows up in Beehiiv 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 Beehiiv. If Beehiiv 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 Beehiiv 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 Beehiiv 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 Beehiiv rejects the old key. Create a new key in Beehiiv and reconnect the account from the Composio dashboard or by asking your agent to reconnect Beehiiv. Nothing else changes.

Composio's free Hobby plan includes 100,000 tool calls per month with no credit card, which covers most personal Beehiiv use. Paid plans add higher limits and team features. Your Beehiiv 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 Beehiiv accounts).

With Composio, you connect Beehiiv 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.
