About Discourse MCP Server
Integrate Discourse, the open-source platform for community discussion, directly into your AI workflow. Manage your forum topics and categories, research community member profiles and trust levels, and track group memberships using natural language.
LangChain's ecosystem of 500+ components combines seamlessly with Discourse through native MCP adapters. Connect 10 tools via the Vinkius and use ReAct agents, Plan-and-Execute strategies, or custom agent architectures — with LangSmith tracing giving full visibility into every tool call, latency, and token cost.
What you can do
- Discussion Oversight — List and retrieve detailed information for the latest topics and trending discussions across your community.
- Category Management — Access the full category tree, resolving structural relationships and visibility settings.
- Member Intelligence — Research user profiles, track trust levels, and list active members in your organization.
