Which MCP Server Should You Choose?
Choose Dbridge MCP when:
You need dedicated capabilities in the Databases domain.
You prefer local stdio subprocess transport architecture.
Your security boundary fits: other (Free / Open Source).
Query SQLite, PostgreSQL, and MySQL in plain language — read-only by design, with column hiding/masking, row caps, per-query timeouts, cost-based rejection, and rate limiting.
MCP server for secure database access (PostgreSQL, MySQL, SQLite) with parameterized queries and schema inspection
Dbridge MCP is categorized under Databases and uses a local stdio subprocess. In contrast, MCP Datalink belongs to Databases using local stdio subprocess. Select Dbridge MCP when you need capabilities focused on databases and MCP Datalink when you require tools for databases.
Per-column distinct-value counts and null fractions — is this column selective enough to index?
index_health
List indexes with sizes and scan counts, flagging unused, duplicate, and invalid ones.
test_index
Simulate a `CREATE INDEX` without building it and report whether the planner would use it (PostgreSQL, via [hypopg](https://github.com/HypoPG/hypopg)).
slow_queries
The most expensive recorded statements with call counts and timings (PostgreSQL `pg_stat_statements`, MySQL `performance_schema`).
get_limits
Report the safety limits in effect (caps, timeouts, hidden/masked columns).
