SETUP GUIDE

Connect CaptureKit 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: ["capturekit"],
  mcp: true,
});
Create a session scoped to CaptureKit 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: "Capture a full-page screenshot of https://example.com and return the image URL",
  stopWhen: stepCountIs(10),
});

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

Connect CaptureKit API Tool with your Agent

1

Install Composio

typescript
npm install @composio/core @composio/openai openai
Install the Composio SDK, the OpenAI provider, and the OpenAI SDK
2

Create a Composio session

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

const composio = new Composio({ provider: new OpenAIResponsesProvider() });
const client = new OpenAI();

const session = await composio.create("your-user-id", { toolkits: ["capturekit"] });
const tools = await session.tools();
Initialize Composio with the OpenAI Responses provider and create a session scoped to CaptureKit
3

Run CaptureKit tools with your agent

typescript
let response = await client.responses.create({
  model: "gpt-5.6-sol",
  tools,
  input: [{ role: "user", content: "Capture a full-page screenshot of https://example.com and return the image URL" }],
});

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 CaptureKit tool calls through the session, and print the final answer

Why Use Composio?

AI Native CaptureKit Integration

  • Supports both CaptureKit MCP and direct API based integrations
  • Structured, LLM-friendly schemas for reliable screenshot, crawl, and extraction tasks
  • Rich coverage for capturing webpages, parsing content, and running AI website analysis

Managed Auth

  • Bring your CaptureKit API key once; Composio stores and routes it securely
  • Central place to manage, scope, and revoke CaptureKit access
  • Works with auth flows like auth_configs.create(), connected_accounts.link(), and mcp.create() when you need lower-level control

Agent Optimized Design

  • Tools are tuned so agents can choose the right CaptureKit action for screenshots, crawls, or extraction
  • Clear inputs and outputs make webpage analysis easier for language models to reason about
  • Comprehensive execution logs so you always know what ran, when, and on whose behalf

Enterprise Grade Security

  • Fine-grained RBAC so you control which agents and users can access CaptureKit
  • Scoped, least privilege access for CaptureKit webpage capture and analysis workflows
  • Full audit trail of agent actions to support review and compliance
