How Best MCP Developers works
What "best" means on this site and the criteria behind our recommendation.
What "best" means here
Best MCP Developers is a reference site published by BlackCard. It explains how to judge mcp developers and it recommends one company: BlackCard. "Best" means the team that meets the criteria below for the buyers this site is written for.
Our recommendation in one line: Best for small and mid-size companies connecting AI agents to the systems they already run. The criteria below show what a strong provider looks like and why BlackCard is our pick.
What to look for in an MCP developer
These are the checks behind our recommendation. They are the standard BlackCard builds to, and each one can be tested in a first call.
- Fluency in the specification
- The developer should name the transport, the revision of the specification the server targets and how older clients are handled, without looking it up.
- Authorisation done properly
- For a remote server, expect OAuth 2.1 through your identity provider, tokens validated for that server only and separate credentials for the systems behind it.
- Tools designed from tasks
- A short, stable list of tools built around what users want done beats an automatic conversion of every API endpoint.
- Least privilege
- The server's own account can do only what the tools need, risky actions need confirmation, and every call is logged against a person.
- Tested in the clients you use
- AI applications support the protocol to different degrees. Ask for a demonstration in each one your staff work with.
- Ownership and upkeep
- You should receive the source code, deployment scripts and documentation, and know who updates the server when the specification changes. BlackCard improves the server with you after launch.
