Allied EraThe Short Version
MCP (Model Context Protocol) is an open standard that lets AI assistants connect to business systems — like Salesforce — in a safe, consistent way.
A simple way to picture it: MCP is like a universal plug for AI. Before USB, every device needed its own special cable. Before MCP, every AI tool needed its own custom integration for every system. MCP gives them one common way to connect.
Why Should a Business Care?
AI assistants are very good at reading, writing, and reasoning. But on their own, they know nothing about your customers, deals, or cases. Without a connection, your team ends up copying data out of Salesforce, pasting it into an AI tool, and copying the answer back. That is slow, and it risks sensitive data ending up in the wrong place.
With MCP, an AI assistant can:
- Read live data — "Which of my opportunities close this month and have no activity in two weeks?"
- Take approved actions — "Create a follow-up task for each of them."
- Work across systems — combine Salesforce with other connected tools, such as documents or a calendar
All of this happens in plain language, without anyone writing a report or a SOQL query.
How MCP Works (In Plain English)
There are two sides to every MCP connection:
| Part | What it is | Example |
|---|---|---|
| MCP client | The AI app your team uses | Claude, or an AI agent |
| MCP server | The connector that exposes a system's data and actions | A Salesforce MCP server |
The server tells the AI what tools it offers (for example, "search records" or "create a task"). When a user asks a question, the AI decides which tool to use, the server runs it in Salesforce, and the AI explains the result.
MCP and Salesforce Today
Salesforce now offers hosted MCP servers that admins can switch on in Setup. They let MCP-compatible AI apps, such as Claude, work with Salesforce data. Admins can also build custom MCP tools from things Salesforce teams already use — such as autolaunched Flows and invocable Apex actions — so the AI follows the same business logic as the rest of the org.
For developers, there is also a Salesforce DX MCP server that helps AI coding assistants work with Salesforce projects.
Is It Secure?
Security is the first question to ask, and MCP with Salesforce is designed around it:
- Users sign in with OAuth. Nobody shares passwords with the AI.
- Salesforce permissions still apply. The AI can only see and change what the signed-in user is allowed to. A sales rep's AI cannot read HR records the rep can't see.
- Admins control access. Admins decide which apps may connect and which MCP servers and tools are switched on.
What to watch for: an AI connected to real data is powerful, so start with read-only tools, give access to a small group first, and check what the AI does before you allow it to create or update records.
MCP vs Traditional Integrations
| Traditional integration | MCP | |
|---|---|---|
| Built for | One fixed process (e.g., sync orders nightly) | Flexible, question-driven work with AI |
| Who uses it | Systems talking to systems | People asking an AI in plain language |
| Effort to reuse | New build for each tool | One server works with any MCP-compatible AI app |
MCP doesn't replace your existing integrations. Nightly syncs and system-to-system APIs still have their place. MCP adds a new layer: letting people work with your data through AI.
What Can Your Team Do With It?
- Sales: "Summarize my top 10 deals and tell me which ones are at risk."
- Service: "Show open high-priority cases for this account and draft a status update for the customer."
- Managers: "How many new leads came from the website this week, and how many were contacted?"
- Admins: "Which validation rules are active on the Opportunity object?"
Next Step
If you want to try MCP, start with a sandbox, a small pilot group, and read-only access. Our step-by-step guide on connecting Claude to Salesforce with MCP walks through the setup.
