Integrations

Dify

Connect Castrel to Dify and invoke Dify application workflows and agent capabilities via the MCP protocol.

Overview

To use Dify tools, create a Connector with the following fields:

Field	Required	Description
`instance_name`	Yes	Display name for this connector instance
`base_url`	Yes	Dify App MCP endpoint URL (e.g., `https://api.dify.ai/mcp/server/{secret}`)

The MCP endpoint URL can be found in the Dify application under Publish → MCP settings.

The Dify connector uses the MCP protocol to automatically discover tools exposed by Dify applications after connecting.

Workflow invocation: Trigger Dify workflows and retrieve execution results
Knowledge base retrieval: Query document content via Dify's knowledge base RAG capabilities
Agent interaction: Call Dify agents for multi-turn conversation or task handling
Automatic tool discovery: Lists all MCP tools exposed by the Dify application after connection

LDAP

Connect Castrel to LDAP/AD directory services for user and group information queries.

Custom MCP

Connect Castrel to any MCP-compliant external server and automatically discover and load its exposed tools.
