Oracle database MCP server using python-oracledb in thin mode — no Oracle Instant Client required.
Installation
No manual installation needed. Run directly with:
uvx mcp-oracle
Configuration
Add to your claude_desktop_config.json:
{
"mcpServers": {
"oracle": {
"command": "uvx",
"args": ["mcp-oracle"],
"env": {
"ORACLE_DSN": "host:1521/service_name",

}
}
}
}
DSN Format
| Format | Example | Use when |
|---|---|---|
host:port/service_name |
db.example.com:1521/ORCL |
Most modern Oracle databases |
host:port:SID |
db.example.com:1521:ORCL |
Legacy SID-based connections |
service_name vs SID: Modern Oracle databases use service names (check with your DBA). Use the / separator for service names and the : separator for SIDs.

Passschemafor cross-schema lookups.run_query— Execute aSELECTstatement and return results as JSON. Supports bind parameters via theparamsargument.
Table Name Case Sensitivity
Oracle stores identifiers in uppercase by default. describe_table("employees") and describe_table("EMPLOYEES") are equivalent — the server normalizes to uppercase automatically.
