How to Use the Beeceptor MCP in Mastra AI
Wire up resilient API testing workflows using Mastra AI to manage mock endpoints and state.
Works with every AI agent you already use
…and any MCP-compatible client
Connect Beeceptor MCP to Mastra AI
Create your Vinkius account to connect Beeceptor to Mastra AI and route execution through our secure gateway. The platform manages server hosting, runtime updates, and security layers. Configuration requires no manual server provisioning.
Conditional mock rule deployment
Testing payment gateways means simulating failures. Your Mastra AI workflow can use `create_rule` to force a 500 error, trigger the retry logic, and swap it back with `update_rule_partial`. The entire sequence runs automatically. If the test suite crashes, you need a clean environment. The agent catches the exception and executes `delete_all_rules` before the next run. Mastra handles the exponential backoff while the endpoint resets.
Stateful API simulation with Mastra AI
Complex integrations require persistent variables across multiple steps. Give your workflow access to `upsert_state` to store temporary tokens or transaction IDs. The next step in the chain reads that data via `get_state_item`. Scrubbing that state is just as critical. When a branch completes successfully, the agent calls `delete_state_item` to clean up. You never leave stale data lying around for the next test execution.
Manage mTLS via MCP Server
Secure webhook testing demands proper certificate handling. Mastra can manage this by calling `add_certificate` before initializing the secure connection. It verifies the setup and proceeds down the correct workflow branch. Keeping API definitions current takes constant effort. Build a sync job that checks for spec changes and pushes them using `upload_spec`. The agent monitors the import progress with `get_job_status` and alerts the team if it fails.
Set up Beeceptor MCP in Mastra AI
Prerequisites
- Node.js 18+ and a TypeScript project
-
@mastra/mcp+@mastra/corepackages - Active Vinkius subscription with a valid endpoint token
- 1
Install dependencies
Run
npm install @mastra/mcp @mastra/coreplus your preferred model provider (e.g.@ai-sdk/openai). - 2
Configure the MCPClient
Create an
MCPClientwith your Vinkius endpoint as aURLobject. Replace[YOUR_TOKEN_HERE]with your token from cloud.vinkius.com. - 3
Discover and inject tools
Call
mcpClient.listTools()and spread the result into your agent'stoolsobject. All Beeceptor tools become native Mastra tools. - 4
Run with any model
Swap
openai("gpt-4o")for any AI SDK-compatible provider. Callagent.generate()and the agent routes tool calls through MCP automatically.
import { MCPClient } from "@mastra/mcp";
import { Agent } from "@mastra/core/agent";
import { openai } from "@ai-sdk/openai";
const mcpClient = new MCPClient({
id: "beeceptor-mcp-client",
servers: {
"beeceptor-mcp": {
url: new URL(
"https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
),
},
},
});
const agent = new Agent({
name: "Beeceptor Agent",
model: openai("gpt-4o"),
instructions: "You have access to Beeceptor tools.",
tools: {
...(await mcpClient.listTools()),
},
});
const result = await agent.generate(
"List recent Beeceptor transactions"
);
console.log(result.text); Independent Platform Disclaimer: Vinkius is an independent platform and is not affiliated with, endorsed by, sponsored by, verified by, or otherwise authorized by Beeceptor.
