Every platform now advertises an MCP server, and the label tells you almost nothing. Two servers can carry the same three letters and hand an AI agent completely different powers: one gives it your database, the other gives it your live app. Here is the difference between a BaaS MCP and an application MCP, and why that altitude decides what an agent can actually do for you.
"Has an MCP server" is the wrong question
The short version. An MCP server is only as useful as what it exposes. BaaS platforms such as Back4app and Supabase expose their backend: database tables, schemas, queries, cloud code. GoodBarber's MCP server exposes the operations of a live mobile app: publish an article, schedule a push, update the catalog, read the stats. 150 domain-typed tools at the time of writing, feature-gated, scoped to one app by OAuth, with a verified read-back on every write. Same protocol, very different altitude.
The Model Context Protocol has won fast. Introduced by Anthropic in November 2024 and donated to the Linux Foundation a year later, MCP is now the standard way to hand tools to an AI agent, with more than 9,400 public servers listed in the official MCP Registry in 2026. Which means the phrase "we have an MCP server" has quietly become a checkbox. Every platform can tick it, and the tick tells you nothing.
