What Are MCP Servers & Connectors?
The Model Context Protocol standardizes how AI applications can connect with external capabilities.
The current MCP architecture distinguishes hosts, clients, and servers. Servers can expose capabilities that AI applications can discover and use.
Official MCP developer documentation describes three major server capability types: resources, tools, and prompts.

How to Choose the Right MCP Server or Connector
Start with the system being exposed.
Identify whether the server provides read-only data, executable tools, prompts, or a combination.
MCP tools can allow models to invoke external actions such as API calls, computations, or database queries. The current MCP specification describes tools as model-controlled capabilities exposed by servers.
That makes permissions extremely important.
Do not give a connector broader permissions than the AI application needs. A server that only needs product information should not automatically receive administrative order-management capabilities.
Check authentication and authorization carefully.
Also review the currently supported MCP protocol version because the standard continues to evolve. The official MCP project released a new specification on July 28, 2026, including substantial protocol changes.
Verify:
- Supported client environments
- Tools exposed
- Resource access
- Authentication
- Authorization
- Read versus write scope
- Transport/deployment
- Logging
- Error handling
- API limits
Credentials should never be embedded insecurely in distributed source files.
Review tool schemas carefully. Clear tool descriptions and structured parameters help clients understand how the connector should be used.
If the MCP server can create, update, delete, send, purchase, or modify business data, consider human-approval and confirmation boundaries.
Test the server with realistic inputs and failure cases.
Finally, review protocol compatibility, SDK requirements, external-system versions, hosting, environment configuration, documentation, licensing, update history, and seller support.
