# syntax=docker/dockerfile:1

# `xerj mcp` as a stdio MCP server in a container, for the Docker MCP

# Catalog (github.com/docker/mcp-registry) and any client that launches

# MCP servers with `docker run -i`.

# This image does not build from source; it fetches the published musl

# release binary and checks it against the release's .sha256 asset. The

# MCP server proxies to a XERJ node, so point XERJ_URL at one you run on

# the host (default below) or elsewhere. The Corpus Hub tools work with

# no node at all.

# docker build -f packaging/docker-mcp/Dockerfile -t xerj-mcp .

# docker run -i --rm -e XERJ_URL=http://host.docker.internal:9200 xerj-mcp

# The server image for the engine itself is engine/Dockerfile.
