PostgreSQL Multi-Schema offers read-only access with advanced schema support for secure query execution and multi-namesp
Provides read-only access to PostgreSQL databases with the ability to specify and isolate multiple schemas for secure cross-schema querying.
PostgreSQL Multi-Schema is a community-built MCP server published by harjjotsinghh that provides AI assistants with tools and capabilities via the Model Context Protocol. PostgreSQL Multi-Schema offers read-only access with advanced schema support for secure query execution and multi-namesp It is categorized under databases, analytics data.
You can install PostgreSQL Multi-Schema in your AI client of choice. Use the install panel on this page to get one-click setup for Cursor, Claude Desktop, VS Code, and other MCP-compatible clients. This server runs locally on your machine via the stdio transport.

PostgreSQL Multi-Schema is released under the MIT license. This is a permissive open-source license, meaning you can freely use, modify, and distribute the software.
Enable Claude to query your database directly using natural language
Example
Ask 'Show me top 10 customers by revenue this month' and get SQL results instantly
Eliminate manual SQL writing for ad-hoc queries, get insights 10x faster
Generate complex reports and analytics without leaving conversation
Example
Analyze sales trends, cohort retention, user behavior patterns conversationally
Democratize data access—non-technical team members can query databases
Understand database structure, relationships, and data models
Example
'Explain the user_orders table schema and its relationships'
Onboard engineers faster, explore unfamiliar databases efficiently
Share your MCP server with the developer community
PostgreSQL Multi-Schema has been reliable for tool-calling workflows; the MCP profile page is a good permalink for internal docs.
Useful MCP listing: PostgreSQL Multi-Schema is the kind of server we cite when onboarding engineers to host + tool permissions.
PostgreSQL Multi-Schema is a well-scoped MCP server in the explainx.ai directory — install snippets and categories matched our Claude Code setup.
We evaluated PostgreSQL Multi-Schema against two servers with overlapping tools; this profile had the clearer scope statement.
We wired PostgreSQL Multi-Schema into a staging workspace; the listing’s GitHub and npm pointers saved time versus hunting across READMEs.

Strong directory entry: PostgreSQL Multi-Schema surfaces stars and publisher context so we could sanity-check maintenance before adopting.
I recommend PostgreSQL Multi-Schema for teams standardizing on MCP; the explainx.ai page compares cleanly with sibling servers.

A Model Context Protocol server that provides read-only access to PostgreSQL databases with enhanced multi-schema support. This server enables LLMs to inspect database schemas across multiple namespaces and execute read-only queries while maintaining schema isolation.
sql (string): The SQL query to executeThe server provides schema information for each table across authorized schemas:
postgres://<host>/<db_schema>/<table>/schema)
The server requires a database URL and accepts a comma-separated list of schemas to expose:
npx -y mcp-server-postgres-multi-schema <database-url> [schemas]
postgresql://localhost/mydb)# Connect with default public schema
npx -y mcp-server-postgres-multi-schema postgresql://localhost/mydb
# Connect with multiple schemas
npx -y mcp-server-postgres-multi-schema postgresql://localhost/mydb public,analytics,staging
Configure the "mcpServers" section in your claude_desktop_config.json:
{
"mcpServers": {
"postgres": {
"command": "npx",
"args": [
"-y",
"mcp-server-postgres-multi-schema",
"postgresql://localhost/mydb",
"public,audit"
]
}
}

💡 Pro Tips
Architecture
MCP server acts as bridge between Claude and database, translating natural language to SQL queries and returning results in structured format.
Protocols
Compatibility
✓ Use when
Use for ad-hoc data queries, exploratory analysis, report generation, schema exploration, and democratizing data access. Best for read-heavy analytics workloads.
✗ Avoid when
Avoid for production write operations, mission-critical transactions, real-time OLTP workloads, or when database contains sensitive PII without proper access controls. Use read replicas, not primary.
