ldap_authenticate · Mcp Database MCP: Risk & Policy

WHAT IT DOES

What ldap_authenticate does on Mcp Database

AI agents invoke ldap_authenticate to trigger actions in Mcp Database. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.

WHY IT NEEDS A POLICY

Why ldap_authenticate needs a policy

This tool performs an authentication operation against an LDAP directory, triggering an external bind/authentication request. It doesn't merely read data passively — it executes an authentication transaction (LDAP bind) that involves credential verification and may log access attempts or trigger account lockout policies on repeated failure.

Verdict

ldap_authenticate Rate-limited

ldap_authenticate stays usable, but rate-capped — a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.
