Implementation Reference

• src/tools/wiki/update.ts:12-61 (handler)

  Core handler function that implements the logic for updating a wiki page, including validation, wiki retrieval, and response formatting (noting current API limitations).

  export async function updateWikiPage(args: UpdateWikiPageArgs, config: AzureDevOpsConfig) {
    if (!args.wikiIdentifier || !args.path || !args.content) {
      throw new McpError(
        ErrorCode.InvalidParams,
        'Wiki identifier, page path, and content are required'
      );
    }
  
    AzureDevOpsConnection.initialize(config);
    const connection = AzureDevOpsConnection.getInstance();
    const wikiApi = await connection.getWikiApi();
  
    try {
      const wiki = await wikiApi.getWiki(config.project, args.wikiIdentifier);
      if (!wiki || !wiki.id) {
        throw new McpError(
          ErrorCode.InvalidParams,
          `Wiki ${args.wikiIdentifier} not found`
        );
      }
  
      const updateParams = {
        content: args.content,
        comment: args.comment || `Updated page ${args.path}`,
      };
  
      // Da die Wiki-API keine direkte Methode zum Aktualisieren von Seiten bietet,
      // geben wir vorerst nur die Wiki-Informationen zurück
      return {
        content: [
          {
            type: 'text',
            text: JSON.stringify({
              wiki,
              path: args.path,
              message: 'Wiki page update is not supported in the current API version',
              requestedUpdate: updateParams
            }, null, 2),
          },
        ],
      };
    } catch (error: unknown) {
      if (error instanceof McpError) throw error;
      const errorMessage = error instanceof Error ? error.message : 'Unknown error';
      throw new McpError(
        ErrorCode.InternalError,
        `Failed to update wiki page: ${errorMessage}`
      );
    }
