+### mcp
+
+Runs the ABP [MCP (Model Context Protocol)](https://modelcontextprotocol.io/) server on your computer, so MCP clients such as Claude Code, Codex, Cursor and Visual Studio Code can search the ABP documentation, community articles, answered support questions and the framework source code.
+
+The command communicates with the MCP client over `stdio` and forwards the tool calls to `https://mcp.abp.io` by default. It uses the credentials of the [logged in](../cli#login) user, so you should run `abp login` before using it and your organization must have an active license. An internet connection is also required: the command checks the server before starting and fails when it can not be reached.
+
+Usage:
+
+```bash
+abp mcp [get-config]
+```
+
+Examples:
+
+```bash
+abp mcp               # Starts the MCP server. MCP clients run this command themselves.
+abp mcp get-config    # Prints the configuration to be added to your MCP client.
+```
+
+#### Configuring your MCP client
+
+`abp mcp get-config` prints the following configuration:
+
+```json
+{
+  "mcpServers": {
+    "abp": {
+      "command": "abp",
+      "args": [
+        "mcp"
+      ],
+      "env": {}
+    }
+  }
+}
+```
+
+Claude Code uses that JSON directly. Add it to the `.mcp.json` file in your solution folder to enable the server for a single solution, or to `~/.claude.json` (`%USERPROFILE%\.claude.json` on Windows) to enable it for all of them. Cursor uses the same format in its own `mcp.json` file. For the other clients, check their documentation for the configuration file and the format they expect; the command and the arguments are always the same.
+
+Codex uses the TOML format, so add the following section to `~/.codex/config.toml` (`%USERPROFILE%\.codex\config.toml` on Windows):
+
+```toml
+[mcp_servers.abp]
+command = "abp"
+args = ["mcp"]
+```
