Common questions about MCP servers for databases
- What are the most popular MCP servers for databases?
- By GitHub stars: CodeGraphContext (4,354 stars), dbhub (3,702 stars), postgres-mcp (3,420 stars), butterbase (3,031 stars), mcp-crawl4ai-rag (2,268 stars). Stars measure popularity, not quality, so read what each one reaches and how it is maintained.
- What do MCP servers for databases connect to?
- Among those placed here, the most common things they say they reach are sqlite (45 servers), mysql (32 servers), postgres (31 servers), postgresql (28 servers), neo4j (19 servers), supabase (13 servers), mongodb (9 servers), bigquery (8 servers).
- Which MCP servers for databases need a credential?
- 114 of 260 name a credential in their source; the most common are NEO4J_PASSWORD (18), DB_PASSWORD (12), MYSQL_PASSWORD (8), POSTGRES_PASSWORD (8), SNOWFLAKE_PASSWORD (5). A server with no credential listed has not been shown to need none; check its README.
- Are there official MCP servers for databases?
- Yes: butterbase is named as a vendor’s own server.
- How are servers placed under databases?
- By a stated rule over what each one declares it reaches and what it says it does, never by a classifier. A server can sit in no category when no rule fired, which does not mean it belongs nowhere.
