MCP Server
An MCP server is an open‑standard service that exposes tools and resources to AI clients using the Model Context Protocol. It lets AI models retrieve live data and perform actions—securely and consistently—against systems like file stores, APIs, and development platforms.
In depth
The Model Context Protocol (MCP) defines a universal way for AI clients (for example, desktop agents or hosted assistants) to request and use external capabilities. An MCP server implements that protocol and presents a catalog of tools (functions the AI can call, such as “create document” or “run query”) and resources (data the AI can read or modify, like files or database rows).
Instead of each AI client building custom integrations for every service, the MCP server centralizes the integration logic. The server handles authentication, authorization, input validation, and the concrete API calls needed to interact with third‑party systems. From the AI’s perspective, those diverse capabilities look like a single, well‑documented interface.
That standardization makes two important things possible: first, AI agents become more grounded—responses are backed by live, relevant data and actions. Second, teams retain control—access is audited and scoped, and sensitive credentials never need to be embedded directly inside the model.
How it works
Standardized protocol: MCP defines the messages, capabilities, and discovery mechanics AI clients use to find and call server tools. This creates a consistent developer experience across platforms.
Tools and resources: The server publishes a list of available tools (for example, “search files,” “call payments API,” or “open pull request”) and the resources those tools operate on.
Secure access: The MCP server enforces security policies—OAuth flows, API keys, role checks, encryption, and audit logs—so the AI uses external systems without exposing sensitive credentials.
Data accessibility: AI clients query the MCP server for fresh data or to trigger actions, allowing the model to give timely, actionable outputs rather than generic responses.
Key examples
File system server: Lets an AI read, write and organize files on a device or shared storage (for example, to draft a report or find a contract).
API servers: Provide connectors to external services such as CRMs, billing systems or databases so an AI can pull records, compute aggregates, or start workflows.
Development tools: Servers can expose GitHub or CI/CD actions so an AI can open issues, create branches, or suggest code changes.
Vertical systems: Healthcare, finance or HR MCP adapters let AI interact with domain‑specific APIs while respecting compliance and auditing requirements.
Benefits
Grounded AI: AI responses tie directly to real data and current states, so decisions and outputs are more reliable.
Enhanced capabilities: Models can perform real tasks—generate documents, run queries, update records—rather than only suggesting what to do.
Secure integration: Sensitive credentials and access policies stay on the server side, reducing risk and simplifying governance.
Interoperability: Multiple AI clients and platforms can share the same MCP server, enabling consistent behaviour across tools.
Pro tip
Avoid giving AI agents blanket privileges. Use least‑privilege access, short‑lived tokens and fine‑grained tool whitelists so models can only perform approved actions. Add logging and human‑in‑the‑loop approvals for high‑risk operations.
Why it matters
AI is most useful when it’s connected to the systems people actually use. An MCP server makes those connections practical and safe. For businesses, that means faster automation, fewer manual handoffs and more trustworthy AI outputs. For data teams, it provides a governed integration layer that preserves security and auditability while enabling product teams and business users to build AI‑driven workflows.
MCP Server - In practice
A marketing manager asks an AI assistant to build a weekly dashboard. The assistant queries the MCP server for the latest campaign data, assembles charts and places the new dashboard in the shared folder.
An engineering lead asks an AI to prepare a release checklist. The assistant uses an MCP GitHub connector to list open PRs and open issues, then drafts the checklist and opens a pull request.
A support agent asks an AI to find a customer’s billing history. The assistant retrieves records from a payments API via the MCP server, summarizes relevant charges, and suggests next steps—all without exposing raw credentials.
Product‑specific notes
PowerMetrics is built to be AI‑ready with a metric‑centric foundation. An MCP server complements PowerMetrics by enabling secure, standardized access to live metrics, dashboards and external data sources for AI assistants. Practical uses include:
Letting the PowerMetrics Assistant pull current metric values or historical trends to answer business questions.
Enabling automated report generation that combines PowerMetrics dashboards with external documents or CRM data.
In future, this may include controlled actions—like refreshing a data source or publishing a view—while keeping permissions and credentials managed by the MCP server.
These integrations help teams trust AI outputs and move from “insight” to “action” faster.

Knowledge Graph
A knowledge graph is a structured network that represents real-world entities (people, places, products, metrics) and the relationships between them. It adds context and meaning to data, so systems and people can make smarter, more reliable decisions rather than just matching keywords or numbers.

Data governance is the system of people, policies, and tools that keeps data accurate, secure, and usable across your company. Think of it like hiring a skilled librarian for a massive library. Every book is cataloged, protected, and easy to find, so readers trust what they pick up and can act quickly. With solid governance, your team works from the same definitions, follows clear rules for access and use, and treats data as a business asset.
