The best MCP servers for data access

Data access MCP servers let agents query databases, inspect schemas, and summarize results. These are the most popular options.

What this list covers

Data MCP servers give an AI agent a structured view of your data. Postgres and SQLite servers let the agent query relational stores. MongoDB and Redis servers handle document and key-value data. Stripe and Supabase servers wrap managed services. Most servers support read-only access by default with explicit scopes for writes, which keeps the data layer safe.

  • Postgres MCP for read-only and scoped-write SQL access
  • MongoDB MCP for document-shaped data
  • Redis MCP for ephemeral state, queues, and rate limiting
  • Supabase MCP for managed Postgres, auth, and storage
  • Stripe MCP for billing context in support workflows

Frequently asked questions

Are MCP database servers safe to use?

Most MCP database servers default to read-only access. For write access, you can scope a database user to specific tables or use a separate read replica. MCP Haus recommends the read-only-by-default pattern.

Which database MCP should I start with?

Start with the MCP server for the database you use most. If you use Postgres, the official Postgres MCP from the modelcontextprotocol/servers repo is a good default. If you use MongoDB, Redis, or SQLite, each has a dedicated MCP server.
