How to Use the COR MCP in Mastra AI

Q: What tool should I use to verify my connection status?

Run the checkcorstatus tool. It returns a quick health check of the API, letting your agent confirm the integration is live before running complex workflows.

Build resilient, self-healing agency workflows using Mastra AI and the COR MCP Server.

Perplexity

Resilient project creation with Mastra AI

The `create_cor_project` tool enables automated, multi-step onboarding workflows that handle API hiccups gracefully. If a project creation step fails due to network issues, Mastra's workflow engine automatically retries the operation with exponential backoff. This ensures your agency operations never stall. Your automated setup scripts run reliably in the background, verifying success with `get_cor_project` before moving to the next step.

Automated time auditing workflows

The `list_cor_time_entries` tool acts as the data source for your automated auditing agents. Mastra AI processes these entries through conditional branches, flagging missing logs or unusual margin dips without human intervention. If an entry violates your agency's budget limits, the system triggers a warning. You can configure a human-in-the-loop approval step before any changes write back to the server.

Team workload balancing via MCP Server

The `list_cor_team_users` tool pulls live team rosters into your Mastra agent to analyze resource distribution. Your automated workflow maps out which team members are overallocated across active client projects. By cross-referencing `list_cor_teams`, the agent moves tasks between teams dynamically. It handles the entire restructuring process, keeping project managers updated via automated Slack pings.

Setup guide

Set up COR MCP in Mastra AI

Prerequisites

Node.js 18+ and a TypeScript project
@mastra/mcp + @mastra/core packages
Active Vinkius subscription with a valid endpoint token

1

Install dependencies
Run npm install @mastra/mcp @mastra/core plus your preferred model provider (e.g. @ai-sdk/openai).
2

Configure the MCPClient
Create an MCPClient with your Vinkius endpoint as a URL object. 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's tools object. All COR tools become native Mastra tools.
4

Run with any model
Swap openai("gpt-4o") for any AI SDK-compatible provider. Call agent.generate() and the agent routes tool calls through MCP automatically.

agent.ts

import { MCPClient } from "@mastra/mcp";
import { Agent } from "@mastra/core/agent";
import { openai } from "@ai-sdk/openai";

const mcpClient = new MCPClient({
  id: "cor-mcp-client",
  servers: {
    "cor-mcp": {
      url: new URL(
        "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
      ),
    },
  },
});

const agent = new Agent({
  name: "COR Agent",
  model: openai("gpt-4o"),
  instructions: "You have access to COR tools.",
  tools: {
    ...(await mcpClient.listTools()),
  },
});

const result = await agent.generate(
  "List recent COR transactions"
);
console.log(result.text);

Common questions about COR MCP in Mastra AI

Initialize the MCP client with your Vinkius URL, call listTools(), and spread those tools directly into your agent's configuration. Mastra handles the underlying transport automatically.

Yes, you can set requireToolApproval on critical actions like project creation. This pauses the workflow and waits for an admin's green light before executing the tool after setting standard MCP permissions.

Mastra's built-in workflow engine catches rate limit errors and applies automatic retries. This keeps your agent running smoothly even during heavy batch operations like listing all team tasks using this MCP Server setup.

Run the `check_cor_status` tool. It returns a quick health check of the API, letting your agent confirm the integration is live before running complex workflows.

Every request for team logs and project metadata is processed in an isolated, zero-trust sandbox. Your credentials are encrypted at rest and never shared with external LLM providers.
