Available components
How this component scores in each security and reliability category. Every signal is checked automatically from public evidence about the published package, including repeated runs of it in an isolated sandbox, and we only credit what we can confirm. How we score → Why this is hard to score →

How do I install the SQL MCP server?
SQL runs locally as an npm package, launched with npx -y @abhishekmcp/sql. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

Provenance No attestation
The registry publishes no build provenance for this version, so there is nothing to verify.

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →

What is the SQL MCP server?
SQL is an MCP server listed in the public MCP registry as io.github.Abhishekkumar2021/sql. Read-only SQL querying + schema introspection over Postgres & SQLite, with a gated write mode. This page covers its npm package (@abhishekmcp/sql).
Is the SQL MCP server safe to use?
SQL scores 82 out of 100 on VerifyMCP. We found no known CVEs affecting it as of 20 September 2026. It declares no install or post-install scripts. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.
What tools does the SQL MCP server expose?
SQL exposes 9 tools: list_connections, list_schemas, list_tables, describe_table, list_indexes, and 4 more. Their descriptions and schemas cost roughly 428 tokens of context every time the server is loaded.
Is the SQL MCP server still maintained?
SQL is still listed as active in the MCP registry. We last reached this channel on 20 September 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
What licence is the SQL MCP server under?
SQL declares the MIT licence, which is OSI-approved. That covers the source only, and says nothing about the cost of any service it calls.
