By the end, you'll have a working Bubble agent that can create a new user in your bubble app, update a record in the bubble database, fetch all orders from your bubble store through natural language commands. This guide will help you understand how to give your Mastra AI agent real control over a Bubble account through Composio's Bubble MCP server. Before we dive in, let's take a quick look at the key ideas and tools involved. ## Also integrate Bubble with - [OpenAI Agents SDK](https://composio.dev/toolkits/bubble/framework/open-ai-agents-sdk) - [Claude Agent SDK](https://composio.dev/toolkits/bubble/framework/claude-agents-sdk) - [Claude Code](https://composio.dev/toolkits/bubble/framework/claude-code) - [Claude Cowork](https://composio.dev/toolkits/bubble/framework/claude-cowork) - [Codex](https://composio.dev/toolkits/bubble/framework/codex) - [OpenClaw](https://composio.dev/toolkits/bubble/framework/openclaw) - [Hermes](https://composio.dev/toolkits/bubble/framework/hermes-agent) - [CLI](https://composio.dev/toolkits/bubble/framework/cli) - [Google ADK](https://composio.dev/toolkits/bubble/framework/google-adk) - [LangChain](https://composio.dev/toolkits/bubble/framework/langchain) - [Vercel AI SDK](https://composio.dev/toolkits/bubble/framework/ai-sdk) - [LlamaIndex](https://composio.dev/toolkits/bubble/framework/llama-index) - [CrewAI](https://composio.dev/toolkits/bubble/framework/crew-ai) ## TL;DR Here's what you'll learn: - Set up your environment so Mastra, OpenAI, and Composio work together - Create a Tool Router session in Composio that exposes Bubble tools - Connect Mastra's MCP client to the Composio generated MCP URL - Fetch Bubble tool definitions and attach them as a toolset - Build a Mastra agent that can reason, call tools, and return structured results - Run an interactive CLI where you can chat with your Bubble agent ## What is Mastra AI? Mastra AI is a TypeScript framework for building AI agents with tool support. It provides a clean API for creating agents that can use external services through MCP. Key features include: - MCP Client: Built-in support for Model Context Protocol servers - Toolsets: Organize tools into logical groups - Step Callbacks: Monitor and debug agent execution - OpenAI Integration: Works with OpenAI models via @ai-sdk/openai ## What is the Bubble MCP server, and what's possible with it? The Bubble MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Bubble applications. It provides structured and secure access to your Bubble backend, so your agent can perform actions like creating and updating database entries, running workflows, fetching app data, and managing users on your behalf. - Automated database management: Your agent can create, update, or delete entries in your Bubble app’s database, streamlining data operations without manual input. - Workflow execution: Let your agent trigger workflows inside your Bubble app to automate complex business processes based on real-time prompts or events. - Dynamic data queries: Effortlessly ask your agent to fetch, filter, or search records from any data type within your Bubble app and return structured results. - User account administration: Enable your agent to create, update, or manage user profiles, permissions, and authentication flows directly in your Bubble environment. - App configuration and resource management: Allow your agent to adjust application settings, manage resources, or monitor usage metrics—keeping your Bubble project running smoothly. ## Supported Tools | Tool slug | Name | Description | |---|---|---| | `BUBBLE_DATA_BULK_CREATE_THINGS` | Bulk Create Things | Tool to bulk create multiple Things in Bubble via newline-separated JSON. Use when you need to insert many records at once. Must have Create via API permission. | | `BUBBLE_DATA_CREATE_THING` | Create Thing | Tool to create a new Thing. Use when providing a complete JSON payload to add a new record. | | `BUBBLE_DATA_DELETE_THING_BY_ID` | Delete Thing By ID | Tool to delete a Bubble Thing by its unique ID. Use when you need to remove a specific record via the Bubble Data API. | | `BUBBLE_DATA_GET_THING_BY_ID` | Get Thing By ID | Retrieves a single Thing (record) from a Bubble Data Type by its unique ID. This is a read-only operation that fetches complete details of a specific record. The response includes all custom fields defined in the Data Type, plus standard Bubble fields (_id, created_by, created_date, modified_date). Use when you need to: - Fetch details of a specific record you know the ID of - Verify a record exists - Get the latest field values for a Thing Note: Requires the Data API to be enabled in your Bubble app settings and the specific Data Type to be exposed via the API. | | `BUBBLE_DATA_PATCH_THING_BY_ID` | Patch Thing By ID | Tool to modify selected fields on a Thing by its unique ID. Use after confirming the Thing exists. | | `BUBBLE_DATA_PUT_REPLACE_THING_BY_ID` | Replace Thing by ID | Tool to replace all editable fields on a Thing by its Unique ID.

Pass any required parameters as a JSON object in the parameters field. | ## Supported Triggers None listed. ## Creating MCP Server - Stand-alone vs Composio SDK The Bubble MCP server is an implementation of the Model Context Protocol that connects your AI agent to Bubble. It provides structured and secure access so your agent can perform Bubble operations on your behalf through a secure, permission-based interface. 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: - Node.js 18 or higher - A Composio account with an active API key - An OpenAI API key - Basic familiarity with TypeScript ### 1. Getting API Keys for OpenAI and Composio OpenAI API Key - Go to the [OpenAI dashboard](https://platform.openai.com/settings/organization/api-keys) and create an API key. - You need credits or a connected billing setup to use the models. - Store the key somewhere safe. Composio API Key - Log in to the [Composio dashboard](https://dashboard.composio.dev?utm_source=toolkits&utm_medium=framework_docs). - Go to Settings and copy your API key. - This key lets your Mastra agent talk to Composio and reach Bubble through MCP. ### 2. Install dependencies Install the required packages. What's happening: - @composio/core is the Composio SDK for creating MCP sessions - @mastra/core provides the Agent class - @mastra/mcp is Mastra's MCP client - @ai-sdk/openai is the model wrapper for OpenAI - dotenv loads environment variables from .env ```bash npm install @composio/core @mastra/core @mastra/mcp @ai-sdk/openai dotenv ``` ### 3. Set up environment variables Create a .env file in your project root. What's happening: - COMPOSIO_API_KEY authenticates your requests to Composio - COMPOSIO_USER_ID tells Composio which user this session belongs to - OPENAI_API_KEY lets the Mastra agent call OpenAI models ```bash COMPOSIO_API_KEY=your_composio_api_key_here COMPOSIO_USER_ID=your_user_id_here OPENAI_API_KEY=your_openai_api_key_here ``` ### 4. Import libraries and validate environment What's happening: - dotenv/config auto loads your .env so process.env.* is available - openai gives you a Mastra compatible model wrapper - Agent is the Mastra agent that will call tools and produce answers - MCPClient connects Mastra to your Composio MCP server - Composio is used to create a Tool Router session ```typescript import "dotenv/config"; import { openai } from "@ai-sdk/openai"; import { Agent } from "@mastra/core/agent"; import { MCPClient } from "@mastra/mcp"; import { Composio } from "@composio/core"; import * as readline from "readline"; import type { AiMessageType } from "@mastra/core/agent"; const openaiAPIKey = process.env.OPENAI_API_KEY; const composioAPIKey = process.env.COMPOSIO_API_KEY; const composioUserID = process.env.COMPOSIO_USER_ID; if (!openaiAPIKey) throw new Error("OPENAI_API_KEY is not set"); if (!composioAPIKey) throw new Error("COMPOSIO_API_KEY is not set"); if (!composioUserID) throw new Error("COMPOSIO_USER_ID is not set"); const composio = new Composio({ apiKey: composioAPIKey as string, }); ``` ### 5. Create a Tool Router session for Bubble What's happening: - create spins up a short-lived MCP HTTP endpoint for this user - The toolkits array contains "bubble" for Bubble access - session.mcp.url is the MCP URL that Mastra's MCPClient will connect to ```typescript async function main() { const session = await composio.create( composioUserID as string, { toolkits: ["bubble"], }, ); const composioMCPUrl = session.mcp.url; console.log("Bubble MCP URL:", composioMCPUrl); ``` ### 6. Configure Mastra MCP client and fetch tools What's happening: - MCPClient takes an id for this client and a list of MCP servers - The headers property includes the x-api-key for authentication - getTools fetches the tool definitions exposed by the Bubble toolkit ```typescript const mcpClient = new MCPClient({ id: composioUserID as string, servers: { nasdaq: { url: new URL(composioMCPUrl), requestInit: { headers: session.mcp.headers, }, }, }, timeout: 30_000, }); console.log("Fetching MCP tools from Composio..."); const composioTools = await mcpClient.getTools(); console.log("Number of tools:", Object.keys(composioTools).length); ``` ### 7. Create the Mastra agent What's happening: - Agent is the core Mastra agent - name is just an identifier for logging and debugging - instructions guide the agent to use tools instead of only answering in natural language - model uses openai("gpt-5") to configure the underlying LLM ```typescript const agent = new Agent({ name: "bubble-mastra-agent", instructions: "You are an AI agent with Bubble tools via Composio.", model: "openai/gpt-5", }); ``` ### 8. Set up interactive chat interface What's happening: - messages keeps the full conversation history in Mastra's expected format - agent.generate runs the agent with conversation history and Bubble toolsets - maxSteps limits how many tool calls the agent can take in a single run - onStepFinish is a hook that prints intermediate steps for debugging ```typescript let messages: AiMessageType[] = []; console.log("Chat started! Type 'exit' or 'quit' to end.\n"); const rl = readline.createInterface({ input: process.stdin, output: process.stdout, prompt: "> ", }); rl.prompt(); rl.on("line", async (userInput: string) => { const trimmedInput = userInput.trim(); if (["exit", "quit", "bye"].includes(trimmedInput.toLowerCase())) { console.log("\nGoodbye!"); rl.close(); process.exit(0); } if (!trimmedInput) { rl.prompt(); return; } messages.push({ id: crypto.randomUUID(), role: "user", content: trimmedInput, }); console.log("\nAgent is thinking...\n"); try { const response = await agent.generate(messages, { toolsets: { bubble: composioTools, }, maxSteps: 8, }); const { text } = response; if (text && text.trim().length > 0) { console.log(`Agent: ${text}\n`); messages.push({ id: crypto.randomUUID(), role: "assistant", content: text, }); } } catch (error) { console.error("\nError:", error); } rl.prompt(); }); rl.on("close", async () => { console.log("\nSession ended."); await mcpClient.disconnect(); process.exit(0); }); } main().catch((err) => { console.error("Fatal error:", err); process.exit(1); }); ``` ## Complete Code ```typescript import "dotenv/config"; import { openai } from "@ai-sdk/openai"; import { Agent } from "@mastra/core/agent"; import { MCPClient } from "@mastra/mcp"; import { Composio } from "@composio/core"; import * as readline from "readline"; import type { AiMessageType } from "@mastra/core/agent"; const openaiAPIKey = process.env.OPENAI_API_KEY; const composioAPIKey = process.env.COMPOSIO_API_KEY; const composioUserID = process.env.COMPOSIO_USER_ID; if (!openaiAPIKey) throw new Error("OPENAI_API_KEY is not set"); if (!composioAPIKey) throw new Error("COMPOSIO_API_KEY is not set"); if (!composioUserID) throw new Error("COMPOSIO_USER_ID is not set"); const composio = new Composio({ apiKey: composioAPIKey as string }); async function main() { const session = await composio.create(composioUserID as string, { toolkits: ["bubble"], }); const composioMCPUrl = session.mcp.url; const mcpClient = new MCPClient({ id: composioUserID as string, servers: { bubble: { url: new URL(composioMCPUrl), requestInit: { headers: session.mcp.headers, }, }, }, timeout: 30_000, }); const composioTools = await mcpClient.getTools(); const agent = new Agent({ name: "bubble-mastra-agent", instructions: "You are an AI agent with Bubble tools via Composio.", model: "openai/gpt-5", }); let messages: AiMessageType[] = []; const rl = readline.createInterface({ input: process.stdin, output: process.stdout, prompt: "> ", }); rl.prompt(); rl.on("line", async (input: string) => { const trimmed = input.trim(); if (["exit", "quit"].includes(trimmed.toLowerCase())) { rl.close(); return; } messages.push({ id: crypto.randomUUID(), role: "user", content: trimmed }); const { text } = await agent.generate(messages, { toolsets: { bubble: composioTools }, maxSteps: 8, }); if (text) { console.log(`Agent: ${text}\n`); messages.push({ id: crypto.randomUUID(), role: "assistant", content: text }); } rl.prompt(); }); rl.on("close", async () => { await mcpClient.disconnect(); process.exit(0); }); } main(); ``` ## Conclusion You've built a Mastra AI agent that can interact with Bubble through Composio's Tool Router. You can extend this further by: - Adding other toolkits like Gmail, Slack, or GitHub - Building a web-based chat interface around this agent - Using multiple MCP endpoints to enable cross-app workflows ## How to build Bubble MCP Agent with another framework - [OpenAI Agents SDK](https://composio.dev/toolkits/bubble/framework/open-ai-agents-sdk) - [Claude Agent SDK](https://composio.dev/toolkits/bubble/framework/claude-agents-sdk) - [Claude Code](https://composio.dev/toolkits/bubble/framework/claude-code) - [Claude Cowork](https://composio.dev/toolkits/bubble/framework/claude-cowork) - [Codex](https://composio.dev/toolkits/bubble/framework/codex) - [OpenClaw](https://composio.dev/toolkits/bubble/framework/openclaw) - [Hermes](https://composio.dev/toolkits/bubble/framework/hermes-agent) - [CLI](https://composio.dev/toolkits/bubble/framework/cli) - [Google ADK](https://composio.dev/toolkits/bubble/framework/google-adk) - [LangChain](https://composio.dev/toolkits/bubble/framework/langchain) - [Vercel AI SDK](https://composio.dev/toolkits/bubble/framework/ai-sdk) - [LlamaIndex](https://composio.dev/toolkits/bubble/framework/llama-index) - [CrewAI](https://composio.dev/toolkits/bubble/framework/crew-ai) ## Related Toolkits - [Supabase](https://composio.dev/toolkits/supabase) - Supabase is an open-source backend platform offering scalable Postgres databases, authentication, storage, and real-time APIs.

With a standalone Bubble MCP server, the agents and LLMs can only access a fixed set of Bubble tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from Bubble and many other apps based on the task at hand, all through a single MCP endpoint. ### Can I use Tool Router MCP with Mastra AI? Yes, you can. Mastra AI 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 Bubble tools. ### Can I manage the permissions and scopes for Bubble while using Tool Router? Yes, absolutely. You can configure which Bubble 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 Bubble data and credentials are handled as safely as possible. --- [See all toolkits](https://composio.dev/toolkits) · [Composio docs](https://docs.composio.dev/llms.txt)
