By the end, you'll have a working Bitwarden agent that can retrieve login details for salesforce account, list all shared vault items this week, generate a new secure password for dropbox through natural language commands. This guide will help you understand how to give your Mastra AI agent real control over a Bitwarden account through Composio's Bitwarden MCP server. Before we dive in, let's take a quick look at the key ideas and tools involved. ## Also integrate Bitwarden with - [OpenAI Agents SDK](https://composio.dev/toolkits/bitwarden/framework/open-ai-agents-sdk) - [Claude Agent SDK](https://composio.dev/toolkits/bitwarden/framework/claude-agents-sdk) - [Claude Code](https://composio.dev/toolkits/bitwarden/framework/claude-code) - [Claude Cowork](https://composio.dev/toolkits/bitwarden/framework/claude-cowork) - [Codex](https://composio.dev/toolkits/bitwarden/framework/codex) - [OpenClaw](https://composio.dev/toolkits/bitwarden/framework/openclaw) - [Hermes](https://composio.dev/toolkits/bitwarden/framework/hermes-agent) - [CLI](https://composio.dev/toolkits/bitwarden/framework/cli) - [Google ADK](https://composio.dev/toolkits/bitwarden/framework/google-adk) - [LangChain](https://composio.dev/toolkits/bitwarden/framework/langchain) - [Vercel AI SDK](https://composio.dev/toolkits/bitwarden/framework/ai-sdk) - [LlamaIndex](https://composio.dev/toolkits/bitwarden/framework/llama-index) - [CrewAI](https://composio.dev/toolkits/bitwarden/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 Bitwarden tools - Connect Mastra's MCP client to the Composio generated MCP URL - Fetch Bitwarden 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 Bitwarden 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 Bitwarden MCP server, and what's possible with it? The Bitwarden MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Bitwarden account. It provides structured and secure access to your encrypted vault, so your agent can perform actions like retrieving credentials, managing vault items, updating passwords, generating new secure passwords, and organizing your vault for you. - Secure credential retrieval: Instantly fetch login details, secure notes, or card information from your Bitwarden vault whenever your agent needs to access or autofill credentials. - Password management and updates: Direct your agent to update existing passwords, change login details, or rotate credentials for improved security. - Vault item creation and organization: Have your agent create new items—like logins, notes, or identities—and organize them into folders or collections for easy access and sharing. - Password generation and security checks: Use the agent to generate strong, unique passwords and even check for reused or weak credentials across your vault. - Automated sharing and access management: Let your agent securely share selected credentials with trusted users or teams, while maintaining detailed access controls. ## Supported Tools | Tool slug | Name | Description | |---|---|---| | `BITWARDEN_DELETE_GROUP` | Delete Group | Tool to delete a group. Use when you need to permanently remove a group by its ID after ensuring no dependencies exist. | | `BITWARDEN_DELETE_MEMBER` | Delete Member | Tool to delete a specific organization member. Use when you need to remove a member from the organization after verifying their member ID. | | `BITWARDEN_GET_GROUP_MEMBER_IDS` | Get Group Member IDs | Tool to retrieve the list of member IDs for a specific Bitwarden group. Use when you need only the user IDs of all members in a group. | | `BITWARDEN_GET_ORG_SUBSCRIPTION` | Get Organization Subscription | Tool to retrieve subscription details of the current organization. Use after obtaining a valid bearer token. | | `BITWARDEN_IMPORT_MEMBERS_AND_GROUPS` | Import Members and Groups | Tool to bulk import members and groups in a single request.

Use after obtaining a valid member ID to get full metadata. | | `BITWARDEN_UPDATE_MEMBER` | Update Member | Tool to update an organization member’s admin status. Use when toggling admin privileges for an existing member. | ## Supported Triggers None listed. ## Creating MCP Server - Stand-alone vs Composio SDK The Bitwarden MCP server is an implementation of the Model Context Protocol that connects your AI agent to Bitwarden. It provides structured and secure access so your agent can perform Bitwarden 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 Bitwarden 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 Bitwarden What's happening: - create spins up a short-lived MCP HTTP endpoint for this user - The toolkits array contains "bitwarden" for Bitwarden 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: ["bitwarden"], }, ); const composioMCPUrl = session.mcp.url; console.log("Bitwarden 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 Bitwarden 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: "bitwarden-mastra-agent", instructions: "You are an AI agent with Bitwarden 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 Bitwarden 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: { bitwarden: 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: ["bitwarden"], }); const composioMCPUrl = session.mcp.url; const mcpClient = new MCPClient({ id: composioUserID as string, servers: { bitwarden: { url: new URL(composioMCPUrl), requestInit: { headers: session.mcp.headers, }, }, }, timeout: 30_000, }); const composioTools = await mcpClient.getTools(); const agent = new Agent({ name: "bitwarden-mastra-agent", instructions: "You are an AI agent with Bitwarden 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: { bitwarden: 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 Bitwarden 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 Bitwarden MCP Agent with another framework - [OpenAI Agents SDK](https://composio.dev/toolkits/bitwarden/framework/open-ai-agents-sdk) - [Claude Agent SDK](https://composio.dev/toolkits/bitwarden/framework/claude-agents-sdk) - [Claude Code](https://composio.dev/toolkits/bitwarden/framework/claude-code) - [Claude Cowork](https://composio.dev/toolkits/bitwarden/framework/claude-cowork) - [Codex](https://composio.dev/toolkits/bitwarden/framework/codex) - [OpenClaw](https://composio.dev/toolkits/bitwarden/framework/openclaw) - [Hermes](https://composio.dev/toolkits/bitwarden/framework/hermes-agent) - [CLI](https://composio.dev/toolkits/bitwarden/framework/cli) - [Google ADK](https://composio.dev/toolkits/bitwarden/framework/google-adk) - [LangChain](https://composio.dev/toolkits/bitwarden/framework/langchain) - [Vercel AI SDK](https://composio.dev/toolkits/bitwarden/framework/ai-sdk) - [LlamaIndex](https://composio.dev/toolkits/bitwarden/framework/llama-index) - [CrewAI](https://composio.dev/toolkits/bitwarden/framework/crew-ai) ## Related Toolkits - [Borneo](https://composio.dev/toolkits/borneo) - Borneo is a data security and privacy platform for sensitive data discovery and remediation.

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