+#
+# MCP-host / Glama image for the Grasp MCP server (stdio transport).
+#
+# This starts the MCP SERVER (dist/index.js — the `grasp-mcp` bin / `npm start`),
+# NOT the `grasp` CLI in docker/Dockerfile (which runs `grasp --help`). MCP hosts
+# and Glama's evaluator need the server to start on stdio and answer the MCP
+# handshake (initialize / tools/list), which the CLI image cannot do.
+#
+# The server runs with no configuration (public repos, 60 GitHub req/hr). Set
+# GITHUB_TOKEN for 5,000 req/hr and private-repo access.
+#
+# Build from the repository root:
+#   docker build -t grasp-mcp .
+#   docker run --rm -i grasp-mcp
+#
+# The build stage mirrors docker/Dockerfile so it stays in lock-step with the
+# published `grasp-mcp-server` package.
