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 →

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.

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 78 out of 100 on VerifyMCP. We recorded 1 known advisory against it as of 5 November 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 5 November 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.
