Overview

AI-generated overview

A hosted MCP server that lets an assistant full-text search Japan's National Diet records from 1947 onward, with speaker, party, date and citation details.

What you can do
Search speeches across Diet records from 1947 to the present, filtering by speaker, house, meeting name and date range, with excerpts or full text and an official citation link per result. Find which plenary sessions and committees discussed a topic and when, to get an overview before reading individual speeches. Results come live from the National Diet Library's official record API on each call.
When to use it
Useful for policy research, journalism, government-affairs and compliance work that needs primary-source Japanese Diet statements, committee Q&A or debate history, including questions about when a topic was last debated and in which committee.
Requirements
A remote hosted endpoint reached over streamable HTTP; no local runtime, package, account, API key or environment variable is declared. The README says it is offered through a third-party store page, and network access is needed for live queries.
Before you install
The README states pay-per-tool-call pricing (one speech or meeting search counts as one event, with a stated per-call price), so usage costs money and should be budgeted. Queries and results pass through the hosted provider and the upstream public record API; verify citations against the official source before relying on them.

Installation

In SourceWeft

  1. Open Japan Parliament Search in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/io.github.fujimura-ui%2Fjapan-parliament-search-mcp/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

README

Japan Parliament Search MCP — 国会会議録検索

Give your AI agent access to every word spoken in Japan's National Diet since 1947.

This MCP server searches the official National Diet Library record system — ministerial statements, committee Q&A, and policy debates — the primary source for understanding Japanese government policy. Built for policy research, journalism, government-affairs, and compliance AI agents.

Why this server?

Japanese policy signals appear in Diet debates months before they become law or regulation. This data is public but effectively invisible to AI agents: Japanese-only, verbose, and buried in a legacy search interface. This server makes it queryable in one tool call.

Tools

search_speeches

Full-text search across all Diet speeches (1947–present). Filter by speaker, house (衆議院/参議院), meeting name, and date range. Returns speaker, position, party, date, an excerpt (or full text with full_text=true), and an official citation URL.

search_meetings

Find which plenary sessions and committees discussed a topic, and when — the bird's-eye view before drilling into individual speeches.

Example queries your agent can now answer

  • 「生成AIについて文部科学大臣は国会でどう答弁している？直近のものを引用して」
  • "When did the Diet last debate semiconductor subsidies, and in which committee?"
  • 「インボイス制度に関する財務省side答弁を2026年に絞って要約して」

Data source & freshness

Official National Diet Library (国立国会図書館) Kokkai Kaigiroku API, fetched live on every call. Records go back to 1947 and include the most recent published sessions.

Pricing
