MCP Explained for Executives: Model Context Protocol

Model Context Protocol has moved from an engineering topic to a board question in a short time, because it changes the economics and the governance of connecting AI agents to business systems. This explainer gives executives the business meaning: what MCP standardizes, why it lowers cost, where the control point is, and what risks to manage.

What problem does MCP solve?

Every AI agent needs to reach business systems: the CRM, the ERP, the ticketing platform, the document store. Without a standard, each agent project builds its own integrations, with its own credentials, its own error handling, and its own security review. The fifth agent repeats the work of the first, and IT ends up with dozens of unreviewed access paths.

Model Context Protocol is an open standard, introduced by Anthropic in late 2024 and since adopted broadly across model vendors and developer tooling, that defines how an agent discovers what a system offers and how it calls those capabilities. A company builds one MCP server per system; any approved agent uses it. FISTA's Model Context Protocol for the enterprise whitepaper covers the architecture; the glossary explains MCP vs API integration.

What does MCP change for the business?

Before MCP	With MCP
Custom integration per agent and per system	One governed server per system, reused by all agents
Credentials scattered across projects	Identity and permissions enforced at a gateway
Security review per integration	Review per server, once, with a catalog of approved servers
Lock-in to the agent platform's connectors	Broad support across vendors; connectors are portable
Integration is the schedule's critical path	Connectors exist before the agent project starts

The financial effect is that integration moves from a recurring project cost to a platform investment that appreciates as more agents use it. The MCP server development cost guide sets out the drivers.

Where is the control point?

Because every agent's tool call passes through MCP servers, the layer in front of them becomes the natural place to enforce policy. A gateway authenticates the agent, checks what it is authorized to do with each tool, logs every call with inputs and outputs, applies rate limits and budgets, and can block or require approval for consequential actions. This is the control point CISOs and CIOs have wanted for agents, and MCP creates it as a side effect of standardization. The how to build an MCP gateway playbook describes the implementation.

What are the risks?

MCP standardizes access, which means it standardizes the attack surface too:

• Malicious or compromised servers. An MCP server is a door into a system. Only approved, reviewed servers should be reachable by agents.
• Over-broad permissions. A server that exposes "do anything in the CRM" turns every agent using it into a privileged user. Tools should be narrow.
• Prompt injection through results. Data returned by a tool can contain text that manipulates the agent. Servers should sanitize, and agents should have limited authority regardless.
• Supply chain. Third-party MCP servers must be vetted like any dependency.

The MCP security risks guide covers each with controls; the executive takeaway is that MCP needs governance from day one, not after the first incident.

How should a company adopt MCP?

1. Inventory the systems agents will need and rank by value.
2. Build governed servers for the top two or three, with least-privilege tools and clear descriptions.
3. Stand up a gateway so every agent call is authenticated, authorized, and logged.
4. Maintain a catalog of approved servers; block everything else.
5. Review permissions on the same cycle as user access reviews.
6. Expand as agents demonstrate value, reusing servers across projects.

The MCP adoption checklist turns these steps into a review list, and how enterprise IT should govern MCP sets the operating model.

What does MCP mean for vendor strategy?

Because MCP is supported across model providers and agent tooling, connectors built to it are portable: a company that changes its model vendor or agent framework keeps its integration layer. That reduces the switching cost that used to make platform decisions feel permanent, and it strengthens the company's position in vendor negotiations. It also means integration investment compounds: each new agent starts with the connectors the last one built, which is why delivery time falls from the third agent onward.

What should executives ask?

• Which systems are exposed to agents through MCP today, and who approved each server?
• What can each server let an agent do, and is that the minimum needed?
• Does every call pass through a gateway with identity, authorization, and logging?
• How are third-party servers vetted?
• How much integration effort did MCP save on the last agent project?

How can FISTA Solutions help?

FISTA Solutions, an official Anthropic partner, builds governed MCP servers and gateways through its AI enablement practice, and builds the AI agents that use them with least-privilege tools and logging designed in. Since 2017, FISTA has delivered 150+ projects for 50+ companies across 12+ countries.
