About Relevance AI MCP Server
Connect your conversational AI to your Relevance AI workspace. By wrapping your custom agents, datasets, and API tools into this MCP extension, you transform your chat interface into a command center for orchestrating complex, autonomous AI operations and large-scale data workflows.
LangChain's ecosystem of 500+ components combines seamlessly with Relevance AI through native MCP adapters. Connect 10 tools via 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
- Orchestrate Agents — Command your pre-built autonomous agents to execute tasks (
trigger_agent). Monitor their progress and read their exact reasoning steps dynamically (get_agent_run). Uselist_agentsto discover all available AI worker configurations. - Execute Tasks & Workflows — Trigger predefined chained prompts or specific micro-tasks without leaving your chat (
trigger_task), scaling repetitive workflows reliably. - Manage Knowledge Datasets — Take full control of your vector databases and tables. Insert new rows of knowledge directly from conversational context (
insert_documents), retrieve raw unstructured data entries (get_documents), or surgically delete obsolete knowledge base items (delete_documents).
The Relevance AI MCP Server exposes 10 tools through the Vinkius. Connect it to LangChain in under two minutes — no API keys to rotate, no infrastructure to provision, no vendor lock-in. Your configuration, your data, your control.
