Zendesk API MCP Server

Implementation Reference

• src/tools/organizations.js:12-27 (handler)

  The MCP tool handler function for 'list_organizations' that prepares parameters, calls the Zendesk client, and returns the result as JSON or an error message.

  handler: async ({ page, per_page }) => {
    try {
      const params = { page, per_page };
      const result = await zendeskClient.listOrganizations(params);
      return {
        content: [{ 
          type: "text", 
          text: JSON.stringify(result, null, 2)
        }]
      };
    } catch (error) {
      return {
        content: [{ type: "text", text: `Error listing organizations: ${error.message}` }],
        isError: true
      };
    }

• src/tools/organizations.js:8-11 (schema)

  Zod schema defining optional input parameters 'page' and 'per_page' for pagination.

  schema: {
    page: z.number().optional().describe("Page number for pagination"),
    per_page: z.number().optional().describe("Number of organizations per page (max 100)")
  },

• src/server.js:47-52 (registration)

  Loop that registers all tools, including 'list_organizations', with the MCP server by calling server.tool() for each.

  // Register each tool with the server
  allTools.forEach((tool) => {
    server.tool(tool.name, tool.schema, tool.handler, {
      description: tool.description,
    });
  });

• src/tools/organizations.js:4-29 (registration)

  Definition and export of the organizationsTools array containing the 'list_organizations' tool specification.

  export const organizationsTools = [
    {
      name: "list_organizations",
      description: "List organizations in Zendesk",
      schema: {
        page: z.number().optional().describe("Page number for pagination"),
        per_page: z.number().optional().describe("Number of organizations per page (max 100)")
      },
      handler: async ({ page, per_page }) => {
        try {
          const params = { page, per_page };
          const result = await zendeskClient.listOrganizations(params);
          return {
            content: [{ 
              type: "text", 
              text: JSON.stringify(result, null, 2)
            }]
          };
        } catch (error) {
          return {
            content: [{ type: "text", text: `Error listing organizations: ${error.message}` }],
            isError: true
          };
