Fastmcp Sqltools
Let your coding agent run SQL and inspect schema against PostgreSQL, MySQL, or SQLite without leaving the chat.
Overview
fastmcp-sqltools is an MCP server for the Build phase that gives coding agents SQL access to PostgreSQL, MySQL, and SQLite over stdio.
What is this MCP server?
- Stdio MCP server (fastmcp-sqltools 0.3.0) installable from PyPI
- PostgreSQL, MySQL, and SQLite in one server
- Agent-safe SQL access over Model Context Protocol
- Fits local dev and small-team databases without custom DB plugins
- Supports 3 SQL engines: PostgreSQL, MySQL, SQLite
- Transport: stdio MCP
- Package version 0.3.0 on PyPI (identifier fastmcp-sqltools)
What problem does it solve?
You keep context-switching to a SQL client or brittle scripts whenever the agent needs to read or verify data in your database.
Who is it for?
Indie builders with a local or staging Postgres, MySQL, or SQLite who want the agent to query and validate data during implementation.
Skip if: Teams that forbid agent database access, need only NoSQL/document stores, or want managed cloud DB consoles without MCP.
What do I get? / Deliverables
Your agent can run SQL and reason about schema through MCP so feature work and data checks stay in one workflow.
- MCP-registered SQL tool your agent can invoke
- Queryable access across three SQL engines from one server
- Faster schema and data validation during feature work
Recommended MCP Servers
Journey fit
Database wiring happens while you are building features and debugging data models, not during early idea research. This is an integration layer that connects agents to live SQL engines via MCP stdio, not a standalone app UI.
How it compares
MCP database bridge, not a migration runner or hosted analytics warehouse.
Common Questions / FAQ
Who is fastmcp-sqltools for?
Solo and small-team developers using MCP agents who need direct SQL against Postgres, MySQL, or SQLite while building.
When should I use fastmcp-sqltools?
Use it during build and integration work when you want the agent to inspect tables, run diagnostic queries, or verify data without leaving the agent session.
How do I add fastmcp-sqltools to my agent?
Install the fastmcp-sqltools package from PyPI, register it as an MCP stdio server in Claude Code or Cursor, and point it at your database connection settings.
