naramarket-pro-MCP

This is an MCP server that integrates 6 types of KONEPS (Korea ON-line E-Procurement System) public procurement APIs. You can connect it to MCP clients like Claude Desktop to perform tasks such as searching for bid notices, analyzing the market, and evaluating bid suitability using natural language.

Key Features

Integration of 6 Public Procurement APIs

We have integrated major KONEPS public APIs to allow for the retrieval of various data.

• Bid Notices: Search for notices by keyword, organization, and period.

• Bid Results: Retrieve information on winning bidders and amounts.

• Contract Information: Verify actual contract execution details.

• Integrated Contract Process Disclosure: Track the entire process from pre-specifications to contracts.

• Procurement Requests: Retrieve data from the pre-ordering stage.

• Comprehensive Shopping Mall Items: Search for items registered under unit price contracts.

The common API client (api/client.py) handles the following functions:

• Normalization of response formats

• Automatic retries on request timeouts (up to 2 times)

• Memory caching (default 5 minutes)

8 MCP Tools

Configured as functional tools for efficient use in LLM environments.

Natural Language Processing

Implemented to automatically convert user input in everyday language into API parameters.

Period Expressions — last 7 days / past 3 months / this year

Amount Expressions — 500 million / 150 million / 30 million won

Work Category Synonyms — service → service / construction → construction work

State Storage

Stores user configuration data based on SQLite. Saved items include Watchlist and company profiles; the default storage location is as follows.

~/.narajangteo-pro/state.db
