Implementation Reference

• index.ts:776-827 (handler)

  MCP tool handler case for 'get_page_history': extracts title and limit from arguments, calls wikiClient.getPageHistory(), handles missing page, formats revisions list into JSON response.

  case "get_page_history": {
    const { title, limit = 10 } = request.params.arguments as {
      title: string;
      limit?: number;
    };
    const result = await wikiClient.getPageHistory(title, limit);
  
    const pages = result.query.pages;
    const page = pages[0];
  
    if (page.missing) {
      return {
        content: [
          {
            type: "text",
            text: JSON.stringify(
              {
                title: page.title,
                exists: false,
                message: "Page does not exist"
              },
              null,
              2
            )
          }
        ]
      };
    }
  
    const revisions = page.revisions.map((rev: any) => ({
      id: rev.revid,
      timestamp: rev.timestamp,
      user: rev.user,
      comment: rev.comment
    }));
  
    return {
      content: [
        {
          type: "text",
          text: JSON.stringify(
            {
              title: page.title,
              revisions
            },
            null,
            2
          )
        }
      ]
    };
  }

• index.ts:441-449 (helper)

  MediaWikiClient.getPageHistory(): core implementation that makes the MediaWiki API query for page revisions with specified props and limit.

  async getPageHistory(title: string, limit: number = 10): Promise<any> {
    return this.makeApiCall({
      action: "query",
      prop: "revisions",
      titles: title,
      rvprop: "timestamp|user|comment|ids",
      rvlimit: limit
    });
  }

• index.ts:549-567 (schema)

  Tool schema definition: specifies inputSchema with title (required string) and optional limit (number, default 10).

  const GET_PAGE_HISTORY_TOOL: Tool = {
    name: "get_page_history",
    description: "Get revision history of a page",
    inputSchema: {
      type: "object",
      properties: {
        title: {
          type: "string",
          description: "Title of the page"
        },
        limit: {
          type: "number",
          description: "Maximum number of revisions to return (default: 10)",
          default: 10
        }
      },
      required: ["title"]
    }
  };

• index.ts:598-607 (registration)

  Tool registration: GET_PAGE_HISTORY_TOOL is included in the tools list returned by ListToolsRequestSchema handler.

  server.setRequestHandler(ListToolsRequestSchema, async () => ({
    tools: [
      SEARCH_PAGES_TOOL,
      READ_PAGE_TOOL,
      CREATE_PAGE_TOOL,
      UPDATE_PAGE_TOOL,
      GET_PAGE_HISTORY_TOOL,
      GET_CATEGORIES_TOOL
    ]
  }));
