Questions

What is the Oracle Access MCP server?

Model Context Protocol server to access oracle database

What tools does Oracle Access expose?

6 in total: 2 read-only, 2 that write, and 2 that can delete or overwrite (exec_ddl_sql, exec_dml_sql). Every one is listed on this page with its risk.

Is Oracle Access safe to connect to an agent?

The audit found nothing in the source that contradicts what it says it does, and graded it B (89/100). Grade A is held back for packages that have also passed a sandboxed behavioural run, which is why a clean server reads B. Separately from the audit: 2 of its tools can destroy data, so scope the token you give it to what you actually need.

What credentials does Oracle Access need?

No credential environment variables were found in its source, so it appears to need none.

How does Oracle Access run?

It speaks stdio, so it runs as a local process your client starts. It is published on npm as mcp-server-oracle at 1.0.1.

How current is this page?

The grade is for one exact copy of the source (e4d341ab8070), read on 2026-10-09. The repository is watched and re-audited when it changes.
