# Knowledge Base MCP Tools

> Use DialNexa knowledge base MCP tools through the remote MCP server.

DialNexa knowledge base MCP tools let an MCP-compatible AI client inspect and manage agent knowledge base containers. Each tool page includes its exact server description, input schema, safety level, request shape, and retry guidance.

## Before you call a tool

Connect with OAuth or a workspace API key and complete MCP initialization first. Use IDs exactly as another DialNexa tool returned them, including prefixes such as `agent_`, `call_`, and `workflow_`.

For operations that change data, verify the target and current state before the call. Billable and destructive tools require extra care because retrying an uncertain result can spend money or repeat an irreversible action.
