🛡️🔌MCP Servers

MCP (Model Context Protocol) servers enable external tools to integrate with LLMs (Large Language Models). These servers define what tools are available to the assistant and how to interact with third-party services like Slack, Stripe, Google Sheets, and more. Think of MCP servers as a bridge between Blockli Assistant and external APIs—allowing for actions like sending a message to Slack or processing a Stripe payment, directly through conversational AI.

Blockli Assistant connects to third-party services on your behalf to automate tasks and power intelligent workflows. For example:

• Slack: Posting updates to channels

• Stripe: Retrieving payment history

• Google Sheets: Updating spreadsheets based on actions

These actions are made possible through remote MCP servers that securely manage tool definitions and API communication.

To protect your data and ensure system integrity, Blockli Assistant only connects to official MCP servers hosted by the service providers themselves. This means:

✅ We use mcp.stripe.com for Stripe,

✅ mcp.slack.com for Slack (if available),

✅ And similarly trusted domains for other supported services.

We do not connect to third-party proxy MCP servers—no exceptions.

Unofficial or third-party MCP servers may:

• Include hidden prompt injections that manipulate AI behavior.

• Request sensitive data you didn’t intend to share.

• Update tool definitions silently, introducing unexpected behavior.

OpenAI’s recommendation is clear: “Only connect to servers you know and trust.” That’s why Blockli has adopted a strict policy of MCP whitelisting—we only use official, provider-operated MCP servers.

Your trust and data privacy are critical to us. Blockli Assistant is built with security by design, and our MCP usage reflects that. Every integration is vetted, and every tool runs through servers operated by the services themselves—never middlemen.
