What is the 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.
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).
How it works
- Add the Relevance AI extension to your MCP hub.
- Supply your
Project ID,API Key, and your assignedRegion(e.g., "us-east-1" or "v2") from your Relevance AI settings. - Prompt your assistant: "Trigger the 'Lead Research' agent with the company name 'Google' and monitor the run until completion. Then, insert the output directly into our 'competitors' dataset."
Who is this for?
- AI Engineers & Builders — Run end-to-end tests on your chained logic and customized agents directly from your terminal or chat without touching the studio GUI.
- Data Analysts — Move processed insights, raw texts, and structured metadata into Relevance AI datasets using natural language.
- Operations Teams — Combine the output of your everyday AI chat intimately with your specialized Relevance AI autonomous agents for highly productive compounding workflows.

Frequently asked questions
Can the agent monitor a long-running relevance AI agent task?
Yes. You can trigger an agent using trigger_agent, and because it provides a run_id, you can explicitly prompt your local Assistant to periodically "check in on the status using get_agent_run every minute until finished" or ask it to summarize the step-by-step agent logs after completion.
What is the differences between tasks, tools, and agents in Relevance AI?
Agents are autonomous workers capable of making step-by-step reasoning choices based on instructions and tools. Tasks are linear, pre-chained sets of commands and prompts. Tools (list_tools) are the individual capabilities, like a custom API integration or web scraper, that tasks and agents utilize to perform their actions.
How do I find my specific Region and Project ID?
These details are typically nested within the URL string when you are logged into your workspace or found globally in your developer API keys configuration pane inside your Relevance AI team dashboard. The Region is usually something like 'us-east-1' or 'v2'.
How does LangChain connect to MCP servers?
Use langchain-mcp-adapters to create an MCP client. LangChain discovers all tools and wraps them as native LangChain tools compatible with any agent type.
Which LangChain agent types work with MCP?
All agent types including ReAct, OpenAI Functions, and custom agents work with MCP tools. The tools appear as standard LangChain tools after the adapter wraps them.
Can I trace MCP tool calls in LangSmith?
Yes. All MCP tool invocations appear as traced steps in LangSmith, showing input parameters, response payloads, latency, and token usage.
