Overview

The edition-api MCP server gives AI agents structured knowledge about operating, traveling, and living in Japan. It connects through a local MCP process to the EDITION production API at api.edition.sh, using configured URL and API key values. Tools cover 20 domains, including regulation, business protocol, language, travel, immigration, tax, healthcare, and disaster safety. Reach for it when an agent needs Japan-specific procedures, cultural context, compliance checks, or cross-domain search rather than generic language-model knowledge.

Use cases

  • Research company incorporation and visa steps in Japan
  • Check Japanese business protocols and honorific language
  • Answer travel, dining, healthcare, and daily-life questions
  • Search regulations across multiple Japanese industries
  • Create compliance audit records after regulatory checks

Key features

  • 20 Japan-focused knowledge domains
  • 43 MCP tools for search and domain checks
  • Cross-domain knowledge search
  • Japanese-aware persistent memory
  • Seven documented Skills Packs
  • Compliance logging and reporting

How Edition API works

What the edition-api MCP server does

The edition-api MCP server exposes Japan-focused operational knowledge to AI agents through the Model Context Protocol. Its material spans business formation, regulatory questions, workplace customs, travel, food, healthcare, education, housing, banking, taxation, immigration, disaster response, and everyday administration.

The repository describes 20 knowledge domains and 43 MCP tools. Each domain generally provides search or check operations plus list operations, while a cross-domain search tool can query all domains in one request. The content is intended to provide structured reference information for situations where Japanese procedures, terminology, cultural expectations, or local rules matter.

Memory tools add a separate capability for storing episodes, recalling information, retrieving facts, building context, and extracting structured knowledge. The documented memory model separates raw conversation episodes, extracted subject-predicate-object facts, and aggregated context. Extraction can include Japanese honorific analysis, social hierarchy detection, confidence scoring, and tense.

How it works

The package runs as an MCP server and forwards agent requests to the EDITION API. The documented production endpoint is https://api.edition.sh, and the API is described as a free beta that does not require registration. The repository also documents direct REST calls for search, regulation checks, and protocol checks, but the MCP package is the route intended for MCP clients.

Tools are grouped by subject. Examples include regulation_check for industry-related rules, protocol_check for practices such as nemawashi and ringi, calendar_check for Japanese business and administrative timing, foreign_entry_check for incorporation and visa-related procedures, and travel_search for transport, etiquette, and tourist questions. Governance tools can record an immutable, timestamped compliance event with compliance_log and produce summary, detailed, or JSON reports with compliance_report.

Seven documented Skills Packs combine domain guidance with procedures and orchestration instructions. They cover market entry, business operations, travel, daily living, cultural context, safety and compliance, and governance compliance.

Setup and configuration

The recommended installation uses the published npm package:

Terminal
npx -y edition-mcp-server

Configure the MCP client to start that command and provide EDITION_API_URL and EDITION_API_KEY. The example configuration uses https://api.edition.sh and the development key edition_dev_key_for_testing. The README specifically shows setup examples for Claude Desktop and Cursor. A Smithery installation command is also documented:

Terminal
npx -y smithery mcp add hiroshi-c9/edition

The repository additionally provides a hosted API path for clients or applications that use HTTP directly instead of MCP.

Tools and capabilities

The edition-api MCP server documents tools for:

  • Searching all domains or querying a specific subject area.
  • Checking Japanese regulations across industries and tourist activities.
  • Explaining business protocols, hierarchy, regional differences, calendars, and language.
  • Supporting company incorporation, management visas, banking, tax, real estate, and hiring research.
  • Answering travel, food, entertainment, healthcare, education, safety, and daily-life questions.
  • Storing and extracting Japanese-aware memory with facts, context, hierarchy, and confidence information.
  • Creating and reporting governance audit trails after regulatory checks.

The listed Skills Packs can help skills-aware agents load a predefined combination of domains for a particular workflow.

Limitations and notes

The repository contains inconsistent counts in its surrounding description: the current README presents 20 domains and 43 tools, while the supplied current description mentions 10 domains and 23 tools. This writeup follows the detailed README tables. The service is described as a free beta, so its availability and behavior may change. Regulatory, immigration, tax, healthcare, and safety information should be checked against the relevant official authority before making a consequential decision.
