+### Tools
 
-### Built-in tools
+GraphChat includes a set of **built-in tools** and supports
+creating **custom Cypher-backed tools**.
+
+{<h4 className="custom-header">Built-in tools</h4>}
+
+Built-in tools cover a variety of tasks such as querying data,
+retrieving database information, running graph algorithms,
+checking indexes, managing triggers, and more:
 
-GraphChat gives models access to built-in tools that allow them to query your
-data, inspect the database, and run algorithms:
 * `run-cypher-query`: Generate and execute a Cypher query.
-* `run-page-rank`: Identify the most connected and impactful node using PageRank.
-* `run-betweenness-centrality`: Determine which nodes serve as critical bridges in the graph.
-* `show-config`: List all Memgraph database configuration parameters.
-* `show-schema-info`: Display the full database schema (requires `--schema-info-enabled` flag on startup).
-* `show-storage-info`: View memory usage, available memory, disk usage, and counts of nodes and relationships.

+
+{<h4 className="custom-header">Cypher-backed tool</h4>}

+tools by providing:
+
+* A tool name
+* A description
+* A parameterized Cypher query to execute on call
+
+![graphchat-toolkit-custom](/pages/data-visualization/features/graphchat/toolkit-custom.png)

+Make sure each custom tool has a unique name and clear description
+so the LLM can accurately select the appropriate tool when responding.
 
-If you want to replicate this behavior, disable all other tools in the configuration.
+### MCP servers
 
-{<h4 className="custom-header">Enhanced tool support from Lab 3.3 onward</h4>}
+Starting with Lab 3.6, you can integrate tools from MCP servers,
+where Lab acts as an MCP client. This greatly expands the
+capabilities of the assistant in GraphChat, allowing it to
+leverage external tools beyond the built-in and custom ones.
 
-Starting with Lab 3.3, GraphChat can use all built-in tools automatically. The
-LLM decides which tool to use based on the context of the question.
+![mcp-servers-settings](/pages/data-visualization/features/graphchat/mcp-servers-settings.png)
 
-You can also define your own **custom tools** by providing:
-* A **tool name**
-* A **description**
-* A **parameterized Cypher query**
+{<h4 className="custom-header">Setting up the connection</h4>}
 
-Ensure each custom tool has a distinct name and description so the LLM can
-choose the right one.
+In Settings/LLM tab, you can create and manage MCP connections.
+Lab currently supports a streamable HTTP transport layer. To
+set up a connection:
+
+* Enter the **URL** where your MCP server is listening.
+* (Optional) Add an **access token** - it will be sent as an
+  Authorization header.
+* (Optional) Add any **custom headers** required by your MCP server.
+
+Upon a successful connection, Lab retrieves a list of tools provided
+by the MCP server. You can then select which of these tools you
+want to enable in GraphChat.
+
+GraphChat automatically resyncs tools and MCP connections each
+time you open a new GraphChat view. If there's an issue with a
+connection, the affected tools will be unavailable, and you'll
+see the error response that explains why the connection
+failed - helping you troubleshoot and resolve the issue.
+
+{<h4 className="custom-header">Managing MCP tools in GraphChat</h4>}
+
+Once an MCP connection is set up in Lab, you can manage its
+tools directly within GraphChat. When you open the tools list
+from the input box in GraphChat, you'll see:
+
+* All your active MCP servers
+* The tools each server provides
+
+![toolkit-mcp](/pages/data-visualization/features/graphchat/toolkit-mcp.png)
+
+You can choose which tools to enable for the current GraphChat
+conversation. Additionally, you can quickly enable or disable
+all tools from a specific MCP server with a single action - making
+it easy to tailor the toolset to your workflow.
