Hangulport

hangulport

hangulport is a client for the hosted Bareun Korean NLP service. It exposes morphological analysis with part-of-speech tagging, the raw morphological model output, Urimalsaem dictionary search by jamo slot pattern, sentence tokenization, spelling and spacing correction, and the service's part-of-speech tag list. One binary serves a command-line interface and a stdio MCP server; both forward every call to the hosted endpoint.

An API key is required. Set BAREUN_API_KEY to your Bareun key; it is sent to the endpoint as the api-key header and nowhere else. Calls go to https://api.bareun.ai/mcp unless BAREUN_MCP_URL overrides the endpoint. When the key is missing, calls fail with an error naming BAREUN_API_KEY — no result is invented locally. The 47 POS tags behind list_pos_tags are served by the upstream; they are not hardcoded here.

Install

npx @reneturcios/hangulport tokenize "안녕하세요"

Or run the container image:

docker run -i ghcr.io/cloudcorprecords/hangulport

The container defaults to the MCP server (see below). Pass CLI arguments to use it as a CLI instead. Both forms need BAREUN_API_KEY in the environment (for Docker, add -e BAREUN_API_KEY=...).

CLI

hangulport analyze_syntax "안녕하세요" --auto-spacing --encoding utf8 --format compact

hangulport analyze_syntax_raw "안녕하세요" --with-sense hangulport search_dict "ㄱㅏ*" --anchor prefix --limit 5 --with-definition hangulport tokenize "문장을 나눕니다" --auto-spacing hangulport correct_grammar "띄어쓰기연습" --enable-sentence-check hangulport list_pos_tags

hangulport --version

Each subcommand is named after the MCP tool it calls. The first argument is the required text (or dictionary pattern); the remaining flags map one-to-one onto the tool's optional inputs. Boolean flags take no value: passing the flag sets it true, and omitting it forwards nothing — this client injects no defaults of its own. --custom-dict-names takes a comma-separated list. Commands print the upstream result text. Exit codes: 0 on success, 1 when a call fails (including a missing key or an upstream error), 2 for usage errors.

MCP server

One bin serves both faces. The mcp subcommand starts a stdio MCP server:

npx -y @reneturcios/hangulport mcp

MCP client configuration:

{

"mcpServers": { "hangulport": { "command": "npx", "args": ["-y", "@reneturcios/hangulport", "mcp"], "env": { "BAREUN_API_KEY": "your-key" } } } }

To point the server at a different Bareun-compatible host, add BAREUN_MCP_URL to the client's env for this server.
