Mssql Reader
Safely let agents inspect Microsoft SQL Server with read-only MCP tools for schema discovery, profiling, and querying without DDL or destructive writes.
Overview
io.github.ConnorBritain/mssql-reader is a MCP server for the Build phase that provides read-only Microsoft SQL Server schema discovery, profiling, and safe querying for coding agents.
What is this MCP server?
- Read-only MCP surface: schema discovery, profiling, and safe querying only
- Reduces risk versus full mssql server when exploring production-like datasets
- Node package @connorbritain/mssql-mcp-reader (v0.3.1) with stdio transport
- Ideal companion for analytics, debugging, and API design sessions
- Same SQL Server focus as the writer/full variants without DDL or data mutation tools
- Read-only: schema discovery, profiling, safe querying (no DDL)
- Package @connorbritain/mssql-mcp-reader version 0.3.1
- Transport: stdio
What problem does it solve?
You want agent help understanding SQL Server data without handing it tools that can corrupt production or apply DDL by mistake.
Who is it for?
Builders connecting agents to staging or read replicas, or anyone learning an unfamiliar MSSQL codebase before enabling write tools.
Skip if: Local dev where you need migrations, seed scripts, or INSERT/UPDATE via MCP—use mssql-writer or full mssql instead.
What do I get? / Deliverables
After install, agents explore schemas, profile columns, and run read-only queries so your SQL and API plans reflect real structure with lower mutation risk.
- Accurate schema and profile context for agent-generated SQL and docs
- Read-only query results for debugging and validation
- Lower-risk MCP footprint on shared database instances
Recommended MCP Servers
Journey fit
Integrations and backend work need database context during Build; read-only access is the default safe pattern for agents touching real data. Integrations subphase fits MCP bridges that connect your agent stack to external systems like SQL Server with minimal blast radius.
How it compares
Read-only database MCP connector, not a full admin SQL Server skill pack or ETL pipeline product.
Common Questions / FAQ
Who is io.github.ConnorBritain/mssql-reader for?
Solo developers and small teams who need MCP agents to explore SQL Server schemas and run safe read queries without write or DDL capabilities.
When should I use io.github.ConnorBritain/mssql-reader?
Use it when mapping an existing database, drafting queries for features, or debugging read paths before granting write or DDL MCP servers.
How do I add io.github.ConnorBritain/mssql-reader to my agent?
Install @connorbritain/mssql-mcp-reader via npm, configure stdio in your MCP client, and supply read-only SQL credentials with least privilege.
